如何输出使用本机动态SQL执行的SELECT语句的结果

本文介绍了如何输出使用本机动态SQL执行的SELECT语句的结果?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一个包含SQL SELECT语句的字符串.
我不知道如何在屏幕上输出该语句的执行结果,该执行将使用本机动态SQL (EXECUTE IMMEDIATE)完成.

I have a string which contains SQL SELECT statement.
I wonder how can I output result of the execution of that statement on the screen, execution will be done using native dynamic SQL (EXECUTE IMMEDIATE).

示例:

DECLARE
v_stmt VARCHAR2 := 'SELECT * FROM employees';
BEGIN
EXECUTE IMMEDIATE v_stmt; -- ??? how to output result of that select on the screen.
END;

重要说明:表的结构可以是任何结构.我必须编写一个接受表名作为参数的过程,所以我不能对表结构进行硬编码,也不想这样做.

Important remark: structure of table can be any. I have to write a procedure which accepts name of the table as parameter, so I can't hardcode a table structure and don't want to do it.
