错误2812：未能找到存储过程 ‘master.dbo.xp_regread’

在还原数据库的时候出现"错误2812:未能找到存储过程'master.dbo.xp_fileexist'",

分析原因:这是因为某个出于安全考虑把系统扩展存储过程所有的动态连接库都删了

通过搜索查询到下面的解决方

法

解决方法：1、

把恢复数据库需要用到的存储过程个恢复,打开MSSQL查询分析器,分别运行下面的两条数据库语句即可.

EXEC sp_addextendedproc xp_dirtree ,@dllname ='xpstar.dll'

EXEC sp_addextendedproc xp_fileexist ,@dllname ='xpstar.dll'

解决方法：2、

重装SQL2000 SQL server 危险存储过程删除与恢复

就是在选择还原设备的时候直接把你的备份数据库的文件的路径填进去,点确定点确定后还是"错误2812:未能找到存储过程'master.dbo.xp_fileexist'",这时候你直接点这个错误对话框的确定按钮即可，然后选择：强制还原数据库,点开始还原数据库等一会就OK了

这是SQL自带的存储过程，在master的存储过程里，可以用以下语句重建，或者重装SQL，记得做好备份工作。

GO

第一：你的检查一下你的数据库中是否存在该存储过程，

第二：如果有的话，检查代码是否正确

第三：代码如果没问题，在数据库中执行该存储过程

第四：在数据库中如果可以执行的话，说明存储过程没问题，

这时不妨修改一下存储过程的名字，看是否还有错
