步骤一 ：在问题库中建立存储过程
IF OBJECT_ID('ChangeAllObjOwner') IS NOT NULL DROP PROC ChangeAllObjOwner
GO
CREATE PROCEDURE ChangeAllObjOwner (
@oldowner sysname,
@newowner sysname
)
AS
DECLARE @objname sysname
SET NOCOUNT ON
--check that the @oldowner exists in the database
IF USER_ID(@oldowner) IS NULL
BEGIN
RAISERROR ('The @oldowner passed does not exist in the database', 16, 1)
RETURN
END
--check that the @newowner exists in the database
IF USER_ID(@newowner) IS NULL
BEGIN
RAISERROR ('The @newowner passed does not exist in the database', 16, 1)
RETURN
END
DECLARE owner_cursor CURSOR FOR
SELECT name FROM sysobjects WHERE uid = USER_ID(@oldowner)
OPEN owner_cursor
FETCH NEXT FROM owner_cursor INTO @objname
WHILE (@@fetch_status <> -1)
BEGIN
SET @objname = @oldowner + '.' + @objname
EXEC sp_changeobjectowner @objname, @newowner
FETCH NEXT FROM owner_cursor INTO @objname
END
CLOSE owner_cursor
DEALLOCATE owner_cursor
GO
步骤二：
在查询分析器里执行下列语句：
EXEC ChangeAllObjOwner @oldowner = '原先的用户名', @newowner = '新的用户名'
