Hi all,

I'm pretty new to SQL and I would need some help with following issue:

I have two tables:

SalesOrderHeader
SalesOrderLines

In the SalesOrderLines I have Quantity and Price

I would like to create a query that gets the SalesOrderId and calculates the total (qnt*price). SalesOrderId is the key.

SELECT
a.SalesOrderId, a.Customer, (TOTAL HERE SOMEHOW :)
FROM
SalesOrderHeader a, SalesOrderLines b
WHERE
a.SalesOrderId = b.SalesOrderId and
a.SalesOrderDate>=20130101




Thanks for the help : )

Try this ..

SELECT
a.SalesOrderId, a.Customer, sum(b.Quantity *b.Price)
FROM
SalesOrderHeader a, SalesOrderLines b
WHERE
a.SalesOrderId = b.SalesOrderId and
a.SalesOrderDate>=20130101
group by a.SalesOrderId, a.Customer

If SalesOrderDate is of Datetime datatype, you need to use date values within single quotes

a.SalesOrderDate>='20130101'

The next question would be, "Do you understand how it works?"

--Jeff Moden
RBAR is pronounced "ree-bar" and is a "Modenism" for "Row By Agonizing Row".

First step towards the paradigm shift of writing Set Based code:
"Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column."

When writing schedules, keep the following in mind:
"If you want it real bad, that's the way you'll likely get it."
