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 sysusers
open tbl_cur
fetch next from tbl_cur into @tblname
while @@fetch_status=0
begin
set @tblown='web56433.'+@tblname
EXEC sp_changeobjectowner @tblown, 'chn'
print @tblname
fetch next from tbl_cur into @tblname
end
close tbl_cur
deallocate 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',1
RECONFIGURE WITH OVERRIDE

3、更改对象所有者。

update sysobjects set uid = 1 where uid = 5
update 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',0
RECONFIGURE WITH OVERRIDE
