Yes, you're right, with that index query is flying...
then I used DAYOFMONTH(calldate) instead of DATE_FORMAT(calldate, '%d'),
it gives an extra performance gain of 5x
tnx for help

Tnx for your precious advice.
Do you know if there is some documentation somewhere on the net with the
most known Innodb performance limitations ? so I can avoid to teast
again each query and doing different optimization.
I tried the original query with 5.0 and 5.1... same results...
Tnx

Yes, Falcon is a great piece in the MySQL arsenal if you ask me (or

Hi,
I found one thread on this that included some people's opinions, but I
haven't been able to find anyone who has actually done some performance
testing to see if there is a cost and what that cost is to doing cross
database joins. I do tend to want to keep everything in one DB, but it
surely mysql would just fork the last gpl innodb release if they got
bummed by oracle...

I doubt if they can -- from the InnoDB website:

Hi everybody,
Does different table space with multiple databases is good for production
server. Is there any testing has been done. What is the impact on the other
things like speed.
Thanks,

You need to use replication not mysql-table-sync for replication.
mysql-table-sync is use to get it back in sync.

Hi,
I wouldn't say the Sleepycat/BDB acquisition had anything to do with
MySQL. BDB is much more useful *outside* of MySQL, and has a much
bigger market there anyway. The BDB storage engine is all but useless.
As for Innobase/InnoDB, their motives are still unclear. :)

Hi all,
Wow, the rumors were true. Oracle is snapping up Open Source Database
companies now. First it was Innobase (see Oracle buys Innobase. MySQL
between rock and hard place?) and now it's Sleepycat Software.
The purchase of Sleepycat, which has been rumored for weeks, gives
Oracle another
Does all these reasons brings oracle massive on Global market.. compared
to other databases...?

we have a column in a table, called tag numbers, which start with numerical and

now what I need to do is to display all the tag numbers, but order by their

Craig,
I have my doubts about Falcon replacing InnoDb. I don't think it
will be fast enough to handle a lot of users.
As to why
The second query might be faster due to caching.
