数据库操作当中，当数据库对象列表不只有一个普通的元素——objectname时，你将要使用objectowner.objectname来引用对象，但如果需要更改当前数据库中对象的所有者可以使用系统存储过程 sp_changeobjectowner （点击这里更详细）
sp_changeobjectowner
更改当前数据库中对象的所有者。
语法： sp_changeobjectowner [ @objname = ] 'object' , [, @newowner = ] 'owner'. 参数. [@objname =] 'object'.
但往往由于数据库对象过多，希望批处理更改当前数据库中对象的所有者，那么你可以尝试使用Net Fetch的 nf_ChangeObjectOwner 存储过程来完成批处理。具体用法如下：
首先使用以下代码创建存储过程——
nf_ChangeObjectOwner
将Sql Server对象的当前拥有者更改成目标拥有者
语法：nf_ChangeObjectOwner [, @current_Owner = ] 'owner',[,@target_Owner =] 'owner',[ ,@modify_Type=] type
复制代码 代码如下:
if exists (select * from sysobjects where id = object_id(N'[nf_ChangeObjectOwner]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure nf_ChangeObjectOwner
GO
Create PROCEDURE nf_ChangeObjectOwner
@current_Owner nvarchar(255),
@target_Owner nvarchar(255),
@modify_Type int
AS
DECLARE @str_Tbl_Name nvarchar(255),@object_Num int,@current_Owner_uid smallint
Set @object_Num = 0
DECLARE @return_status int
Set @return_status = -1
Set @current_Owner_uid = (Select uid From sysusers Where [Name] = @current_Owner)
If Not (Len(@current_Owner_uid)>0)
RETURN -1
If (@modify_Type = 1)
DECLARE ChangeObjectOwner_Cursor CURSOR FOR Select [Name] From sysobjects Where (type='U' or type='V' or type='P') and userstat=0 and [Name]<>'nf_ChangeObjectOwner' and status>-1 and uid = @current_Owner_uid
Else
DECLARE ChangeObjectOwner_Cursor CURSOR FOR Select [Name] From sysobjects Where (type='U' or type='V' or type='P') and userstat<>0 and [Name]<>'dtproperties' and uid = @current_Owner_uid
OPEN ChangeObjectOwner_Cursor
BEGIN TRANSACTION Change_ObjectOwner
FETCH NEXT FROM ChangeObjectOwner_Cursor INTO @str_Tbl_Name
WHILE (@@FETCH_STATUS = 0)
BEGIN
Set @str_Tbl_Name = @current_Owner + '.' + @str_Tbl_Name
Print @str_Tbl_Name
EXEC @return_status = sp_changeobjectowner @str_Tbl_Name, @target_Owner
IF (@return_status <> 0)
BEGIN
ROLLBACK TRANSACTION Change_ObjectOwner
RETURN -2
END
Set @object_Num = @object_Num + 1
FETCH NEXT FROM ChangeObjectOwner_Cursor INTO @str_Tbl_Name
END
Print @object_Num
COMMIT TRANSACTION Change_ObjectOwner
CLOSE ChangeObjectOwner_Cursor
DEALLOCATE ChangeObjectOwner_Cursor
Go
Usage（使用方法）: Exec nf_ChangeObjectOwner 'dbo','你的用户名',0
——将所有用户表的拥有者更改成'你的用户名'
Usage（使用方法）: Exec nf_ChangeObjectOwner 'dbo','你的用户名',1
——将除了用户表之外数据库对象（视图、存储过程）的拥有者更改成'你的用户名'
