FYI, You're suggestion worked fine. I'm not entirely convinced I'm doing
this sanely still, but it does work.

I also do this to calculate a read_size column which has the formula of
(read_bytes/read_ops = read_size). Note that read_ops could be 0 which
would yield a NULL in the read_size column. To avoid that, I use a
nested IF!

IF(SUM(IF(latx_stats_data.statname = 'read_ops', `statval`, 0)), 
(SUM(IF(latx_stats_data.statname = 'read_data', `statval`, 0)) /
SUM(IF(latx_stats_data.statname = 'read_ops', `statval`, 0))), 0) AS
'read_size'

I have to do this with several columns. I wonder if should read up on
stored procedures...
