存储过程中执行多个语句的问题
我的表结构如下:
create table dt_articleclass
(
acid tinyint primary key identity(1,1),
acname varchar(50) not null
)
create table dt_article
(
aid int primary key identity(1,1),
atitle varchar(50) not null,
acontent text not null,
aauthor varchar(30) not null,
acid tinyint not null foreign key references dt_articleclass(acid)
)
create table dt_articlepulish
(
apid int primary key identity(1,1),
aptime datetime not null,
apaccount int default 0,
uid int not null foreign key references dt_user(uid),
aid int not null foreign key references dt_article(aid)
)
要编写存储article的存储过程,因为涉及到三个表,不知该怎样编写存储过程,我编写的如下,但是不可以
create proc addarticle
@acid int,
@title varchar(50),
@content text,
@author varchar(50),
@addtime datetime,
@userid int
as
declare @aid int
insert into dt_article(atitle,acontent,aauthor,acid) values(@title,@content,@author,@acid)
select @aid=max(aid) from dt_article
insert into dt_articlepublish(aptime,uid,aid) values(@addtime,@userid,@aid)
go
请问那里出了问题
------解决方案--------------------要先dt_articleclass中有对应的acid,才能向dt_article插入,再向dt_articlepublish中插入
