The advice from Dr. Richard Hipp did the trick. I added a multi column index
and now the query takes less than a tenth of a seconds. Thanks a lot for the
help you guys!
I was going to send this acknowledgement by replying to the message by Dr.
Hipp, but for some reason I didn't receive it, so

in DevCpp (Windows 2000). My problem is while Sqlite compiles with the c
compiler, it does not with c++ compiler. The main problems are:
1) comparision
