Re: SQL: Join file 1 and 2, but only if not in 3

[Alan Shore <AlanShore@xxxxxxxx>]

Here is something similar that we use on our syste
select *        from intbadpfxx a where not exists
(select * from intbadpfxx b where b.atmrec = 'H' and
a.atmseq = b.atmseq and
exists
(select * from intbadpfxx c where c.atmrec = 'S' and
C.atmseq = b.atmseq
and exists
(select * from intbadpfxx d where d.atmrec = 'D' and
c.atmseq = d.atmseq)))
I know it doesnt directly answer your question, but it shows the idea of
what you want

Hi list!

This SQL beginner has a question:

SELECT
T02.ITNBR, T02.STID, T02.ITRV, T02.ITDSC,
T02.UNMSR, T02.QCTYP, T02.QCDAY, T02.INTYP, T02.BLCF, T02.ALLOC
FROM WHDTA/SHRITMS T01, AMFLIB1/ITMRVA T02
WHERE T01.ITNBR = T02.ITNBR AND (STID = 'H1P')
ORDER BY  T02.ITNBR ASC, T02.ITRV ASC

I am joining these 2 files and listing the results; however, I have a new
requirement and that is to list these fields ONLY if T02.ITNBR is not in
our history file called IMHIST.  What will be the SQL statement to provide
these results?

Thanks in advance!
