oracle存储过程基本语法学习入门必备
1.基本结构 
create or replace procedure存储过程名字 
( 
参数1 in number, 
参数2 in number 
) is 
变量1 integer :=0; 
变量2 date; 
begin 
end 存储过程名字 
2.select into statement 
将select查询的结果存入到变量中,可以同时将多个列存储多个变量中,必须有一条记录,否则抛出异常(如果没有记录抛出no_data_found) 
例子: 
  begin 
select col1,col2 into 变量1,变量2 from typestruct where xxx; 
exception 
when no_data_found then 
   xxxx; 
end; 
... 
3.if 判断 
if v_test=1 then 
    begin 
 do something 
    end; 
end if; 
4.while 循环 
while v_test=1 loop 
begin 
 xxxx 
end; 
  end loop; 
5.变量赋值 
v_test := 123; 
6.用for in 使用cursor 
  ... 
  is 
cursor cur is select * from xxx; 
  begin 
 for cur_result in cur loop 
  begin 
 v_sum :=cur_result.列名1+cur_result.列名2 
  end; 
 end loop; 
end; 
7.带参数的cursor 
  cursor c_user(c_id number) is select name from user where typeid=c_id; 
  open c_user(变量值); 
loop 
fetch c_user into v_name; 
exit fetch c_user%notfound; 
 do something 
  end loop; 
close c_user; 
8.用pl/sql developer debug 
连接数据库后建立一个test window 
在窗口输入调用sp的代码,f9开始debug,ctrl+n单步调试
