Question

I have written a query for sales by customers in groups it is as follows:

SELECT customerid,
SUM (salestax1)As total_salestax1,
SUM(total_payment_received) As total_payment_recieved,
COUNT (orderid)as order_qty,
SUM(paymentamount)As paymentamount
 FROM Orders_74V94W6D22$
WHERE orderdate between '7/6/2011 16:35' and '2/3/2012 11:53'    
GROUP BY customerid 

but this query shows only 5 fields but I need to show following fields:

orderid    billingcompanyname    billingfirstname    billinglastname    
billingcountry    shipcountry    paymentamount creditcardtransactionid    
orderdate    creditcardauthorizationdate    orderstatus    
total_payment_received    tax1_title salestax1

then how to deal with it?

Answer 1

you need to understand what GROUP BY means.
If you are grouping by customerId, you will have only one customer because all data is grouped into it.

How do you want to group by orderid and display the orderid on your result set? If you have 10 order ids, do you expect 10 rows on the result? If yes, fine, group by it but I don’t think that’s what you want

EDIT:

Well, this is NOT a good idea, your table structure is WRONG and I dont think you fully understand that a group by means, BUT I think this query will get your result:

 SELECT customerid, 
 (select top 1  [column1] from Orders_74V94W6D22$ where customerid = ORD.customerid),
 (select top 1  [column2] from Orders_74V94W6D22$ where customerid = ORD.customerid),
 (select top 1  [column3] from Orders_74V94W6D22$ where customerid = ORD.customerid),
 SUM (salestax1)As total_salestax1, 
 SUM(total_payment_received) As total_payment_recieved, 
 COUNT (orderid)as order_qty, 
 SUM(paymentamount)As paymentamount
 FROM Orders_74V94W6D22$  ORD
 WHERE orderdate between '7/6/2011 16:35' and '2/3/2012 11:53' 
 GROUP BY customerid
