RE: SQL loval date/timestamp

Joel,

If you have a date-type that displays four digit years (*ISO, as in your
example), then the valid range of years is extended.  Only two digit year
formats suffer the limitations you describe.

Check the field you are fetching into, and I'll bet it's *MDY, or one of the
other limited formats.

Hi guys, 

Sorry I haven't gotten back to this yet, I've been out of town since
Tuesday.

I have some traditional, DDS based, PFs with Date fields that may or may
not get populated at the initial write.  If they do not get populated,
then their default value is '0001-01-01' as one might expect.  However,
what I've run into is that in an SQLRPGLE program, when I try to fetch a
record that has one of these fields in it, I get an SQL error saying "A
Date or Timestamp is Invalid" and the record is NOT fetched into the
DS.  If I put a date value in the record then it processes as desired.

I remember hearing this from other people, and I remember reading that
the lowest Date SQLRPGLE will process is like '1940-01-01' or something
like that, but I can't seem to find the reference again.  That way, when
I write a record I can insert a date that SQL will process, and if I
know what it is I can programmatically ignore it.

Thanks,

Joel
