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

[Charles Wilt <charles.wilt@xxxxxxxxx>]

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;
