The question is, is there any way to modify this query so that it would
return the team having the most entries?
Theoretical what I would like:

| a |600 | team1

For the exchange rates only you don't really need more than one table. I
work with an enterprise financial system and we have exchange rate tables
which are updated with data every day.
Something like

create table TableDEF like TableX;

yes, you'd have to alter the queries to use the new index. As I say it's

For what it's worth, I get the same problem with 4.0.13, and have posted the
same question a few times with no response.
It works fine at the command line, but not through the mysql++ API.
It doesn't work on my home/work machines (both running XP), though my

Hi again, does the key page size differ depending on the type of the column
(BIGINT, INT, etc)? Is there any way I can work out the key page size, or
configure it?

is 200, log 200 (10^9) = 3.91
Splitting it into 10 smaller tables would make log 200 (10^9) = 3.47, which

We've had problems with a production database having indexes getting
corrupt. There are about 17 million records (500,000 new records a day)
in the table (MyISAM) and we run a delete script against it every night
to delete old data so the table doesn't get too big. We are running
