Re: Embedded SQL For Screen Load

My advice...

Don't do it. SQL doesn't really support "Position To", instead it's

"Search/Subset By"

Really? What about the following?

where db_column >= :search

Lot's of posts over the years detailing the hoops needed in SQL to do a
position to (and provide the exact functionality you have now). Not

really

worth the effort IMO.

I don't see any hoops in doing the example above. The only challenge is if
there's nothing that matches and you want to display the previous record
as well as those that are greater than the search criteria. But I don't
see it much more difficult than trying to do the same after a SETLL.
