如何从另一个表插入并使用PK插入SQL Server中的多个表？

Question

I'm looking to copy info into another table but as each record is created I will be using a unique identity to generated a new PK. I also want to use that PK to insert into another table eg

INSERT INTO Table1(a, b) SELECT a, b FROM TempTable

INSERT INTO Table2(id, description) VALUES([PK From new record created in Table1], 'Test')

Is this possible?

Answer 1

You should realize that your code can create more than one new record.

The following captures all the new ids into @ids and then inserts all of them into the new table:

declare @ids table (int id);

insert into table1(a, b) 
    output inserted.id into @ids
    select a, b 
    from TempTable;

insert into Table2(id, description) 
    select id, 'Test'
    from @ids;
