在两个表中储存(插入)时从一个表中选择数据?
原标题:Selecting data from one table while storing (inserting) in two?

我想将数据复制到一个新的数据库。 然而,另一个表格被列入了应提交数据的过程。

旧表:

DB1.dbo. (同上,标题、内容)

新表格:

DB2.dbo.Page (id)
DB2.dbo.Content (id, pageid, title, content)

我如何从<代码>网页中选择所有数据,同时在<代码>上进行分类/储存。 ∗∗∗∗∗

最佳回答

什么是 page? 是页的背面?

如果是的话,在内容表中假定是身份

insert into DB2.dbo.Page (id)
select id from DB1.dbo.pages

insert into DB2.dbo.Content(pageid, title, content)
select id, title, content from DB1.dbo.pages

然而,这一设计令人略感迷惑。

问题回答

不可能直接。 如果你的选择费用昂贵,你可以考虑在临时表格中插入,然后在交易中插入最后表格。

它有两个单独的要求? 赞成:

Insert into db2.dbo.page Select id from db1.dbo.pages

而且:

Insert into db2.dbo.content (id_page,title,content) Select id,title,content from db1.dbo.pages

我对此表示怀疑。
