In my experience this happens a lot if you put application programmers in
charge of the database. I've upset quite a few in my time by introducing RI
and then their horribly coded application falls over!

Hey there, thanks for your comments. There are issues where sharding may
be appropriate, but you are talking about the heaviest of heavy duty
loads. Not only that, hardware is getting to the point where it is
surpassing our needs. Remember the days when it cost $200k to run a
library database?
Hi All,
We are using 5.0.40-enterprise-gpl-log version on our production db. If we

Hi all,
I'm new to the list so please excuse me if I make some newbie
mistakes, I am having trouble figuring out why a select statement
won't work, Here's the statement: SELECT 'FName' FROM `current`
WHERE `FName` like '%jason%';.
if I run select 'FName' FROM current; then I get 6 rows

Have you tried using 'jason%' instead of '%jason%'? Also, do you have
an index on that column?

This should do it. Save it in a file then run it like perl newfile.pl.
Save the output into a text file, then run it against your database.
$records = 100;
for ($i=1;$i=$records;$i++) {
print INSERT INTO MyTable (forumid, styleid, title, title_clean, .
description, description_clean, options)

Thanks for your help. I'm not able to ssh into this box - how can I run

You can generate data by using a stroed procedure, too. I prefer this
method because it doesn't
Say I have x rows of 2 columns each.
For example, 2 rows: 'A 10:00pm' and 'A 11:00pm'.
I want to return one 'A' row with the latest time (eg. 'A 11:00pm).
I could do 'select distinct(col1) from table' and then 'select
col1, max( col2 ) where col1=row[0]'?
Is there a way to do it in one

It is my contention that as the clustering capabilities of MySQL
continue to grow and mature (think of when version 6.0 goes stable)
companies will move to MySQL in droves. THEN you have the ability to
build a single virtual database (at least from the point of view of
your application)

I'm trying to construct a join, but the effect I want seems
to be impossible to achieve. In this schema, the uid
field is unique in the players table, but not in the ranking
table (one player per uid, multiple rankings per player)

Lets hope something is done about it soon, not all sub queries SHOULD be
re-written as joins. Generally joins that result in the need to use
DISTINCT are better off re-written as IN OR EXISTS sub queries.
In any event, I have a lot of very complex queries that work great for
our other database
