Brian,
I think the answer is to create a sub query,
Without your tables I can't test this transcription, but the trick is
straightforward: if the first query includes the column(s) required to
join it correctly to the 2nd query, replace the avgscore table reference
in the second query with
In a nutshell, one way to do subqueries is to just name the query and join on
it as if it was a regular table.
SELECT field1,field2,... FROM table1
INNER JOIN table2 ON field1=fieldT2

I would be thrilled if someone could even just point me to a site that
provided good examples of using sub queries. I have the following query:
SELECT
participants.store_id,
completed_modules.module_id,
AVG(completed_modules.score) AS AVGSCORE
FROM

As for question 1: the overhead will be exactly the same in both index

what accelerates application quiries most effectively.
Question 2: by all means, add the
I have two questions about the overhead associated with updating the
indexes when records are added, deleted or modified. Lets say I have a

distinct values).

Hello,
Good post, but not what i'm looking for.
Well, Postgresql seems to be the winner, at least for
handling network addresses.

Thanks.

(restarted it) and changed my php command to:
$mysqli = new mysqli(".", $username,$password, $database);
and all seems to be working fine now.
Thanks again for your help, much appreciated.
