带有外键/主键的SQL表2表插入

Question

i have 2 tables. One is Order header the other one is order lines. Order header:

OrderID Customer IntegrationID(Identity auto Incremental)

Order lines :

OrderID Itemid IntegrationID

The thing i want to do: i run a stored procedure which populates these 2 tables with data and i want the order line to have the same IntegrationID as the order header. For example when i insert to order header:

OrderID Customer IntegrationID(Identity auto Incremental)
500       5          1
501       4          2

And in the order lines i want to have the data like this:

OrderID Itemid IntegrationID
 500     101         1
 500     102         1
 501     102         2

Any ideas how can i achieve that? Orderheader and orderlines are linked via ORDERID field.

Answer 1

Its Simple,
For Example In Your Stored Procedure you insert record in table "Order Header"

Insert into (col1,col2) values ("val1","val2")

then you should use the following query to insert into table "Order Line"

SELECT @new_identity = SCOPE_IDENTITY()

Then insert this @new_identity in the query

Insert into Order Line (OrderID Itemid IntegrationID) values 
("value1","value2",@new_identity)

but make sure these both query executes in same stored procdure if you have individual SP for both then you should have return from the first SP
