Look at the following two queries.
select casepid, origpid
from virbcase
where date_trunc('day', origdt) >= '2003-07-01'
and date_trunc('day', origdt) <= '2003-07-31'
and origpid in (select pid from party where partyid in ('00339',
'00310',
'00320'))
and not exists (select pid from casecombo where casepid = secondpid)
select casepid, origpid
from virbcase
where date_trunc('day', origdt) >= '2003-07-01'
and date_trunc('day', origdt) <= '2003-07-31'
and origpid in (select pid from party where partyid in ('00339',
'00310',
'00320'))
and casepid not in (select secondpid from casecombo)
The second query is broken and I don't understand why.
Correlating the subquery as is done in the first query fixes it.
