Subject RE: [ib-support] UPDATE when row does not exist
Author Christian G├╝tter
Art,

glad to see you're still there :-)
It was a great time with you and you were a
busy writer - the lists won't be the same without
you (at least for me).

Concerning my question: you're right. I guess it is
more a philosophical topic: when I try to select a
record and there isn't any, I would expect no error.

But when trying to update a record using the PK in the
WHERE clause, I would expect the record exists and
anticipate an error when it is not there.

As you said, Interbase's philosophy is different of mine -
so there is no more need to discuss :-(


Have a good time and try to stay tuned!


Christian
