Re: Left joing is taking too much time

Maybe this is one of the troubles:

(date(dt.date) >= '2007-04-01' and date(dt.date) <= '2008-03-01')

because the optimizer cannot predict the results of the function it uses table scan.

Thus, maybe the solution will be to store date and time separately and create index on dates.
