这段时间晚上有时候去打打球，回家看看电视剧，日子一天天过……。学了点ORACLE存储过程基础，作一下备注，以便日后需查阅。
创建无参存储过程
create procedure p_myPro1 is
begin
insert into dept(deptno,dname,loc) values(60,'ccx','');
end;
修改无参存储过程
create or replace procedure p_myPro1 is
begin
insert into dept(deptno,dname,loc) values(60,'ccx','');
end;
创建和修改有参存储过程
create or replace procedure p_myPro2(spName varchar2,newSal number) is
begin
update emp set sal=newSal where ename=spName;
end; call p_myPro2('SCOTT','');
创建和修改有参存储过程 带反回值
create or replace function f_myPro3(spName varchar2)
return number is
yearSal number(7,2);
begin
select sal*12 into yearSal from emp where ename=spName;
return yearSal;
end;
调用方法：select f_mypro3('SCOTT') from dual;
查看错误信息
show error;
调用存储过程
调用存储过程的方式有两种，call,exec
exec是sqlplus的命令，只能在sqlplus中使用。和 set serveroutput on 一起用。call是sql命令，任何工具都可以使用。
例如：call p_myPro1()
Oracle输出语句过程
dbms_output是oracle所提供的包(类似java的开发包)，该包包含一些过程，put_line就是dbms_output包的一个过程。
Oracle变量的使用例子
declare
v_ename varchar2(5);
v_sal number(7,2);
begin
select ename,sal into v_ename,v_sal from emp where empno=7369;
dbms_output.put_line('姓名'||v_ename||' 工资'||v_sal);
end;
Oracle异常捕捉
declare
v_ename varchar2(5);
v_sal number(7,2);
begin
select ename,sal into v_ename,v_sal from emp where empno=1111;
dbms_output.put_line('姓名'||v_ename||' 工资'||v_sal); exception
when no_data_found then
dbms_output.put_line('SELECT INTO没有找到数据');
when not_logged_on then
dbms_output.put_line('没有连接到ORACLE'); end;
