Hi Fred, Yes I am pretty sure, because I write it out using to_sql before I run. At the moment is seems like a Windows memory problem rather than a ruby problem. As I commented on the StackOverflow thread I now have a solution for my immediate problem. Since I am calculating averages over a date range over three years - and since the dates are actually end-of-month dates - I am really calculating an overage over 36 distinct months. I therefore do my query in two steps. First, I calculate averages and counts per month. Second I aggregate up to get averages over 36 months. Runs pretty quick.
But I haven't solved the problem and I haven't been able to find comments from anyone else experiencing the same thing. So the mystery remains. Ruby-prof, though. Thanks for that. You made me install it and its actually rather nice. William -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
