问题描述：
       我恢复别人备份在别的机器上的SQL数据库到我的机器上的SQL SERVER，恢复后该数据库中有一个mis用户，该用户是所有者，很多表的所有者也是他，但我的安全性里的登录中没有该用户，我删除不了该用户，提示“因为选定的用户拥有对象，所以无法除去该用户”！
问题解决方式：
      1 如果是一张表有此问题，解决方式如下：
       
       exec sp_changeobjectowner mis.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_cursor
            GO

EXEC ChangeAll @old = 'mis', @new = 'dbo'

这样就完成了批量修改权限的工作
