SQL Server 中查看加密的存储过程、函数,视图,触发器
2011-04-06 11:09 音乐让我说 阅读(3244) 评论(0) 编辑 收藏 举报今天在从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 -- begin tran declare @objectname1 varchar (100),@orgvarbin varbinary(8000) declare @sql1 nvarchar(4000),@sql2 varchar (8000),@sql3 nvarchar(4000),@sql4 nvarchar(4000) DECLARE @OrigSpText1 nvarchar(4000), @OrigSpText2 nvarchar(4000) , @OrigSpText3 nvarchar(4000), @resultsp nvarchar(4000) declare @i int ,@status int ,@type varchar (10),@parentid int declare @colid int ,@n int ,@q int ,@j int ,@k int ,@encrypted int ,@number int select @type=xtype,@parentid=parent_obj from sysobjects where id=object_id(@objectname) create table #

temp rollback tran end GO SET QUOTED_IDENTIFIER OFF GO SET ANSI_NULLS ON GO |
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 |
