SQL Server中修改对象所有者的两种方法

一般开发，SQL Server的数据库所有者为dbo。但是，为了安全，有时候可能把它换成其它的名称。所有者变换不是很方便，这里列出两种供参考。

方案一：更改权限以添加HHRC用户

1、添加第三方用户，如“chn”；
2、运行sql，加对象权限移至第三方用户；
3、添加hhrc用户；
4、运行sql，将对象权限移至hhrc用户。

declare @tblname varchar(30)declare @tblown varchar(50)declare tbl_cur cursor for select name from sysobjects where uid="5" and status>=0 and xtype in ("U","P")--select * from sysusersopen tbl_curfetch next from tbl_cur into @tblnamewhile @@fetch_status=0beginset @tblown="web56433."+@tblnameEXEC sp_changeobjectowner @tblown, "chn"print @tblnamefetch next from tbl_cur into @tblnameendclose tbl_curdeallocate tbl_cur

方案二：

1、手动修改系统表；
2、设备可以手动修改表；

exec sp_configure "allow updates",1RECONFIGURE WITH OVERRIDE

3、更改对象所有者。

update sysobjects set uid = 1 where uid = 5update sysobjects set uid = 5 where uid = 1 AND xtype != "S"update sysobjects set uid = 1 where name = "syssegments"update sysobjects set uid = 1 where name = "sysconstraints"exec sp_configure "allow updates",0RECONFIGURE WITH OVERRIDE
