Re: Delete with an inner join

Look into the WHERE EXISTS clause. You cannot do a join on a delete
statement. So instead you put the joined files into a where exists clause.

ie.

delete from filea a
where exists(select '1' from fileb b join filec c on b.key = c.key where
a.key = b.key)
and ... -- other where conditions

Hi,

Can anyone help me with this SQL statement? I have written a select
statement that works, but I need to convert it to a DELETE statement but
can't get it to work correctly. I looked in the archive and in some
manuals but can't find an exact sample to figure out what I am doing
wrong.

SELECT a.pzcono, a.pzcsno, a.pzwhid, a.pzrqsd, a.pzcspo, a.pzitno,
a.pzqtor, b.obqtor, a.pzqtsh, b.obqtsh, a.pzlfcd, b.oborno, b.oborgn

FROM zpofilld A
inner join hsdet B ON
A.pzcono = B.obcono
AND A.pzcsno = B.obcsno
AND A.pzitno = B.obitno
AND a.pzwhid = B.obwhid
inner join hshed d ON
A.pzcono = d.oacono
AND A.pzcsno = d.oacsno
AND A.pzrqsd = d.oarqsd
and a.pzcspo = d.oacspo
and d.oaorno = B.oborno
WHERE d.oaortp = 'I' and a.pzqtor = 0
ORDER BY 2,1

Any help would be appreciated. Thanks.
