Re: Date/Time fields in DB file

However, how does that DFT really work? Just because one thing works with
UPDDTA doesn't necessarily mean it will work that way in an RPG program.
Often the buffer gets initialized totally different. For example, DDS has
keywords to restrict a value of a field to certain characters, for example
Y or N. And that may even be enforced in UPDDTA. However if I want to
write an RPG program, or even use a sql insert statement, I can put
whatever I want into that field. You define that with DDL, with a
constraint right there within the DDL and it can't be set to any other
value. Sure you can bolt constraints onto a DDS defined file with ADDPFCST
but that's not within the DDS and the next person comes along and
recompiles the DDS and your constraints are gone.

If TrustedLink will let Greg do that, of course. I think I covered that in
a reply - there is a DFT in DDS, and the docs suggest it will use current
date or time, if you don't specify it - I think you also should not specify
a field in the WRITE.


SQL is the ticket here, of course, as you say.

Here's the problem: "... an existing database file (DDS)".
Quit that. Use SQL's DDL instead. DDL will allow you to default new
columns to current date, etc. DDS will NOT. Sure, you can add triggers
and stuff but that isn't really DDS, is it?

I recently added an ISO date and ISO time field to an existing database

the record was created. Tli support says the EDI translator won't update
those "automatically".

Anyone know of a method of getting these fields to update with current
info upon creation? Otherwise, I'll have to update them in my RPG
processing program.
