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)

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。
是的,可在。 采用“遗产”条款:
设置:
create table Page (id int )
create table Content (id int , pageid int, title varchar(100), content varchar(max))
create table pages (id int, title varchar(100), content varchar(max))
insert into pages values (1, Lorem , Ipsum );
insert into pages values (2, eum , aliquam vivendo placerat ad );
实际插入:
insert into Content (id, pageid, title, content)
output inserted.pageid into Page(id)
select id, id, title, content from pages;
证明:
select * from Page;
select * from Content;
这实际上可能有用,因为这两个字在一份说明中,因此自动列入默示交易。
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。
