Hi,

I am creating an order detail dataset for a particual order using a typed
dataset.


I created a stored procedure:

CREATE PROCEDURE SPOrderDetail
(
@OrderID int
)
AS
SELECT OD.ProductID, OD.UnitPrice,OD.Quantity, P.ProductName
FROM OrderDetails OD INNER JOIN Products P
ON OD.ProductID = P.ProductID
WHERE OD.OrderID =@OrderID


Now my question is if I can use this stored procedure to fill a typed
dataset that has tow distinct table (OrderDetails and Products) and defines
a relationship or do I have to create a typed dataset that holds all fields
from the SP on a single table?

Thanks,

Jeronimo Bertran
 
Hi Jeronimo,

First of all, I would like to confirm my understanding of your issue. From
your description, I understand that you need to know if you can use the
joined table to fill multiple tables in a typed DataSet. If there is any
misunderstanding, please feel free to let me know.

As far as I know, we cannot use this stored procedure to fill the
DataTables, since no table in the DataSet contains both columns from Order
and Products table. In this case, I strongly recommend you create 2 stored
procedures, which fill 2 tables in the DataSet seperately. Then we can
create a relation object between 2 tables. If you need to see the Product
information in the OrderDetails table, you can add an expression column in
the OrderDetails table to achieve this.
