Basic Query Question

Here's a simple query question. I have tables. One is an order table and
one is an order detail table.

tOrder
tOrderDetail

The tOrder table contains basic info like customer name, date, a flat rate,
etc. The tOrderDetail table is linked to tOrder by a field called DetailID.
Some orders in the tOrderDetail table actually have related data in the
tOrderDetail table. I'm trying to write a simple query that will capture
all of the data from both tables - can't seem to do it. It seems as though
I can either capture records with data in tOrderDetail or records with out -
not both. Any thoughts would be greatly appreciated.

Thanks!

re: Basic Query Question

What you need is probably a LEFT JOIN:

Select <field lists> FROM tOrder LEFT JOIN tOrderDetail ON
tOrder.DetailID=tOrderDetail.DetailID

re: Basic Query Question

Thanks Herbert. I was able to get it going with the wizard. However, I'm
getting multiple detail line items. For example, on order might have 4 or 5
detail lines in th detail table. I'd like to subtotal those amounts as a
single line item. I'm going to battle the wizard for this. Any thoughts?

re: Basic Query Question

Select <field1>, <field2>, sum(<field3>)
FROM tOrder LEFT JOIN tOrderDetail ON tOrder.DetailID=tOrderDetail.DetailID
GROUP BY tOrder.DetailID

Or learn something about GROUP BY either from the help or from the web.

Or actually you'd better pick up a book about SQL. I once, which was
actually just last September, picked up a "Learn SQL in 10 minutes"
published by Sams and thereafter could feel rather comfortable with SQL.
Before reading this book, I knew totally nothing about SQL. After reading
it, I found out that SQL was actually rather simple, although it certainly
took a long time to master. But at the same time, you don't need to master
it before you can get any good use out of it:)
