You're searching on a calculation so I'm pretty sure that MySQL is not
using an index for the search. You should use explain in front of your
query to see if MySQL is using indexes. You do have that date field

You should search on ApacheDate between 9/1/2003 and 10/1/2003.

and all the amounts (A1, A2, ..., A6) - 6 rows. A client can be

Thanks but I have the tables. What I didn't know is how I can join them.
ok, but you got it now? The final step in my previous message was what you

Your solution work only with a table of clients, I don't have one. I
have only 6 tables with clients and amounts and I need to join them.
Should I have to make a table with clients? It's realy necessary?
Please reply to the list, others may have similar problems. :)

Are you sure you don't have any errors in your SQL? Maybe your query
returns a karthesian product - and this might kill your J2EE
application.
Check out your slow-log - the query is probably there.

you can create a temporary table (as del_temp_table) by this select command:
SELECT faqcat.cat FROM faqcat LEFT JOIN article ON faqcat.cat = article.cat
WHERE article.cat IS NULL;
then delete them:
DELETE FROM faqcat USING faqcat, del_temp_table WHERE faqcat.cat =
del_temp_table.cat ;

Darryl,
At first blush, I would try something like:
DELETE faqcat
FROM faqcat LEFT JOIN article
ON faqcat.cat = article.cat
WHERE article.cat Is Null;
I vaguley remember MySQL implementing syntax permitting users to remove data
from one or more tables. I think this might be your ticket.

Hi Daniel,
Yes, query_cache_type is 1 by default if you don't set it. :-) It's not
used by default, however, because query_cache_size is 0. You need to set
query_cache_size to 16M, 32M, etc.
Hope that helps.
