RE: SQL -not returning records with null values

Since most of the code is missing here I'm going to assume that you have a
Where clause.

If the field is allowed to contain Nulls then you have to test for it. I
know this seems counter intuitive to people new to SQL but null is not
anything and will return true when compared to a value.

Add something like this to your Where clause - and ifnull(TestField,' ')
<> ' '

That should fix it.

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?
