I've several fields for linked tables. I've created indexes for such fields
to accelerate results.
Modcode is an index. not makecode.

I've 50 tables with about 10 connected tables at every query. This is the
only one that fails. Other query are bigger and more time consuming and they
don't fail.

Don't know the web server, but they are quite good on hosting, they are
recommended for bigger sites than our.

My XP takes more time to execute queries than on the server. So the problem
seems not the machine.
Regars Stefan and thanks for your help.
I finally fixed it, probably database structure (I'm not a professional
database guy, I'm a php programmer).
Cheers.
