mssql批量修改权限_数据库技巧

    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
