问题描述

我正在将存储过程从SQL Server转换为Oracle.此存储过程提供了直接结果集.我的意思是，如果您在例如Management Studio中调用存储过程，则可以直接获取结果集.

I'm working on converting a stored procedure from SQL server to Oracle.This stored procedure provides a direct resultset. I mean that if you call the stored procedure in eg Management Studio you directly obtain the resultset.

通过转换为Oracle，我克服了我在Oracle中不会显示结果集的问题

By converting to Oracle I walk against the problem that I in Oracle will not display the resultset

我在Internet上进行搜索，发现存储过程应该产生一个REF CURSOR，但是我仍然不满要编写一些代码来获取处理过程中的结果集的问题.

I searched on the Internet and have seen that the stored procedure should yield a REF CURSOR, but I still walk with the problem to write a little piece of code to obtain the resultset en process that.

伪代码:

调用存储过程并获取游标使用该光标进行操作，以便显示我的结果集

Call stored procedure and obtain cursorDo something with that cursor so that my resultset appears

有人有主意吗?

推荐答案

在SQL Plus中:

In SQL Plus:

SQL> create procedure myproc (prc out sys_refcursor)
  2  is
  3  begin
  4     open prc for select * from emp;
  5  end;
  6  /

Procedure created.

SQL> var rc refcursor
SQL> execute myproc(:rc)

PL/SQL procedure successfully completed.

SQL> print rc
