很简单，如下：

父页面:（弹出提示框）

function newwindow(obj)

{

var rtn = window.showModalDialog('NewPage.htm','','status=no,scrollbars=no,top=20,left=110,width=420,height=165');

var div = document.getElementById("div1");

div.innerHTML=rtn;

}

子页面：

function pageinit()

{

var lab = document.getElementById("infoimage");

window.returnValue=lab.value;

window.close();

}

---------------------------父窗体

function Show()

{

var bb=2;

var a=window.showModalDialog("弹出2.aspx","","dialogwidth=500px;dialogheight=500px;");

document.getElementById("Text1").value=a;

}

-----------------------------子窗体

function Button1_onclick() {

var a=document.getElementById("TextBox1");

window.returnValue=a.value;

window.close();

------------------window.dialogArguments

}

-------------------------------------------------后台调用前台js函数；

ClientScript.RegisterStartupScript(ClientScript.GetType(), null, "<script>guo('fffff');</script>");

--------------------------sd可以使name,或者是Id；

document.all("sd").style["height"]=h;//设置样式,js控制样式

-------------------------调节透明度

#guo {

filter:alpha(opacity=50);

}

</style>

--------------------------------调用客户端事件：

ScriptManager.RegisterStartupScript(UltraWebGrid1, typeof(UltraWebGrid), "null", "<script>window.parent.gb('T');</script>", false);

---------------调用frame框架外的函数：

------------------iframe获取父页面的元素

window.parent.document.getElementById("Text1").value="hahhahhaha";

父亲获取儿子

JS版：document.getElementById("IframeID").contentWindow.document.getElementById("divID")

--------------------------------js星期：

var day=["日","一","二","三","四","五","六",];

document.write("星期"+day[new Date().getDay()]);

-----------------------------------

Infragistics.WebUI.UltraWebListbar.UltraWebListbar bar = new Infragistics.WebUI.UltraWebListbar.UltraWebListbar();

bar.ID = "menu";

bar.SkinID = "MenuBar";

bar.ApplyStyleSheetSkin(Page);

//bar.Width=

//bar.Height = "100%";

bar.Groups.Clear();

YongHuModel userModel= Session["LoginUser"] as YongHuModel;

int roleId = userModel.RoleId.Id;

IList<RoleLines> roleLines = RoleLinesManager.GetSYSMenu(roleId);

foreach (RoleLines roleItem in roleLines)

{

if (roleItem.LinkId.ParentId == 0)

{

//Infragistics.WebUI.UltraWebNavigator.Node root = new Node();

//root.Text = roleItem.LinkId.Name;

//root.DataKey = roleItem.LinkId.Id;

//root.Expanded = true;

//root.ImageUrl = "~/XtGlMk/images/base.gif";

TreeNode root = new TreeNode();

root.Text = roleItem.LinkId.Name;

root.Value = roleItem.LinkId.Id.ToString();

root.Expanded = true;

root.NavigateUrl = "";

Infragistics.WebUI.UltraWebListbar.Group group = new Infragistics.WebUI.UltraWebListbar.Group(root.Text);

MyTemplate tem = new MyTemplate();

tem.Lines = roleLines;

tem.Root = root;

group.Template = tem;

bar.Groups.Add(group);

}

bar.DataBind();

Panel1.Controls.Add(bar);

----------------------------------------------------treeNode节点添加：

continue;

}

FillTemp(node, entity.LinkId.Id);

}

---------------------------------------listbar:

Infragistics.WebUI.UltraWebListbar.Group group = new Infragistics.WebUI.UltraWebListbar.Group("aa");

Infragistics.WebUI.UltraWebListbar.Item ite1 = new Infragistics.WebUI.UltraWebListbar.Item();

ite1.Text = "aaaa";

group.Items.Add(ite1);

this.UltraWebListbar1.Groups.Add(group);

----------------------------------------

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('请选择要删除的行！');</script>", false);

------------------------------------------scriptmanage中使用控件netadvantage能够使用；webconfig文件

</httpHandlers>

---------------------------

<p style="padding-top:5px;">欢迎您</p> 若换成<span>就不好用了；

------------------------viewstate类似于static

-------------------------分页：

string sql2 = "select top " + page.PageSize + " * from GongSi where BH not in(select top " + page.Start + " BH from GongSi)";

---------------------------gridview中添加控件

<igtbl:TemplatedColumn Width="200px">

操作

</HeaderTemplate>

<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" Width="80px">下属用户</asp:LinkButton>

</CellTemplate>

</Header>

</Footer>

</igtbl:TemplatedColumn>

---------------------------------------------------------------------------------获取gridview的表格值，cell值：

Session["Id"] = UltraWebGrid1.DisplayLayout.SelectedCells[0].Row.Cells[0];

Session["Id"] = UltraWebGrid1.DisplayLayout.SelectedRows[0].Cells[0].ToString();

案例：

if (UltraWebGrid2.DisplayLayout.SelectedCells[0] != null)

{

if (UltraWebGrid2.DisplayLayout.SelectedCells[0].Row != null)

{

int id = Convert.ToInt32(UltraWebGrid2.DisplayLayout.SelectedCells[0].Row.Cells[0].Text);

Session["XgGsID"] = id;

Response.Redirect("XgGongSi.aspx");

}

else

{

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('请选择要修改的行！');</script>", false);

}

else

{

if (UltraWebGrid2.DisplayLayout.SelectedRows[0] != null)

{

int id = Convert.ToInt32(UltraWebGrid2.DisplayLayout.SelectedRows[0].Cells[0].Text);

Session["XgGsID"] = id;

Response.Redirect("XgGongSi.aspx");

}

else

{

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('请选择要修改的行！');</script>", false);

}

-------------------------------------------------------------------------------------------

----------------listbox添加项：

foreach (YongHuModel model in yhgl_models)

{

ListItem li = new ListItem();

li.Text = model.MC.ToString();

li.Value = model.BH.ToString();

cblJZXM.Items.Add(li);

}

------------------------------------------------listbox:添加移除列；

cblJZXM.Items.Add(li);

//移除

cblXM.Items.RemoveAt(i);

------------------------------------------------弹出框案例：

父页面案例：弹出提示框

function Button1_onclick() {

window.showModalDialog("子.aspx",this,"dialogHeight:450px;dialogWidth:800px;status=no");

}

function show(str)

{

document.getElementById("Text1").value=str;

}

</script>

//子页面案例：后台---

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "null",

"<script>window.dialogArguments.addgs('" + GYSBH + "','" + MC + "');window.close();</script>", false);

必须在head内添加：

-----------------------------------后台获取前台session值：

string dataBaseName=System.Web.HttpContext.Current.Session["XmName"].ToString();

//--------------------------------------查询某数据库某个表：

SELECT * FROM CC ..AA

------------------------------------------

cmd.Parameters.AddRange(values);//循环添加sqlparameters

-----------------------------------------------------------------

using(SqlDataReader sdr=DBHelper.GetReader(sql1))，使用using的前提是对象类必须是实现：Idispose接口；

{

if (sdr.Read())

{

return 0;

}

--------------------------------------------------------------------------------------------------前台：

function IfGoDel(bh)

{

if(confirm("是否同时删除合格供应商名册与供应商复核里的数据？"))

{

document.getElementById("hidCommond").value="allDel";

document.getElementById("hidXtBH").value=bh;

}else

{

document.getElementById("hidCommond").value="Only";

document.getElementById("hidXtBH").value=bh;

}

// __doPostBack("UpdatePanel1","");

document.form1.submit();

}

--------后台:

string commond = Request.Form["hidCommon"];

if (commond == "Search")

{

Bind(1);

}

string commd = Request.Form["hidCommond"];

string xtbh = Request.Form["hidXtBH"];

if (commd == "allDel")

{

int key = Convert.ToInt32(xtbh);

bool bb = GysFpManager.dropGysFPByBH(key);

if (bb)

{

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('删除成功！');</script>", false);

Bind(1);

}

else

{

ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "Button2",

"<script>alert('删除失败！');</script>", false);

}

if (commd == "Only")

{

return;

}

-----------------------------------数据库分页；

List<GysModel> GysS = new List<GysModel>();

List<SqlParameter> pars = new List<SqlParameter>();

string searchSql = CreatSql(searchModel, pars);

string selectCount = "select count(*) from Gys where (FHJG=1 or FHJG is null ) " + searchSql;

page.TotalRow = Convert.ToInt32(DBHelper.GetScalar(selectCount, pars.ToArray()));

StringBuilder sql = new StringBuilder("select * from (select row_number() OVER (ORDER BY BH desc) AS rowId,* from Gys where (FHJG=1 or FHJG is null )");

sql.Append(searchSql).Append(")as Temp where rowId between ").Append(page.Begin).Append(" and ").Append(page.End);

using (SqlDataReader dr = DBHelper.GetReader(sql.ToString(), pars.ToArray()))

{

while (dr.Read())

----------------------------------------添加事务：

begin transaction

insert into A(c1,c2) values(v1,v2);

insert into B(c3,c4) values(v3,v4);

insert into C(c5,c6) values(v5,v6);

if @@ERROR = 0

begin

commit transaction;

end

else

begin

rollback transaction;

end

---------------------------这条语句是正确的

cn = new SqlConnection("data source=DELL-PC\\AA;uid=sa;pwd=sa");

cn.Open();

StringBuilder sb = new StringBuilder(" use CC update [User] set UName='666' where UId="+i+"");

-----------------------------这条语句也是正确的；

cn = new SqlConnection("data source=DELL-PC\\AA;initial catalog=CC; uid=sa;pwd=sa");

cn.Open();

StringBuilder sb = new StringBuilder(" use CD update [User] set UName='666' where UId="+i+"");

---------------------------------同时对两个数据库进行操作

try

{

int i = 1;

cn = new SqlConnection("data source=DELL-PC\\AA;initial catalog=CC; uid=sa;pwd=sa");

cn.Open();

StringBuilder sb = new StringBuilder("begin transaction ");

sb.Append("use CC update [User] set UName='xiao' where UId=1");

sb.Append("use CD update [User] set UName='xiao' where UId=1");

sb.Append("if @@ERROR = 0 begin commit transaction end else begin rollback transaction end");

SqlCommand cmd = new SqlCommand(sb.ToString(), cn);

cmd.ExecuteNonQuery();

}

------------------------------

cmd.Parameters.AddRange(values);

--------------------------------------

List<GysFhModel> GysFhS = new List<GysFhModel>();

List<SqlParameter> pars = new List<SqlParameter>();

string searchSql = CreatSql(searchModel, pars);

string selectCount = "select count(*) from GYSFH left join GYS on GYSFH.GYSBH=GYS.BH where 1=1 " + searchSql;

page.TotalRow = Convert.ToInt32(DBHelper.GetScalar(selectCount, pars.ToArray()));

StringBuilder sql = new StringBuilder("select * from (select row_number() OVER (ORDER BY GYSFH.BH desc) AS rowId,GYSFH.* ,GYS.MC from GYSFH left join GYS on GYSFH.GYSBH=GYS.BH where 1=1 ");

sql.Append(searchSql).Append(")as Temp where rowId between ").Append(page.Begin).Append(" and ").Append(page.End);

------------------------javascript:后台提交

document.getElementById("HiddenField1").value="1233434";

var b=document.getElementById("HiddenField2");

window.form1.submit();

接收 if (IsPostBack)

{

TextBox1.Text = HiddenField1.Value.ToString();

}

------------------------将数据库备份到指定位置；

backup database cc to disk='D:\d3.bak'

-----------------------将备份还原到某个位置并附加数据库：格式不能变化；

restore database SJCL33 from disk='D:\Company\通用版\JC.Web\File\BakSource\TSSJCL.bak' with FILE = 1, move 'SJCL' to 'C:\Users\dell\Desktop\s\SJCL33.mdf',move 'SJCL_Log' to 'C:\Users\dell\Desktop\s\SJCL33.LDF',NOUNLOAD, REPLACE, STATS = 10

---------------------------

document.write("浏览器名称: " + navigator.appName + "<br>");

document.write("版本号: " + navigator.appVersion + "<br>");

document.write("代码名字: " + navigator.appCodeName + "<br>");

document.write("用户代理标识: " + navigator.userAgent);

---------------------------bit类型数据存储

插入时可以存：

INSERT INTO Users(Sex) VALUES('TRUE');

0为false,1为true;

或者直接插入0或1；插入时除了整形不带单引号其余都带；

显示时也为True或false;

-----------------------------存储过程整形作为条件

ALTER PROCEDURE dbo.selectuser

(

@UId int,

@result nvarchar(20) output

)

declare @s nvarchar(100)

set @s=@UId

declare @str nvarchar(1000)

set @str='select @result=UName from [User] where UId='''+@s+''''//一个或是三个单引号都行；若是整形，先赋值给字符型就行了

EXEC sp_executesql @str, N'@result nvarchar(20) OUTPUT', @result OUTPUT

--------------------------------数据库分页存储过程

"select UName from [User] where UName like '%"+ss+"%'"

ALTER PROCEDURE dbo.SelectPages

(

@name int,

@pageSize INT, --每页显示的索引号

@pageIndex INT, --每页显示的记录数

@count INT OUTPUT --总记录数

)

begin

declare @na nvarchar(20)

set @na=@name

declare @sqlstrc nvarchar(2000)

declare @sqlstrd nvarchar(2000)

set @sqlstrc='select @count=count(*) from Fen where Name>'''+@na+''''

exec sp_executesql @sqlstrc, N'@count int output',@count output

set @sqlstrd='select Name from (select Name,ROW_NUMBER() OVER (ORDER BY Id) AS SerialNumber from Fen where Name>'''+@na+''') as t'

set @sqlstrd=@sqlstrd+' WHERE t.SerialNumber > ' + CONVERT(NVARCHAR(100), (@pageIndex - 1) * @pageSize) +

' AND t.SerialNumber <= ' + CONVERT(NVARCHAR(100), @pageIndex * @PageSize)

exec (@sqlstrd)

end

-----------------------------------------------------------------------cube grouping rollup的使用；

SELECT CASE WHEN grouping(Name)=1 THEN '合计' ELSE Name END as 姓名,

CASE WHEN grouping(Sex)=1 THEN '合计' ELSE sex END as 性别

,sum(Score) as 总成绩

from Score

GROUP BY name,Sex WITH CUBE

--当出现with rollup 根据by后面第一个字段分组进行汇总，聚合性别；

--若group by sex,Name WITH rollup则根据性别分组，聚合姓名；(男的有多少，女的有多少)

---若with cube,则以group by 后面的多列进行分组，多个维度分组；by后的第一个字段；(顺序为:根据性别聚合,总聚合,根据名称聚合)

------------count(1)和count（*）是等效的，都会返回本列的行数；

-------------------------------------------------------------------统计报表（合计、小计：cube rollup grouping的用法）

create table #t(a int,b int,c int,d int,e int)

insert into #t values(1,2,3,4,5)

insert into #t values(1,2,3,4,6)

insert into #t values(1,2,3,4,7)

insert into #t values(1,2,3,4,8)

insert into #t values(1,3,3,4,5)

insert into #t values(1,3,3,4,6)

insert into #t values(1,3,3,4,8)

insert into #t values(1,3,3,4,7)

insert into #t values(2,2,2,4,5)

insert into #t values(2,2,3,4,6)

insert into #t values(2,2,4,4,7)

insert into #t values(2,2,5,4,8)

insert into #t values(2,3,6,4,5)

insert into #t values(2,3,3,4,6)

insert into #t values(2,3,3,4,8)

insert into #t values(2,3,3,4,7)

情况一：只有一个分类汇总列时，只需要一个合计。只需要增加with rollup即可。（一个维度的）

select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,

sum(b),sum(c),sum(d),sum(e) from #t group by a with rollup

情况二:有多个分类汇总列，只需要一个合计.增加rollup之后，需要增加判断。

select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,

sum(c),sum(d),sum(e) from #t

group by a,b with rollup

having grouping(b)=0 or grouping(a)=1

select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,

sum(d),sum(e) from #t

group by a,b,c with rollup

having grouping(c)=0 or grouping(a)=1

情况三：有多个分类汇总列，需要全部的小计和合计

select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,

case when grouping(b)=1 and grouping(a)=0 then '小计' else cast(b as varchar) end b,

case when grouping(c)=1 and grouping(b)=0 then '小计' else cast(c as varchar) end c,

sum(d),sum(e) from #t

group by a,b,c with rollup

另外一种显示小计的方式

select case when grouping(a)=1 then '合计'

when grouping(b)=1 then cast(a as varchar)+'小计'

else cast(a as varchar) end a,

case when grouping(b)=0 and grouping(c)=1

then cast(b as varchar)+'小计' else cast(b as varchar) end b,

case when grouping(c)=1 and grouping(b)=0

then '' else cast(c as varchar) end c,

sum(d),sum(e) from #t

group by a,b,c with rollup

情况四：有多个分类汇总列，需要部分的小计和合计

select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,

case when grouping(c)=1 and grouping(b)=0 then '小计' else cast(c as varchar) end c,

sum(d),sum(e) from #t

group by a,b,c with rollup

having grouping(a)=1 or grouping(b)=0

---

select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,

case when grouping(b)=1 and grouping(a)=0 then '小计' else cast(b as varchar) end b,

sum(d),sum(e) from #t

group by a,b,c with rollup

having grouping(a)=1 or grouping(b)=1 or grouping(c)=0

select case when grouping(a)=1 then '合计' else cast(a as varchar) end a,

case when grouping(c)=1 and grouping(b)=0 then '小计' else cast(c as varchar) end c,

sum(d),sum(e) from #t

group by a,b,c with rollup

having grouping(a)=1 or grouping(b)=0

{

foreach (DataRow row in ta.Rows)

{

strB.Append(GetSgbIds(row["BH"].ToString()));

}

return strB.ToString();

}

---------------------------------------------对于存储过程中in(@str),这样是不好用的解决方案有两个

1.经语句赋值个字符串，再exec();:::in ('+@sgbids+')

2.利用逗号分割函数进行

--------------------------padding可以扩展元素的空间，比如《a> href>背景范围比较小，所以需要扩展一下；这样背景就变大了；

----------------页面布局时候：

行级元素通过padding来扩展空间：

块级元素通过 line-height:100px; padding:8px 12px;两者来扩充空间，因为块状不能自动调节行高，二行级可以。

---------------------------搜索引擎设置(至于title下面)

为搜索引擎准备的内容

代码如下，替换成你自己站点的内容就可以：

? 允许搜索机器人搜索站内所有链接。如果你想某些页面不被搜索，推荐采用robots.txt方法

? 设置站点作者信息

? 设置站点版权信息

? 站点的简要介绍(推荐)

? 站点的关键词(推荐)

, xhtml, css, graphic, design, layout, usability, cces

sibility, w3c, w3, w3cn, ajie" name="keywords" /> 先介

绍这么多。补充说明，前面花了5节都是讲head区的代码，实际页面

内容还一字未提，呵呵，不要急，其实head区是非常重要的，看一个页面

的head的代码就可以知道设计师是否够专业。

select len('123')返回3；

select ltrim(' 123')//消除左侧空格。rtrim消除右侧空格

select left('1234',2)//取左侧两位

select right('1234',2)

select replace('abcdef','ab','00')

------------结果是00cdef

--------------------

select stuff('abcde',2,3,'11111'):从第2个字符截取3个再塞入最后的字符：a1111e

------------

select dateadd(yy,4,getdate())//加年限yy,改为mm,改为dd获取天数

SELECT datediff(mm,getdate(),'2012-9-2')

select datename(dw,getdate())//返回日期的周几切记返回的是字符串

sign(@A)若符号是-，返回-1，+返回1,0返回0

sqrt(16),平方根4；

round();近似值

power(2,4);2sup4;

floor(a):小于等于a的最小整数；

ceiling:大于或等与最大整数值；

60-100的随机数：rand()*40+60即可；

select convert(INT,'123') 或 select cast('123' as int)

select 1+'2'//返回3；

datalength();返回字节数，一个汉字两个字节，但是len()返回个数

system_user登陆名；

select isnull(mess,'哈哈') from xin：如果为空的话改为哈哈输出

set @str2=substring(@str1,0,@num)、

min,max,avg,count,;

----------分组查询：多列分组；

group by id,iid,但二二对应，顺序不变

select distinct GTime from Grade

param[4].Value!=DBNull.Value

if exists (select * from sysobjects where id = object_id(N’[存储过程名]’) and OBJECTPROPERTY(id, N’IsProcedure’) = 1)

drop procedure [存储过程名] if exists (select * from sysobjects where id = object_id(N’[存储过程名]’) and OBJECTPROPERTY(id, N’IsProcedure’) = 1)

drop procedure [存储过程名]

4 判断临时表是否存在

Sql代码

if object_id(’tempdb..#临时表名’) is not null

drop table #临时表名 if object_id(’tempdb..#临时表名’) is not null

drop table #临时表名

5 判断视图是否存在

Sql代码

--SQL Server 2000

IF EXISTS (SELECT * FROM sysviews WHERE object_id = ’[dbo].[视图名]’

--SQL Server 2005

IF EXISTS (SELECT * FROM sys.views WHERE object_id = ’[dbo].[视图名]’ --SQL Server 2000

IF EXISTS (SELECT * FROM sysviews WHERE object_id = ’[dbo].[视图名]’

--SQL Server 2005

IF EXISTS (SELECT * FROM sys.views WHERE object_id = ’[dbo].[视图名]’

6 判断函数是否存在

Sql代码

-- 判断要创建的函数名是否存在

if exists (select * from dbo.sysobjects where id = object_id(N’[dbo].[函数名]’) and xtype in (N’FN’, N’IF’, N’TF’))

drop function [dbo].[函数名] -- 判断要创建的函数名是否存在

if exists (select * from dbo.sysobjects where id = object_id(N’[dbo].[函数名]’) and xtype in (N’FN’, N’IF’, N’TF’))

drop function [dbo].[函数名]

print ’自增列’

else

print ’不是自增列’

SELECT * FROM sys.columns WHERE object_id=OBJECT_ID(’表名’)

AND is_identity=1 if columnproperty(object_id(’table’),’col’,’IsIdentity’)=1

print ’自增列’

else

print ’存在’

else

print ’不存在 if exists(select * from sysindexes where id=object_id(’表名’) and name=’索引名’)

print ’存在’

else

print ’不存在

11 查看数据库中对象

Sql代码

SELECT * FROM sys.sysobjects WHERE name=’对象名’ SELECT * FROM sys.sysobjects WHERE name=’对象名’

//sql语句优化：

1.尽量使用存储过程

2.使用存储过程建立表外链是最好所有的存储过程锁定表的顺序最好一样，否则会出现死锁现象；

3.避免类型转换；

4.在一个存储过程中使用的结果尽量保存到一个变量中去，这样减少运算；

5.尽量少使用count的函数，消耗内存；

6.存储过程可进行复杂运算减少网络传输；

--------------------------------------------like里面放入变量

SELECT * FROM Info

WHERE

Name

LIKE '%'+@a+'%'

---------------------------------------------多重选择！判断

！第一种用法;select CASE WHEN id=1 THEN 'sdfsdf' WHEN id=2 THEN 'rrsdfs' END as 'asdad'

FROM Info

!第二种用法：

------------------------------------------------------

三范式是一个人根据数学函数提出的：是一种具有最小冗余的表结构

1.第一范式：确保每列的原子行；每个列不可再分割，当然也不要分割的太死；

2.凡是多对多关系，都转为两个一对多关系，从而增添一个关联表；

3.第二范式要求每一个表只做一件事情；重要：表中除了主键列以外的其他列

都要依赖于主键列；（强调依赖关系）

4第三范式：在一个表中消除间接依赖；比如有用户ID就不需要有用用用户姓名了；我勒个去

如何保证表中不能插入相同数据行；（强调直接依赖关系；）

a 1 2 3

a 1 2 4

不能有a 1 2 3,a 1 3 不能再出现；

-----------------------------------------子查询时，当在多个结果中划等号可以用in

select ----where id in (select id from ----)

----------------

if(select Id from b where id>80)//是错误的，if只识别一个返回值，所以改为

if(select Max(id) from b where id>80)即可；

if exists()//可以判断返回多个返回值；

----------------事务

begin transaction

如果没问题的话提交事务；

commit transaction

回滚事务

rollback transaction;

1. 当前系统日期、时间

select getdate()

2. dateadd 在向指定日期加上一段时间的基础上，返回新的 datetime 值

例如：向日期加上2天

select dateadd(day,2,'2004-10-15') --返回：2004-10-17 00:00:00.000

3. datediff 返回跨两个指定日期的日期和时间边界数。

select datediff(day,'2004-09-01','2004-09-18') --返回：17

4. datepart 返回代表指定日期的指定日期部分的整数。

SELECT DATEPART(month, '2004-10-15') --返回 10

5. datename 返回代表指定日期的指定日期部分的字符串

SELECT datename(weekday, '2004-10-15') --返回：星期五

6. day(), month(),year() --可以与datepart对照一下

select 当前日期=convert(varchar(10),getdate(),120)

,当前时间=convert(varchar(8),getdate(),114)

select datename(dw,'2004-10-15')

select 本年第多少周=datename(week,'2004-10-15')

,今天是周几=datename(weekday,'2004-10-15')

函数参数/功能

GetDate( ) 返回系统目前的日期与时间

DatePart('y','2005-7-25 22:56:32')返回值为 206即这一年中第206天

DatePart('yyyy','2005-7-25 22:56:32')返回值为 2005即2005年

SQL Server DATEPART() 函数返回 SQLServer datetime 字段的一部分。

SQL Server DATEPART() 函数的语法是：

DATEPART(portion, datetime)

其中 datetime 是 SQLServer datetime 字段和部分的名称是下列之一： Ms for Milliseconds

Yy for Year

Qq for Quarter of the Year

Mm for Month

Dy for the Day of the Year

Dd for Day of the Month

Wk for Week

Dw for the Day of the Week

Hh for Hour

Mi for Minute

Ss for Second

详细的说明:

通常，你需要获得当前日期和计算一些其他的日期，例如，你的程序可能需要判断一个月的第一天或者最后一天。你们大部分人大概都知道怎样把日期进行分割（年、月、日等），然后仅仅用分割出来的年、月、日等放在几个函数中计算出自己所需要的日期！在这篇文章里，我将告诉你如何使用DATEADD和DATEDIFF函数来计算出在你的程序中可能你要用到的一些不同日期。

在使用本文中的例子之前，你必须注意以下的问题。大部分可能不是所有例子在不同的机器上执行的结果可能不一样，这完全由哪一天是一个星期的第一天这个设置决定。第一天（DATEFIRST）设定决定了你的系统使用哪一天作为一周的第一天。所有以下的例子都是以星期天作为一周的第一天来建立，也就是第一天设置为7。假如你的第一天设置不一样，你可能需要调整这些例子，使它和不同的第一天设置相符合。你可以通过@@DATEFIRST函数来检查第一天设置。

为了理解这些例子，我们先复习一下DATEDIFF和DATEADD函数。DATEDIFF函数计算两个日期之间的小时、天、周、月、年等时间间隔总数。DATEADD函数计算一个日期通过给时间间隔加减来获得一个新的日期。要了解更多的DATEDIFF和DATEADD函数以及时间间隔可以阅读微软联机帮助。

使用DATEDIFF和DATEADD函数来计算日期，和本来从当前日期转换到你需要的日期的考虑方法有点不同。你必须从时间间隔这个方面来考虑。比如，从当前日期到你要得到的日期之间有多少时间间隔，或者，从今天到某一天（比如1900-1-1）之间有多少时间间隔，等等。理解怎样着眼于时间间隔有助于你轻松的理解我的不同的日期计算例子。

一个月的第一天

第一个例子，我将告诉你如何从当前日期去这个月的最后一天。请注意：这个例子以及这篇文章中的其他例子都将只使用DATEDIFF和DATEADD函数来计算我们想要的日期。每一个例子都将通过计算但前的时间间隔，然后进行加减来得到想要计算的日期。

这是计算一个月第一天的SQL 脚本：

SELECT DATEADD(mm, DATEDIFF(mm,0,getdate()), 0)

我们把这个语句分开来看看它是如何工作的。最核心的函数是getdate()，大部分人都知道这个是返回当前的日期和时间的函数。下一个执行的函数DATEDIFF(mm,0,getdate())是计算当前日期和“1900-01-01 00:00:00.000”这个日期之间的月数。记住：时期和时间变量和毫秒一样是从“1900-01-01 00:00:00.000”开始计算的。这就是为什么你可以在DATEDIFF函数中指定第一个时间表达式为“0”。下一个函数是DATEADD，增加当前日期到“1900-01-01”的月数。通过增加预定义的日期“1900-01-01”和当前日期的月数，我们可以获得这个月的第一天。另外，计算出来的日期的时间部分将会是“00:00:00.000”。

这个计算的技巧是先计算当前日期到“1900-01-01”的时间间隔数，然后把它加到“1900-01-01”上来获得特殊的日期，这个技巧可以用来计算很多不同的日期。下一个例子也是用这个技巧从当前日期来产生不同的日期。

本周的星期一

这里我是用周(wk)的时间间隔来计算哪一天是本周的星期一。

SELECT DATEADD(wk, DATEDIFF(wk,0,getdate()), 0)

一年的第一天

现在用年(yy)的时间间隔来显示这一年的第一天。

SELECT DATEADD(yy, DATEDIFF(yy,0,getdate()), 0)

季度的第一天

假如你要计算这个季度的第一天，这个例子告诉你该如何做。

SELECT DATEADD(qq, DATEDIFF(qq,0,getdate()), 0)

当天的半夜

曾经需要通过getdate()函数为了返回时间值截掉时间部分，就会考虑到当前日期是不是在半夜。假如这样，这个例子使用DATEDIFF和DATEADD函数来获得半夜的时间点。

SELECT DATEADD(dd, DATEDIFF(dd,0,getdate()), 0)

深入DATEDIFF和DATEADD函数计算

你可以明白，通过使用简单的DATEDIFF和DATEADD函数计算，你可以发现很多不同的可能有意义的日期。

目前为止的所有例子只是仅仅计算当前的时间和“1900-01-01”之间的时间间隔数量，然后把它加到“1900-01-01”的时间间隔上来计算出日期。假定你修改时间间隔的数量，或者使用不同的时间间隔来调用DATEADD函数，或者减去时间间隔而不是增加，那么通过这些小的调整你可以发现和多不同的日期。

这里有四个例子使用另外一个DATEADD函数来计算最后一天来分别替换DATEADD函数前后两个时间间隔。

上个月的最后一天

这是一个计算上个月最后一天的例子。它通过从一个月的最后一天这个例子上减去3毫秒来获得。有一点要记住，在Sql Server中时间是精确到3毫秒。这就是为什么我需要减去3毫秒来获得我要的日期和时间。

SELECT dateadd(ms,-3,DATEADD(mm, DATEDIFF(mm,0,getdate()), 0))

计算出来的日期的时间部分包含了一个Sql Server可以记录的一天的最后时刻(“23:59:59:997”)的时间。

去年的最后一天

连接上面的例子，为了要得到去年的最后一天，你需要在今年的第一天上减去3毫秒。

SELECT dateadd(ms,-3,DATEADD(yy, DATEDIFF(yy,0,getdate()), 0))

本月的最后一天

现在，为了获得本月的最后一天，我需要稍微修改一下获得上个月的最后一天的语句。修改需要给用DATEDIFF比较当前日期和“1900-01-01”返回的时间间隔上加1。通过加1个月，我计算出下个月的第一天，然后减去3毫秒，这样就计算出了这个月的最后一天。这是计算本月最后一天的SQL脚本。

SELECT dateadd(ms,-3,DATEADD(mm, DATEDIFF(m,0,getdate())+1, 0))

本年的最后一天

你现在应该掌握这个的做法，这是计算本年最后一天脚本

SELECT dateadd(ms,-3,DATEADD(yy, DATEDIFF(yy,0,getdate())+1, 0))

本月的第一个星期一

好了，现在是最后一个例子。这里我要计算这个月的第一个星期一。这是计算的脚本。

select DATEADD(wk, DATEDIFF(wk,0,

dateadd(dd,6-datepart(day,getdate()),getdate())), 0)

-------------------------------------------------------------sql中根据字段不同sum统计

sum(case LeiBie when '阶段计划' then SL else 0 end) as 'JDSL',

------------------在某字段后面加字符是没有问题的

use cc

SELECT Name+'hhh',Sex,sum(Score) as 'ddd' from Score

GROUP BY Name,sex WITH ROLLUP

-----------------------------js依次打印文字；

it=0;

function typeit() {

var word = mytext.charAt(it, idstr);

if (it < mytext.length - 1) {

it++

t = setTimeout("typeit()", Math.random() * 10);

}

else {

clearTimeout(t);

it = 0;

i++;

start();

}

------------------------------js若在页面已加载就开始调用服务器端控件,对报关于对象的错！

解决方案，通过后台注册脚本方法间接调用前台方法；

-----js向标记中添加标记

累加$("#content").append("<img src='../img/bg2.jpg'/>");不累加：.html();

或者是js:.innerHTML=；累加：+=innerHTML;

----------------要让出链接之外的有北京颜色显示需要

$("li").mouseenter(function () {

$(this).attr("background-color", "#ccff66");

});

和

li:hover

{

/*background-image: url(img/menu2.gif);*/

cursor: pointer;

background-color:#ccff66;

}同时使用才有效果；

------------------------------frame去掉边框：

---------------------------------------------------------:

decimal(18,6);

-----------------------------虚拟表：#表名；

---timestamp:时间戳，二进制数据；

----WAITFOR delay '00:00:005'：数据库时间延迟

---SELECT @@rowcount;返回上一操作所影响的行数，如果大于0，可判断操作是否成功；

处理并发：悲观：（事务+锁）；乐观（时间戳）

悲观处理方式是采用SQLSERVER数据库中“事务+锁”！（隔离级别总共四种默认level1）会产生脏读；

　　先上伪代码再解释：

　　1.先解释2个要用到的锁

　　SELECT * FROM table WITH (HOLDLOCK) 其他事务可以读取表，但不能更新删除（避免不可重复读），避免统一事务多次读取结果一致防止他人修改；

　　SELECT * FROM table WITH (TABLOCKX) 其他事务不能读取表,更新和删除

　 SELECT * FROM table WITH (updLOCK) 其他事务能读取表,但不能更新

　　PS：这2个是表级锁，要锁行加上SQL过滤条件即可。数据库的默认隔离级别是readcommit,(更改的事务未完成，其它不能读取)

也就是level1;，可读：可以查询+with(holdlock),若想不可读，with(tablockx)

2.乐观：事务+时间戳；

------------------如何避免死锁 1 使用事务时，尽量缩短事务的逻辑处理过程，及早提交或回滚事务；

2 设置死锁超时参数为合理范围，如：3分钟-10分种；超过时间，自动放弃本次操作，避免进程悬挂；

3 优化程序，检查并避免死锁现象出现； 4 .对所有的脚本和SP都要仔细测试，在正是版本之前。

5 所有的SP都要有错误处理（通过@error） 6 一般不要修改SQL SERVER事务的默认级别。

不推荐强行加锁

------------------------------------时间戳：（微软建议用rowversion）

convert(bigint,time)，对应c#int64进行比较即可；

--------------------别面内存泄露的方法，在一个类中创建另一个类的实例时，当不用了，赋值null,这样就告诉系统，可以回收了；

------恢复数据库:

restore database guo from disk='路径备份' with recovery

------------------经典的dispose();垃圾回收gc（回收时将对象赋值为null）,告诉回收器，我已经不被引用了，随时清理；

class A:IDisposable

{

private bool isDisposed = false;

public void Dispose()

{

Dispose(true);

GC.SuppressFinalize(this);//告诉回收器清理已完成，无需调用析构函数；

}

protected virtual void Dispose(bool disposing)

{

if (!isDisposed)

{

if (disposing)

{

//释放托管资源

}

//释放非托管资源

}

isDisposed = true;

}

~A()//有回收期调用，不固定；

{

Dispose(false);

//主要清理非托管；

}

-------------------------------------文件流，数据库的连接，系统的窗口句柄，打印机资源等等网络连接，这些是非托管资源；

-----产生内存泄露的原因：

文件流，数据库的连接，系统的窗口句柄，打印机资源等等

未调用Dispose方法

使用不彻底的Dispose方法

在Windows Forms中对BindingSource的误用

未在WorkItem/CAB上调用Remove

------------

对象的创建者或拥有者负责销毁对象，而不是使用者

当不再需要一个事件订阅者时退订此事件，为确保安全可以在Dispose方法中退订

当对象不再触发事件时，应该将对象设为null来移除所有的事件订阅者

当模型和视图引用同一个对象时，推荐给视图传递一个此对象的克隆，以防止无法追踪谁在使用哪个对象

对系统资源的访问应该包装在using块中，这将在代码执行后强制执行Dispose

用上面的SQL语句还原备份数据库时，数据库的状态总是“正在还原”，使得不能对它进行其他操作。

解决方案：“RESTORE DATABASE " + dbName + " From disk='" + filePath + "' WITH REPLACE,RECOVERY ";

-----------一般还原数据库的话是 with replace;

----------------备份知识

1、SQL数据库恢复模型

----------------------------------------------------------------------

1）完全恢复模型

-----------------

（1）备份时要备份数据库的数据文件和日志文件

（2）还原时使用数据库的备份的数据文件副本和全部日志信息来恢复数据库。

（3）能还原全部数据，并可以将数据库恢复到任意指定的时刻。

（4）为保证实现即时点恢复，对数据库的所有*作都将完整地记入日志，这样，日志占用空间较大，对性能也有所影响。

------------------

（2）大容量日志记录恢复模型

------------------

（1）备份时要备份数据库的数据文件和日志文件

（2）还原时使用数据库的备份的数据文件副本和全部日志信息来恢复数据库。

（3）日志中不记录*作细节（如select into、create index等），而只记录*作的最终结果，因此占用日志空间小。

（4）只支持将数据库还原到事务日志备份的时刻，而不支持即时点恢复，因此可能产生数据丢失。

-------------------

（3）简单恢复模型

-------------------

（1）备份时只备份数据文件，还原时也用备份的数据文件恢复数据库。

（2）只能将数据恢复到数据文件备份的时刻，可能产生最多的数据丢失。

（3）不适于生产系统和大规模*作环境下选用。

-----------------------------------------

alter database d1 set recovery simple --设置数据库恢复模型

alter database d1 set recovery bulk_logged

alter database d1 set recovery full

----------------------------------------------------------------------

2、备份设备

----------------------------------------------------------------------

1）物理设备

---------------------------

disk：支持本地磁盘或者网络备份

tape：支持磁带机备份

name pipe：支持第三方备份软件

---------------------------

2）逻辑设备

---------------------------

永久备份文件：可以重复使用，应该在备份前创建。

临时备份文件：用于一次性备份，在备份时创建。

-------------------------------------------------

exec sp_addumpdevice 'disk','bak2','e:\back_device\bak2.bak' --创建永久磁盘备份设备

exec sp_addumpdevice 'disk','bak3','e:\back_device\bak3.bak'

----------------------------------------------------------------------

exec sp_addumpdevice 'disk','bak4','\\sv2\backup\bak4.bak' --创建网络永久磁盘备份设备

exec sp_addumpdevice 'disk','bak5','\\sv2\backup\bak5.bak'

----------------------------------------------------------------------

exec sp_dropdevice 'bak5' --删除备份设备

----------------------------------------------------------------------

backup database d3 to bak3 --将数据库备份到备份设备

backup database d4 to bak4

----------------------------------------------------------------------

restore headeronly from bak2 --查看备份设备中的内容

----------------------------------------------------------------------

backup database d3 to disk='e:\back_file\d3.bak' --将数据库备份到临时备份文件

backup database d4 to disk='e:\back_file\d4.bak'

----------------------------------------------------------------------

restore database d3 from bak3 --从备份设备还原数据库

restore database d4 from disk='e:\back_file\d4.bak' --从备份文件还原数据库

----------------------------------------------------------------------

3、使用多个备份文件存储备份

----------------------------------------------------------------------

1）SQL可同时向多个备份文件进行写*作。如果把这些文件放到多个磁带机或磁盘中，则可提高备份速度。

2）这多个备份文件必须用同业型的媒体，并放到一个媒体集中。

3）媒体集中的文件必须同时使用，而不能单独使用。

4）可以通过format命令将媒体集重新划分，但原备份集中的数据不能再使用。

--------------------------------------------------------------------

backup database d4 to bak4,bak5,bak6 with medianame='bak456',format --备份D4并形成Media Set

backup database d3 to bak4 --失败，因Media set中文件必须同时使用

backup database d3 to bak4,bak5,bak6 --成功，将D3也备份到Media Set中

restore headeronly from bak4,bak5,bak6--查看Media Set中的备份内容

----------------------------------------------------------------------

backup database d4 to bak4 with medianame='bak4',format --重新划分Media Set

backup database d3 to bak5,bak6 with medianame='bak56',format

----------------------------------------------------------------------

backup database d1 to bak1 with init --with init重写备份设备中内容

backup database d2 to bak1 with noinit --with noinit将内容追加到备份设备中

restore headeronly from bak1

----------------------------------------------------------------------

4、备份的方法

----------------------------------------------------------------------

1）完全备份

-------------------------------------------

（1）是备份的基准。在做备份时第一次备份都建议使用完全备份。

（2）完全备份会备份数据库的所有数据文件、数据对象和数据。

（3）会备份事务日志中任何未提交的事务。因为已提交的事务已经写入数据文件中。

--------------------------------------------

backup database d1 to bak1 with init --完全备份

backup database d1 to bak1 with noinit

----------------------------------------------------------------------

2）差异备份

---------------------------------------------

（1）基于完全备份。

（2）备份自最近一次完全备份以来的所有数据库改变。

（3）恢复时，只应用最近一次完全备份和最新的差异备份。

-----------------------------------------------

backup database d2 to bak2 with init,name='d2_full' --差异备份，第一次备份时应做完全备份

create table b1(c1 int not null,c2 char(10) not null)

backup database d2 to bak2 with differential,name='d2_diff1'

insert b1 values(1,'a')

backup database d2 to bak2 with differential,name='d2_diff2'

insert b1 values(2,'b')

backup database d2 to bak2 with differential,name='d2_diff3'

insert b1 values(3,'c')

backup database d2 to bak2 with differential,name='d2_diff4'

restore headeronly from bak2

----------------------------------------------------------------------

3）事务日志备份

-------------------------------------------------------------

（1）基于完全备份。

（2）为递增备份，即备份从上一次备份以来到备份时所写的事务日志。

（3）允许恢复到故障时刻或者一个强制时间点。

（4）恢复时，需要应用完全备份和完全备份后的每次日志备份。

-------------------------------------------------------------

backup database d3 to bak3 with init,name='d3_full' --日志备份，第一次备份时应做完全备份

create table b1(c1 int not null,c2 char(10) not null)

backup log d3 to bak3 with

insert b1 values(1,'a')

backup log d3 to bak3 with

insert b1 values(2,'b')

backup log d3 to bak3 with

insert b1 values(3,'c')

backup log d3 to bak3 with

restore headeronly from bak3

----------------------------------------------------------------------

create table b1(c1 int not null,c2 char(10) not null) --Full+Log+Diff

backup log d4 to bak4 with

insert b1 values(1,'a')

backup log d4 to bak4 with

insert b1 values(2,'b')

backup database d4 to bak4 with differential,name='d4_diff1'

insert b1 values(3,'c')

backup log d4 to bak4 with

insert b1 values(4,'d')

backup log d4 to bak4 with

insert b1 values(5,'d')

backup database d4 to bak4 with differential,name='d4_diff2'

restore headeronly from bak4

----------------------------------------------------------------------

日志清除

-----------------------------------------

1）如果日志空间被填满，数据库将不能记录修改。

2）数据库在做完全备份时日志被截断。

3）如果将'Trans log on checkpoint'选项设为TRUE，则结果为不保存日志，即没有日志记录，不建议使用。

4）with truncate_only和with no_log设置日志满时清除日志

5）with no_truncate则可以完整保存日志，不清除，即使在数据文件已经损坏情况下。主要用于数据库出问题后在恢复前使用。可以将数据还原到出故障的那一时刻。

-------------------------------------------

exec sp_dboption d3

exec sp_dboption

sp_dboption 'd3','trunc. log on chkpt.','true' --设置自动清除数据库日志

sp_dboption 'd3','trunc. log on chkpt.','false' --将自动清除数据库日志的选项去除

----------------------------------------------------------------------

backup log d4 with truncate_only --设置D4日志满时清除日志，并做清除记录

----------------------------------------------------------------------

backup log d4 with no_log --设置D4日志满时清除日志，但不做清除记录

----------------------------------------------------------------------

backup log d4 to bak4 with no_truncate--在D4数据库损坏时马上备份当前数据库日志(DEMO)

--------

使用no_truncate

完全+修改1+差异+修改2+差异+修改3+停止SQL，删除数据库数据文件+重启SQL

backup log no_truncate

再还原，可还原到修改3

-----------------------------数据库恢复顺序；

恢复数据库中的数据，所以通常恢复的时间较长；先恢复最后一次全库备份，再恢复最后一次差异备份，

再顺序恢复最后一次差异备份以后进行的所有事务日志备份

------------------数据库四种备份；

1）完全数据库备份

完全数据库备份是备份数据库的所有表的数据及模式，以及对应的文件结构，包括对事务日志中的事务进行备份。它可以用作系统出现故障时恢复数据库的基础，也可用于在另外一台计算机上生成数据库的副本。

（2）差异数据库备份

差异数据库备份只记录自上次完全数据库备份后发生变化的数据。差异备份的数据量比完全备份的数据量小而且备份速度快，因此可以更经常地备份。

（3）事务日志备份

事务日志包含了自上次进行完全数据库备份、差异数据库备份或事务日志备份以来所完成的事务。可以使用事务日志备份将数据库恢复到特定的即时点或恢复到故障点。

（4）数据库文件和文件组备份

只备份特定的文件或文件组，常用于超大型数据库的备份。

---------------------------------------------------------数据并发，其多个用户修改其它用户正在使用的资源，并产生了一定的影响；

level0:(read uncommitted)；修改未提交时，便可以读取；---导致脏读；解决方案：SET tran isolation level read uncommitted

个事务读到另外一个事务还没有提交的数据，我们称之为脏读

level1(read committed):(sql默认，(修改的过程中不允许读和修改)修改时(修改的进程还没结束)，另一进程不能读取)read committed;---导致不可重复读：解决方案:读取的事务中设置SET tran isolation level repeatable read;

一个事务先后读取同一条记录，但两次读取的数据不同，我们称之为不可重复读。读取的过程中（5秒钟内），有其它事务修改了数据；

level2:（repeatable read）,{原理：进行了s锁，作用（小于with(holdlock),因为，le2不允许修改，所以不会出现不可重复读，但出现幻读，可以插入，而holdlock不允许，这就是区别）

}解决方案：set tran isolation level serializable;:串行化（个人认为是holdlock原理）：

一个事务先后读取一个范围的记录，但两次读取的纪录数不同，我们称之为幻象读；（幻读，读的时候有数据插入，不可重复读，读的时候有数据修改）

level3:(serializable)串行化:避免了幻读；

-------更改隔离类别；

BEGIN transaction

SET tran isolation level read uncommitted

update -----

IF @@error=0

COMMIT transaction

else

ROLLBACK transaction

-------------------------------默认的level1:在修改中不允许修改和查询，单允许插入；（插入不会引起不一致和完整性）

----------with(holdlock):查询时，不允许修改和插入操作，允许查询；

----------with(tablockx):查询时什么都不允许；

-------------------这两个锁只能应用在查询上；

总结

事务隔离级别是通过数据库的锁机制来控制的，在不同的应用场景需要应用不同的事务隔离级别，

SQL Server默认的事务隔离级别是READ COMMITTED，默认的隔离级别，已经可以满足我们大部分应用的需求。

--------------------------行级锁：锁的粒度小；不想表级锁，updlock,告诉大家，标记我整个事务将要更改，你们不要进行操作；

});

--------------

$("li:eq(3)").css("background-color", "red");匹配第四个li;

--------------not:除此之外的；

$("li").not($("li:last")).css("background-color", "red");

-------------2,3只选择第三个，2,4只选择第三和第四个，索引从0开始；当slice(2),表示从第三个到最后一个；

$("li").slice(2，3).css("background-color", "red");

---------------------lt:前四个；

$("li:gt(4)").css("background-color", "red");

-------所有的li;

$("ul").children().css("background-color", "red");

--------class为dd的类；

-------------所有的同级元素；

$("#f").nextAll().css("background-color", "red");

-----------挨着的第一个同级元素；

$("#f").next().css("background-color", "red");

-----------同级直到table标记之间的同级标记，不包括table;

$("#f").nextUntil("table").css("background-color", "red");

-------------找到所有父级的标记；

$("#nei").parents().css("background-color","red");

-------------应该只有上一级；

$("#nei").parent().css("background-color","red");

-------------

siblings:除此之外的所同级元素；

---------相当于累加；

$("#nei").add("table").add("#f").css("background-color","red");

-----------并把自己也加上；

$("div").find("p").andSelf().addClass("border");

--------------将所有元素添加到b标签中；

$("#nei").contents().wrap("<b/>");

-------------在p标签的前面添加标记；append是后面；

$("p").prepend("<b>Hello</b>");

--------------.after,.before,insertafter,insertbefore;

------------将元素包含到另一元素中；

$("p").wrap(document.getElementById('content'));

------------

将所有匹配的元素用单个元素包裹起来时使用wrapall();

---------------------------:在p的内部添加b;(将b的内容用b抱起来)

$("p").wrapInner("<b></b>");

-----------变换标记；

$("p").click(function () {

$(this).replaceWith("<img src='../img/_8-1.png'></img>");

-----------

});

---------------------复制一份添加到标记中

$("b").clone().prependTo("p");

---------------------

将所有段落的字体颜色设为红色并且背景为蓝色。

jQuery 代码:

$("p").css({ color: "#ff0011", background: "blue" });描述:

如果属性名包含 "-"的话，必须使用引号:

jQuery 代码:

$("p").css({ "margin-left": "10px", "background-color": "blue" });

-----------------------不管怎么样：键值都加双引号；

$("#f").css({"color":"red","background":"blue"});

----------------------------------------------------------offset相对document的位置；

-----------设定移量；

$("#xuan").offset({top:200,left:400});

-------------得到相对位置

var a = $("#xuan").offset();

alert(a.left+"----"+a.top);

--------------------------------------------------------------position(),相对于父元素的偏移量；用法和offset一样；

------blur():失去焦点触发的事件；

-----change()事件:当内容改变且失去焦点时触发；

-------------滚动条滚动

$(window).scroll(function () {

setTimeout();

});

-----------序列化操作：

var a = $.parseJSON('{ "name": "guozeng" }');

alert(a.name);

});

$("li").click(function () {

$("#Text1").val($(this).text());

$("#gg").css("display", "none");

});

})

$(function () {

$("img[alt='a']").click(function () {

if ($(this).attr("src") == "../img/_8-1.png") {

$(this).attr("src", "../img/_8-2.png")

$("#gg").slideUp(500);

$(this).attr("src", "../img/_8-1.png")

$("#gg").slideDown(500);

}

});

})

------------------------------------------------------------------------------------------------------------------

1.new 父类方法：相当于复制了父类的方法，通过比对，不是重写，所以没有记录到方法表的重写表上。当父类引用指向子类实例时，调用该方法先去重写表上找，如果没找到，说明没被重写，所以继续调用父类的方法；

2.继承，实际上是：先将父类复制一份分配内存，在和子类比对，将重写的方法写在loader heap的方法表上，当父类指向子类实例，先检查方法表是否存在重写方法，没有的话，继续调用父

类的。

3,栈：从高位到低位，控件有限，堆，从低位到高位，回收时，无论栈还是堆，都从低位开始回收，所有就有的先进先出，先进后出之分；

4.进程栈，托管堆：gc堆，存储属性，loader heap:存储方法表、静态变量;生命周期：appdomain结束（应用程序域结束），当>85K时，存在loh上（large object heap）

5.类的静态放在loader heap上，先于实例创建。属性，无论引用还是值都创建在堆上。方法里的值创建在进程栈上。值类型中的引用对象的创建，还保持原来一样，引用在栈，创建在堆上。

-----------------------------------------------

1：不管是重写还是覆盖都不会影响父类自身的功能（废话，肯定的嘛，除非代码被改）。

2：当用子类创建父类的时候，如 C1 c3 = new C2()，重写会改变父类的功能，即调用子类的功能；而覆盖不会，仍然调用父类功能。

3：虚方法、实方法都可以被覆盖（new），抽象方法，接口不可以。

4：抽象方法，接口，标记为virtual的方法可以被重写（override），实方法不可以。

5：重写使用的频率比较高，实现多态；覆盖用的频率比较低，用于对以前无法修改的类进行继承的时候。

----------------

Thread类有几个至关重要的方法，描述如下：

Start()：启动线程；

Sleep(int)：静态方法，暂停当前线程指定的毫秒数；

Abort()：通常使用该方法来终止一个线程；

Suspend()：该方法并不终止未完成的线程，它仅仅挂起线程，以后还可恢复；

Resume()：恢复被Suspend()方法挂起的线程的执行；

------只要是聚合函数就可以用case when;group by 后面可以加t-sql函数；

SELECT count(CASE WHEN CContent>4 THEN NULL ELSE 1 END) FROM DailyCheckRecord GROUP BY datepart(year,CDate)

--------------------------

select count(0):查询结果为1；

----------------------------------------(1):

[ServiceContract(Name = "name_IUser", Namespace ="http://localhost:3232/wpf/aa")]

-------------------------------------------(2)

[OperationContract(Name = "name_GetName", Action = "http://localhost:3232/wpf/aa/ServiceContract/GetName")]

--------------------------------(3)

using System.Runtime.Serialization;//datacontract；由此而来；需要添加引用的

--------------------李氏替换；不会剖出异常；

//[KnownType(typeof(DataItem.SonDataUser))]；(体现的是一种多态行处理)

------------------------（4）

//isrequired:是否必须初始化；order；序列化时顺序；

[DataMember(Name="name_Name",IsRequired=false,Order=0)]

----------------------------------------------------------

object.Equals("0001/1/1 0:00:00", DateTime.MinValue.ToString()

-----------------------------------------------------------------------

property与attribute的区别：

property:有getset;button按钮的宽度和高度；

attribute:比如：[serializable]

---------------------------------------------------------调用web服务生成成一步操作：必须这样：（异步调用）

protected void Button1_Click(object sender, EventArgs e)

{

ServiceReference1.WebServiceSoapClient a = new ServiceReference1.WebServiceSoapClient();

a.HellowAsync(new ServiceReference1.HellowRequest(new ServiceReference1.HellowRequestBody(1)));

a.HellowCompleted += new EventHandler<ServiceReference1.HellowCompletedEventArgs>(a_HellowCompleted);

}

public void a_HellowCompleted(object sender, ServiceReference1.HellowCompletedEventArgs e)

{

TextBox1.Text ="sff";

}

------------------同步调用：

ServiceReference1.WebServiceSoapClient a = new ServiceReference1.WebServiceSoapClient();

//ServiceReference1.HellowResponse aa = a.Hellow(new ServiceReference1.HellowRequest(new ServiceReference1.HellowRequestBody(2)));

//MessageBox.Show(aa.Body.HellowResult.ToString());

------------------------------------------------------------------------

if ($("#RadioButton1").attr("checked") ==true) {

alert("郭泽峰呢个");

}

------------------------jquery获取dropdownlist的值；

alert($("#dropProperty").find('option').filter(':selected').text());

var chec kText=$("#select_id").find("option:selected").text(); //获取Select选择的Text

-----------

if ($("#RadioButton1").attr("checked") == true) {

isBid = "是";

}

------------------------js截取字符串；

var param = hrefStr.substring(hrefStr.indexOf('?') + 1, hrefStr.length);

-------------

var aa = $("a[href='/AjaxPaging/UpdataModel/" + hdnId + "']").parent().parent().find("td");

$(aa).slice(0, 1).text(name);

------------------------进程的Process的命名空间（using System.Diagnostics;）意思是诊断的意思；

var ff = new Function("p1", "alert(p1)");

ff(2);

---------------------------

for(var a in arr)

{

alert(a);

}

--------------w3c标准事件；（Ie不支持，其它支持）(注意两个地方不一样；)

document.addEventListener("click", f1);

-------------ie;

document.attachEvent("onclick",f1);

------------

window.event.clientX,clientY;鼠标在文档的位置；

window.event.screenX,screenY;鼠标在浏览器的位置；

window.event.offsetX,offsetY;相对于事件源的位置；

window.event.returnValue=false;取消默认行为；如提交按钮不会提交；

----------------取消事件冒泡：

window.event.cancelBubble=true;

-----------动态创建：

window.onload = function () {

var btn = document.createElement("input");

btn.name = "guo";

btn.type = "button";

btn.onclick = function () {

alert("我去你大爷");

};

btn.value = "动态创建";

var dv = document.getElementById("mm");

dv.appendChild(btn);

};

------------document.getelementbyid("").style.background="";

------------

onload与onready的区别：

onload,等documnet和css,js外部文件加载完之后才执行；只能注册一次；

ready:只等document加载完毕之后才执行；可注册多此；可以提高响应速度；

----------

map:对数组遍历；

each:对字典的遍历；

---------------------

// $.each(person, function (key, value) {

// alert(key+"--"+value);

> // }, null);

$.each(person, function () {alert(this) });//this，指的是值，因为我们更对值感兴趣；

=--------------\.next("div"):紧邻的第一个；如果没挨着；放回空；

-----。end（）,方法返回上一次被破坏的包装集，比如：$("#id").nextall().end(),指的是$("#id")

$("#id").next().andSelf()//报错自己和挨着的；

------去掉第一行：

$("#id tr:not(:first)");去掉第一行；

$("#id tr:not(:first):not(:last):even");各行设置；

-----------------全选；

$("#checkall").click(function () {

$(":checkbox[id*=checkbox]").attr("checked", $(this).attr("checked"));

});

---------------------------05594054 0371

---动态创建子元素；

var a=$("<a href='sdf'></a>")

a.css();

a.click();

$().append(a);

----------------remove：会移除对象的事件，但不会移除对象的样式；

appendto();就相当于剪切粘贴；

----------$("#id").unbind();移除所有的事件；

.one("click",function(){});注册一次性事件，用完后随即unbind();如果没有参数，就卸载所有的事件；

--------------------------------------------

$("#Button1").bind("click", function () {

alert(1);

});

$("#Button1").unbind("click");

-----------------------------------------------切换事件；第一次点击显示1，第二次显示2；

$("#Button1").toggle(function () { alert(1)}, function () { alert(2) });

--------------事件参数可以防止事件冒泡；

$("#id").click(function(e){

alert("郭");

e.stopPropagetion();

});

这样在id之外的标签事件就不会触发；

$("#id").click(function(e){

alert("郭");

e.preventDefault();//取消控件的默认行为；与return false;不同的是，后续代码继续执行；比如取消连接的跳转功能；

alert("则");

});

-------------------

$(document).mousemove(function(e){

$("#di").text(e.pageX+"=="+e.pageY);//获取文档的坐标；

});

----------

$(document).mousemove(function(e){

$("#di").css({"left":e.pageX,"top":e.pageY});//获取文档的坐标；

});

-----------------扩展方法：

$.extend({ "max": function (a, b) {

if (a > b)

return a;

}, "min": function () {

if (a < b)

return a;

}

------------------扩展实例方法：

$.fn.extend({"checked":$(this).attr("checked","true")});

$(function () {

alert($.max(55,34));

})

------调用： $("").checked();

----------------------------------

$(window).width();

----------------------cookie:(需要引入cookie.js)

$.cookie("name",value,{expires=10})

----------------------------------frame;

window.parent.afterEdit();

var childWindow = $("#frameEdit")[0].contentWindow; //怎么来拿frame标签的一个window对象

childWindow.submitEditFrm();

---------------------数据绑定；gridview;

DataBinder.Eval(Container.DataItem,"Id")

--------------------------------------------------引用样式表；css嵌套引用另一个css文件；

@import url(cs1.css);

-------------------------

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<asp:PostBackTrigger ControlID="btnExport" />

</Triggers>

------------------------------------------必须这样：

if (!object.Equals(reader["BidDate"], null) && !object.Equals(reader["BidDate"],DBNull.Value))

或

if (!object.Equals(reader["BidDate"], null) &&reader["BidDate"].tostring()!="")

-------------------------------------------------------------------

类的。

3,栈：从高位到低位，控件有限，堆，从低位到高位，回收时，无论栈还是堆，都从低位开始回收，所有就有的先进先出，先进后出之分；

4.进程栈，托管堆：gc堆，存储属性，loader heap:存储方法表、静态变量;生命周期：appdomain结束（应用程序域结束），当>85K时，存在loh上（large object heap）

---------------------------当有输出参数执行字符串时；

EXEC sp_executesql @str, N'@num INT OUTPUT', @num OUTPUT

-------------行列转换

SUM(CASE WHEN T.ParentName=''休假'' THEN T.alldays ELSE 0 END)

--------------------------js根据出生日期获取年龄；

$(function () {

$("#txtAge").click(function () {

var dateUser = new Date();

var nowYear = dateUser.getFullYear();

var dateUser1 = new Date($("#txtBirthDate").val());

var birthYear = dateUser1.getFullYear();
