[Zope-dev] Z SQL Caching

Hi all, I have a Z SQL method that is currently returning around 25000 rows. Is there a way to see if it is pulling that data from the cache or is doing a refresh? Alternatively, and maybe this will answer the first question, the Z SQL method is run essentially twice, each time with different parameters. Does it cache each instance, or does it cache the first, then when it's run again with different parameters, kill the cache and re-run everything? Thanks, Dale Hirt
