Hi,
I'd really appreciate help with reading this db deadlock notice.
Essentially, I'd like to understand:
-what holds the lock that TX2 is waiting on index `token` of table
`eviltwin/user_sessions`? I thought it'd be TX1 (hence deadlock ?), yet
it appears that TX1 holds no locks
-if the an
I think you're approaching this from the wrong angle. You'll want to put
the data at the highest level at which it changes.
i.e. If every song on an album is always the same year, put it at the
album level, however, if it changes from song to song on a particular
album, then you want it at the
So I'm currently designing a database for a web site and intra net for my
campuses student radio. Since I'm not getting paid for this and I'm doing
this in my free time I kinda want to take my time and have the system setup
as "perfectly" as any one college student can.
I'm currently debating on
Yes. It only reports the changed rows.

I think you're right and using an IF is ultimately the right answer.
However just substituting issuenum for issuedate doesn't do the right
thing.
Looking at my sorting a bit more analytically I think that what I need
to do is, WHEN there isn't a month number, THEN substitute the
existing month nu

Ben,
Check out Linux-ha ( http://linux-ha.org). We are using version 1 at my
company, which is fairly easy to set up and there are a lot of good articles on
it. With this you can create a virtual address to fail-over between systems,
run commands / scripts during a fail over, and even kill
I have a need to output a recordset that shows the record with the
higest value for severity within a date range. That is easy enough, but,
in the same query, I need to show that data 3 times in the same query.

That should be fairly easy. What you are looking to do is have your sort field conditional. The ORDER BY doesn't have to specify a
database field, it can be any field in your query. So you could do something like this:
SELECT IF( issuemonth IS NULL, issuenum, issuedate) AS sortfield, issuedate,

Hi Andrew,
Since the default storage engine is myisam, increase the below parameter and
then try your index operation.

myisam.
Also
Set key_buffer to 5 - 50% of your RAM depending on how much

The first part of the WHERE clause gives you the week number of a record's
date, and compare it with today's week number. Note that
WEEK("2008-01-01",7) will return 53, indicating that because 2008-01-01 is a
Tuesday it is part of the last week of 2007. That, I think, is what you
