恢复
dbcc addextendedproc ("sp_oacreate","odsole70.dll")
dbcc addextendedproc ("xp_cmdshell","xplog70.dll")

这样可以直接恢复，不用去管sp_addextendedproc是不是存在

-----------------------------

删除扩展存储过过程xp_cmdshell的语句:
exec sp_dropextendedproc 'xp_cmdshell'

恢复cmdshell的sql语句
exec sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'

开启cmdshell的sql语句

exec sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'

判断存储扩展是否存在
select count(*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell'
返回结果为1就ok

恢复xp_cmdshell
exec master.dbo.addextendedproc 'xp_cmdshell','xplog70.dll';select count(*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell'
返回结果为1就ok

否则上传xplog7.0.dll
exec master.dbo.addextendedproc 'xp_cmdshell','c:/winnt/system32/xplog70.dll'
