面的操作存在风险 建议做好数据库备份

1.单个修改 exec sp_changeobjectowner '[所有者].[对象名]', 'dbo' 例子： exec sp_changeobjectowner '[test].[dnt_users]', 'dbo' 执行后 数据库中dnt_users表的所有者从test变为dbo

2.批量修改

2.1 现在查询分析其中执行 下面的sql语句 建立名为changename存储过程

CREATE PROCEDURE dbo.changename
@OldOwner as NVARCHAR(128),--参数原所有者
@NewOwner as NVARCHAR(128)--参数新所有者
AS
DECLARE @Name as NVARCHAR(128)
DECLARE @Owner as NVARCHAR(128)
DECLARE @OwnerName as NVARCHAR(128)
DECLARE curObject CURSOR FOR
select 'Name' = name,
'Owner' = user_name(uid)
from sysobjects
where user_name(uid)=@OldOwner
order by name
OPEN curObject
FETCH NEXT FROM curObject INTO @Name, @Owner
WHILE(@@FETCH_STATUS=0)
BEGIN
if @Owner=@OldOwner
begin
set @OwnerName = @OldOwner + '.' + rtrim(@Name)
exec sp_changeobjectowner @OwnerName, @NewOwner
end
FETCH NEXT FROM curObject INTO @Name, @Owner
END
close curObject
deallocate curObject
GO

2.2 执行存储过程changename exec changename '原所有者名','新所有者名' 例如 exec changename 'test','dbo' 则当前数据库中所有对象所有者 从 test 变为 dbo
