I have made this post before but did not get any response. Can
someone at least tell me if this is normal. All help will be
appreciated.

I have a database (FB 1.5) with about 300 000 records in one
table, I am using IBO for connectivity. The problem is that when I do
a query (on the big table) whether there is data returned or not +/-
250 megs of ram gets used. The ram is only freed once I disconnect
from the database.

What can I do to make the memory usage less?

Thanks
William
