RE: Sql question

["Walden H. Leverich" <WaldenL@xxxxxxxxxxxxxxx>]

Actually, I think 469 would be the only row returned, but try:

Select cust# from transfile
        where cust# in
                (select cust# from transfile where item# = '12a')
        and cust# NOT in
                (select cust# from transfile where item# = '13a')

-Walden

I have a file that has data like this

 <file:Transfile> file:Transfile
Cust#           Item#
123             '12a'
123             '13a'
469             '12a'
550             '13a'

I want to be able to select customers who have ordered item '12a' but not
'13a'

So I would end up with

123 as the only record returned out of this data set.

Can I do this with a SQL statement?

Thanks

Mike
