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
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

调用方法: exec nf_changeobjectowner @current_owner,@target_owner,@modify_type
输入参数: @current_owner nvarchar(255) --对象的当前拥有者
@target_owner nvarchar(255) --对象的目标拥有者
@modify_type int --0为默认,更改表的拥有者;1为视图和存储过程
输出参数: return值 = -1 --操作对象为0,操作对象不存在
= -2 --操作失败,可能对象被锁定
= 0(默认值) --操作成功,打印更改对象数目@object_num
@object_num --sql 打印值,返回更改成功的对象数目
