Re: Can I do this with SQL (in a STRSQL session)?

Some example data showing what you have and what you want would help...

But as I understand your question...

"count the unique combinations of account-ID, invoice number, invoice date,
and part number,"


select count(distinct account-ID concat invoice_number concat invoice_date
concat part_number)
from mytable

" each unique combination has the sum of the quantity shipped values

for all records matching that combination, and pour that result set into

a file."

create table myoutput as
(select account-ID, invoice_number, invoice_date, part_number,
sum(qty_ship) as tot_ship
from mytable
group by account-ID, invoice_number, invoice_date, part_number
)
with data;

I have a file. It contains an account-ID, an invoice number, an invoice

And it has multiple examples in which a given combination of account-ID,
invoice number, invoice date, and part number yield multiple records
(don't ask; I'm not the one populating it).

I'd like to (1) count the unique combinations of account-ID, invoice
number, invoice date, and part number, and (2) produce a result set in
which each unique combination has the sum of the quantity shipped values
for all records matching that combination, and pour that result set into
a file.

Given my limited knowledge of SQL, and that most online SQL resources
assume either MySQL or some M$-proprietary database, rather than
DB2/400, I'm not sure how I would do that.
