Order and OrderDetails

If i am going to save a record of OrderDetails, I need the OrderId(foreign key) from the Order table. The question is when saving a record of Order, the OrderId is automatically generated

So how do I refer to that particular OrderId, when inserting a record in OrderDetails? This has confused me so much.

I am using Microsoft SQL Server 2005

Order Table

OrderId
CustomerId
Date
Total

OrderDetails

OrderDetailId
OrderId
ProductId
Quantity
UnitPrice

The answer will depend on what datatype your OrderID is. Assuming it's an int identity, you can call SCOPE_IDENTITY() to return the identity of the last added row.

For example

INSERT INTO dbo.Orders (CustomerId, Date, Total)
VALUES (@CustomerId, @Date, @Total);

DECLARE @OrderID int
SET @OrderID = SCOPE_IDENTITY()
