sql question

["Rowe, Sheri" <srowe@xxxxxxxxx>]

Hi all,

I have an SQL Question.  I can do this in 2 passes but think it should
be able to be done with 1.

I have 2 files, PODET - PO detail and PORDT - PO receipts file.  I want
to join the files to get a list of:

1.  All PO's from PODET that have a status of 'O' (regardless if it is
in PORDT)
2   All PO receipts records which match the PODET file with a status of
<> 'C'
3.  If there is a matching record between PODET and PORDT and the PODET
status = 'O' but the PORDT records = 'C' I still want the PODET record
to appear but not the PORDT record.
4.  There may be multiple records in PORDT that correspond with PODET
(Co#, PO#, PO line #, Item #)

I have tried multiple iterations but I can't get the all the PODET
records with a status of 'O' and only the PORDT records that do not have
a status = 'C', without performing 2 passes.

Any help would be greatly appreciated.

Thanks.
