主题：[求助]SqlServer 实现oracle 中触发器 before delete

1）学会使用搜索，如：http://www.baidu.com/s?wd=sqlserver+%B4%A5%B7%A2%C6%F7+before&rsv_bp=0&rsv_spt=3&inputT=16000

2）通过改写delete操作，可以实现近似的效果

create table a(aa int primary key);
create table b(bb int references a(aa));
insert into a values(1);
insert into b values(1);
go

create trigger tri_delete_a on a
instead of delete
as
begin
 declare @abc int;
 select @abc = aa from deleted;
 delete b where bb = @abc;
 delete a where aa = @abc;
end

此时可以发现可以在删除a记录前更改其他表
