Don't check for SQLCODE = 0 because there are situations where a warning
positive SQLCODE is returned.
With a warning the record is nevertheless returned. If you only consider
SQLCODE = 0 you may lose several rows.

Always check for
SQLCODE < *Zeros --> Error
SQLCODE = 100 --> Last Record

yes, sorry...
I should have said we first do a coalesce null to blank or zero, then tested
if sqlcod = 0...

That doesn't make sense as 0 <> 100 is true. Changing the if to
sqlcod =
0 should give fewer records not more if anything.

Subject: SQL -not returning records with null values

we have been coding our loops as follows:

dow sqlcod <> 100

....fetch records
if sqlcod<> 100
... write subfile, or write report line



evidently, the records with nulls return the 100?

we knew we should have had more records on the display, but when we
changed the if to "sqlcod = 0"
we received the records with null fields.

is this the proper fix, or is something else going on?
