Question

I have a table with a collection of orders. The fields are:

• customerName (text)
• DateOfOrder (datetime).

I would like to show totals of orders per week per customer. I would like to have it arranged for the Friday of each week so that it looks like this:

all dates follow mm/dd/yyyy

"bobs pizza", 3/5/2010, 10
"the phone co",3/5/2010,5
"bobs pizza", 3/12/2010, 3
"the phone co",3/12/2010,11

Could somebody please show me how to do this?

Thanks

Answer 1

Make a field which you can group by more easily.

SELECT COUNT(OrderID), WeekStart
FROM 
(
 SELECT *, 
  dateadd(week, datediff(day,'20000107',yourDate) / 7, '20000107') AS WeekStart  
 FROM Orders
) o
GROUP BY WeekStart;

20000107 is a known Friday.
