Is there a way to only include certain matching conditions
in indexes?
Example if I have a row I want to index that is mysql dates
(2007-06-07) and I only want to include CURRENT and FUTURE

The issue I have is that the
We have a statement that joins 8 different tables to pull
multiple rows from each table.
I have heard of people using triggers to create, update and
delete records in a table based on statements in other
tables.
The obvious result of this would be to SPEED up results
right? :)

I'm having an issue where an application will open multiple

Eventually, the server will get bogged down with these
connections or reach the max connections and stop allowing

If you are using PHP, Please make sure you close all
mysql_query requests with two(2) calls
I use SQLBalance for MySQL.
It's got a couple of minor bugs, but it's been great for us.

Omnipilot, the makers of the LASSO application server now offer a free
developer version of lasso professional. It has the best web-based database
browser and SQL utility that I've ever seen. It has native MySQL connectors,
it's a snap to get up and running.

I've heard absolutely wonderful things about this transaction-safe storage
engine. We're using InnoDB now and are always looking for the best solution
as we scale our DB operations.
Has anyone tried the SolidDB for MySQL beta stuff yet?
What do you think of it?
Cory.
Slightly new query.. Here's the new query and results of an explain..
I'm thinking that some indexing would help.. However, I don't really
know where to start.

It seems to me that this is something that is going to become more and more
popular so I'd be really surprised is MySQL-AB isn't already cooking

If you do go the new hardware route, I wouldn't go with SCSI is you
only have $2K to spend. S-ATA2 based drives would give you similar

I'm trying to return all records between two dates.. The fields are

Which is better? The following or using BETWEEN? (A little lost here)
