You may want to store the file extension as a separate field
in this table and index it. Then change your query accordingly.

Is it possible to query a tmp table that mysql creates automatically when
dealing with large queries?
When I do a 'show processlist' and it gives a state of 'Copying to tmp

the EXPLAIN query to make the output more legible.

I'm having a problem where a complex SELECT query begins eating up lots
of CPU and never returns. In "show processlist", it
reports "Copying to tmp table". Other queries seem to get locked
waiting for this query, as well.

So you have no redundancy? 5 arrays of raid 0 (2 disks each) = lose a
disk and your pooched..
suggestion:
reconfigure to raid 0+1 (more than 2 disks a set) for added perf ?

What steps can be taken to speed up queries that show state="copy to tmp
table" in show processlist? I am running MySql on a dual Xeon system
running Windows 2000 server with 10 10K rpm drives in 5 raid 0 arrays
and plenty of ram that isn't being utilized.

When I show my processlist, there is inner join query that having "Copying
