Auch, thanks for pointing that out, what a terrible mistake.
I am aware of the performance issue, and so is the customer. But with a
table that's only going to hold maximally 60.000 records in 10 years,
I'm not afraid it'll cause significant problems. If it gets out of hand
we'll have to

Hi John,
OK, no conspiracy here. Here is your problem:
25 $qry = sprintf(SELECT id, line FROM `encryptietest`
WHERE AES_DECRYPT(`field`, '%') LIKE '%%%s%%', $enckey, $word);
You are missing the s in %s for your first string argument, which
causes the query to be syntactically
Have you tried reversing the order of your tests, to see if there is some
influence from caching?

Hi John,
Your attachment for the php code got stripped somewhere. Can you post
it somewhere (http preferable)? In either case it's going to result in
a full table scan, so they are actually both a bad strategy long term,
but they should in theory perform as you would expect, with with
Thanks a lot!! :D
You were right. There was a bug. Upgrading to mysql 4.1.20 solved my
problem.

Hi, List!
I'm a little bit confused with (IMHO) poor query performance.
I have a table with 1'000'000 records.
Table consists of 2 service fields and a number of data fields. Service
fields are status and processor_id (added for concurrent

Hi:
Let's say I want to store the following information.
Unique ID - INT(10) autoincrement
First Name - VARCHAR (25)
Last Name - VARCHAR (25)
Age - INT(3)
In general 'age' is a bad column, because you need to know what year the
data was entered to calculate the current age.

You could probably save a bit of processing time by changing:
concat(date_format(from_unixtime(time), %d/%m/%Y), - ,
time_format(from_unixtime(time), %H:%i))
to:
date_format(from_unixtime(time), %d/%m/%Y - %H:%i)
This would mean half the date conversions would be executed.
Separating out the
If you do I suggest you also include relevant table definitions and
possibly a little sample data (plus an indication of total table
sizes) and expected output, this will greatly assist anyone who my be
