今天恢复一个在别人机器备份的数据库到SQL SERVER,恢复后该数据库中有一个mooip用户,该用户是数据库所有者,很多表的所有者也是他,但安全性里的登录中没有该用户,删除不了该用户,提示“因为选定的用户拥有对象,所以无法除去该用户”!
具体解决方式如下:
1 如果是一张表有此问题,解决方式如下:
exec sp_changeobjectowner 'mooip.tablename', 'dbo'
这样就把tablename指定的表的所有者赋值给了dbo用户
2 如果所有表都存在此问题,这是就要编写存储过程实现批量修改了
IF OBJECT_ID('ChangeAll') IS NOT NULL Drop PROC ChangeAll
GO
Create PROCEDURE ChangeAll (
@old sysname,
@new sysname
)
AS
DECLARE @objname sysname
SET NOCOUNT ON
IF USER_ID(@old) IS NULL
BEGIN
RAISERROR ('The @old passed does not exist in the database', 16, 1)
RETURN
END
IF USER_ID(@new) IS NULL
BEGIN
RAISERROR ('The @new passed does not exist in the database', 16, 1)
RETURN
END
DECLARE owner_cursor CURSOR FOR
Select name FROM sysobjects Where uid = USER_ID(@old)
OPEN owner_cursor
FETCH NEXT FROM owner_cursor INTO @objname
WHILE (@@fetch_status <> -1)
BEGIN
SET @objname = @old + '.' + @objname
EXEC sp_changeobjectowner @objname, @new
FETCH NEXT FROM owner_cursor INTO @objname
END
CLOSE owner_cursor
DEALLOCATE owner_cursorz
GO
EXEC ChangeAll @old = 'mooip', @new = 'dbo'
这样就完成了批量修改权限的工作
