1，create databse cookbook
2,给数据库cookbook创建一个用户burness，密码为123456
grant all on cookbook.* to ‘burness’on ‘localhost’ identified by ‘123456’
3,生成一个备份
mysqldump –h localhost –u burness –p cookbook > cookbook.sql
生成的cookbook.sql内容如下：

4,mysql从文件中读取语句
mysql cookbook < filename
eg：mysql cookbook < limbs.sql
limbs.sql内容如下：

drop table if exists limbs;
create table limbs
( thing varchar(20),
legs int,
arms int
);insert into limbs (thing,legs, arms) values(‘human‘,2,2);
insert into limbs (thing,legs, arms) values(‘insect‘,6,0);
insert
into limbs (thing,legs, arms) values(‘squid‘,0,10);
insert
into limbs (thing,legs, arms) values(‘octopus‘,0,8);
insert
into limbs (thing,legs, arms) values(‘fish‘,0,0);
insert
into limbs (thing,legs, arms) values(‘centipede‘,100,0);
insert
into limbs (thing,legs, arms) values(‘table‘,4,0);
insert
into limbs (thing,legs, arms) values(‘armchair‘,4,2);
insert
into limbs (thing,legs, arms) values(‘phonograhp‘,0,1);
insert
into limbs (thing,legs, arms) values(‘tripod‘,3,0);
insert
into limbs (thing,legs, arms) values(‘Peg Leg Pete‘,1,2);
insert
into limbs (thing,legs, arms) values(‘space alien‘,NULL,NULL);

或者使用source ，eg ： source test.sql
5，mysql还能使用pipe使用程序的查询命令
6，输出重定向：-H -X可以生成HTML，XML内容
mysql -u burness –p cookbook -e “select * from limbs where legs=0” >1.txt
mysql –H -u burness –p cookbook -e “select * from limbs where legs=0” >1.html
mysql –X -u burness –p cookbook -e “select * from limbs where legs=0” >1.xml
7,当过长的查询输出到屏幕需要一行来垂直地显示输出使用\G代替；
select * from limbs\G
8，记录交互式的mysql对话
mysql –u burness –p cookbook --tee=tmp.out cookbook
\T tmp.out
记录的命令及显示会输出到tmp.out
\t来停止记录
tmp.out 内容如下:

9，在mysql中使用自己定义的变量
@ var_name : value
eg: select @id := cust_id from customers where cust_id=’customer name’;
delete from orders where cust_id=@id;
delete from custers where cust_id=@id;
