HI Art
What I had on my previous email won't do that
You will need something like this
With maxqty as
(Select max (qty) as highqty from file)
Select a.style, a.class, a.qty from file a join maxqty b on a.qty = b.highqty

You might get more than one record though

I need one record (style, class) with the greatest qty for style and
class. I don't need to return the qty.

I'm not able to get the syntax for your example right.

HI Art
Just realized
Are you asking for the one record with the highest qty or the styles and
classes with the highest qty for each style and class (which is what I just
gave you)

HI Art

Not near a machine at the moment, but what you are asking for is to
compare the same file against itself where a.style = b.style and a.class =
b.class and a.qty gt or = max (b.qty)
I had to use gt
Cannot find the greater than sign

Hope this makes sense

Subject: [EXTERNAL] Sql select max value question

I have a table with 3 columns, style, class, quantity

There are many classes for each style. I want my select to return only the
class with the highest quantity.

I've been playing with max(qty) and fetch first row only from examples I
found on the web but can't get exactly what I want.

Thanks
