LOCATE Backwards?

Hello:

I have a situation in my app where I am having to pick up what will presumably be the last row in a table. Mind you, the general situation is that it might not be if in a multiuser situation.

With the current situation, I can use an index to find that row really fast.

BUT ...

What if an index is not appropriate? Is there any way to do a LOCATE backwards (or something equivalent)? (The table has 186,574 rows currently so searching backwards would definitely be worth it.) I do not think there is such a critter, but maybe, you know better?

Sincerely,

Gene Wirchenko
