If surname is a field, then use it without the single quotes ('),
otherwise it is treated as a literal string and 0 is the correct result:
select locate(' ',surname,1) from advisers

What is the rule of thumb to use?

well, it seems to be fine without SUM and GROUP BY...
E.g.,
SELECT @a:=Charge, @b:=Cost, @[EMAIL PROTECTED] as Margin ...
produces expected results.

Start another Mysql shell session; then do show processlist; identify
the thread ID of the offending process, then do kill ID. Not sure
how graceful this method is, though. I use it to kill overlooked hanging
connections from time to time.

Hi all,
Just noticed that a simple query that returns only 14 rows is 10X slower
when ORDER .. DESC is used compared to ORDER .. ASC.
The table has about 700,000 records, indexed on the field the table is
being ordered by.
Is this expected behavior?
MySQL 4.0.18 running under OpenBSD 3.4
The timing is consistent both ways - have tried both queries back-to-back
alternatively many times. I'm pretty sure that it is not caching that causes the
discrepancy.
So, this turns out to be a known issue after all... Somehow I missed it. Thanks, Donny!

have a new
portion of data to be uploaded, first you have to start Perl, then have
it load the script, then establish a new connection to the DB server -
all these steps are totally redundant, but they do overload your box.
Hope this helps.

Just a thought - if your serial numbers have fixed format, then
programmatically remove the hyphen and store the number without it. Add it
back when displaying data on the screen. That way FULLTEXT will work on the
whole number without splitting it into two parts.

Put parentheses around the ..OR.. part (between WHERE and AND) - AND precedes

Also, use 'IN' instead of a series of 'OR' - this will make the query a lot
