Re: Testing for a record before update or insert without using a function.

Why not try doing the update and if that fails i.e. returns a value of 0
(no row updated), then do the insert. Thus if your high runner case is
that the entry exists, then you are going to bypass having to test if
the entry exists.

Is it possible to test if a record exists in a table and then if it does
do an update on that table or if it doesn't do an insert ? I've looked
around the documents and it seems everything points towards a function?

Is this the only way or has someone done this before.....

TIA
