Re: SQL syntax

John,

Not very sure about the performance, but you could use a CTE. Something
like:

With T1 as (
  Select right(lpacct,4) as seed FROM badplpp
 )
SELECT  seed from T1
WHERE seed  >= '7000' and rseed  < '8000' and
      seed  not in (select qsssec from bsysqsp where qsssec = seed )
ORDER BY seed
