Re: Need some assistance with an SQL query

Thinking about this, I realized I may have misunderstood what you're trying to do. Do you want to update all the records in the a file that have matching mxplan, mxdiv, mxins, mxben, and mxppo records in the b file? Or do you only want to update those
records in the a file that also have mxtfrm='V' and mxtdt=0? The statement I posted earlier should to the latter; for the former, you might try:

Exec Sql
Update plnmaxl1 as a
Set a.mxUdt = :xDate,
a.mxUtm = :xTime,
a.mxUop = 'SPR33684',
a.mxCpdy = 'Y',
a.mxUty = 'C'
Where exists
(select * from xplnMax as b
where a.mxplan = b.mxplan and
a.mxdiv = b.mxdiv and
a.mxins = b.mxins and
a.mxben = b.mxben and
a.mxppo = b.mxppo)
and exists
(select * from plnMax as c
where a.mxplan = c.mxplan and
a.mxdiv = c.mxdiv and
a.mxins = c.mxins and
a.mxben = c.mxben and
a.mxppo = c.mxppo and
c.mxtfrm = 'V' and
c.mxtdt = 0);

Seems a little cumbersome, but that might be what you need to do ....

I'm not sure I can explain it, but I think you want to take the tests for a.mxtfrm and a.mxtdt out of your EXISTS clause, since they don't care about anything in xRouteMax:

Exec Sql
Update plnmaxl1 as a
Set a.mxUdt = :xDate,
a.mxUtm = :xTime,
a.mxUop = 'SPR33684',
a.mxCpdy = 'Y',
a.mxUty = 'C'
Where a.mxtfrm = 'V'
and a.mxtdt = 0
and exists
(select * from xplnMax as b
where a.mxplan = b.mxplan and
a.mxdiv = b.mxdiv and
a.mxins = b.mxins and
a.mxben = b.mxben and
a.mxppo = b.mxppo);
