I got a feeling this isn't possible, but I thought I'd ask just in case. I want to do something like this:

SELECT trips
DELETE ALL FOR trips.client_num NOT IN (SELECT client_num FROM clients)

Basically, there's a lot of orphaned trips in the table and I want to clear them out. Is there any way to do that short of scanning through the trips table and looking up each client_num?

Thanks,
