之前在帖子  里回答了一些网友的关于怎么穿件一个返回记录集合的存储过程。想必很多网友已经很明白了,这里就不多讲了。

怎么调用含游标的存储过程在sqlplus

Oracle怎么执行带游标的过程?

给你一个例子

--游标使用(游标其实是一个放入内存临时表)
declare
   money cms3_simcard.card_fee%type :=0; --定义与表字段相同类型
   cursor mycursor is --定义游标
          select * from cms3_simcard
          where return_flag = 1 and msisdn like '138%';
   my_record mycursor%rowtype;  --定义游标记录类型
   Counter int :=0;
  
begin
   open mycursor;  --打开游标
   if mycursor%isopen  then  --判断打开成功
   loop --循环获取记录集
     fetch mycursor into my_record; --获取游标中的记录
         if mycursor%found then  --游标的found属性判断是否有记录
            dbms_output.put_line(my_record.card_fee);
         else
            exit;
         end if;
   end loop;
   else
     dbms_output.put_line('游标没有打开');
   end if;
  close mycursor;
end;

如果你要问我程序里怎么调用 那你就不要问了 因为那个太多知道了 很少有人问到。 废话不多说 上实例了

首先看下t1的表结构

看下T1的表里的数据情况

和上一个帖子一样 首先创建一个包先

创建一个带游标的的存储过程也就是一个返回记录集合的存储过程

该有的数据都有了,,接着重点来了。  调用存储过程返回记录集合
