SQL Server 中查看加密的存储过程、函数,视图,触发器_9栋108的博客- -,第1张

今天在从SQL Server 2000 中导出数据库结构和数据的时候,出现了一个错误:do.[proc_GetNewPoNo] 是加密存储过程。SQL Server 2000 中不支持加密存储过程。

顾名思义该存储过程已经加密了,需要解密,在网上搜索了一下,运行,直接通过。

代码如下:

SET QUOTED_IDENTIFIER ON 
GO
SET ANSI_NULLS ON 
GO

CREATE PROCEDURE proc_decrypt(@objectname varchar(50))
AS
begin
set nocount on
--破解字节不受限制,适用于SQL SERVER 2000 存储过程,函数,视图,触发器
--修正上一版"视图触发器"不能正确解密错误
--

GO
SET QUOTED_IDENTIFIER OFF

SET ANSI_NULLS ON

创建成功后,需要:

EXEC proc_decrypt XXX -- 你的存储过程名称、函数名称、视图名称、触发器名称
