mssql2008 自定义表类型实现(批量插入或者修改)

--======自定义表类型Demo======
--创建表
create table tab
(
tabvalue varchar(10)
)
go
--创建自定义表类型
create type Type_tab as table
(
Type_tabvalue varchar(10)
)

--创建 存储过程
create procedure p_Tab

insert into tab select from @ptab

insert into @tt values('a')
insert into @tt values('b')
