so here is his code...
SELECT TIMESTAMPDIFF(...) AS 'duration',
TIMESTAMPDIFF(...)
- INTERVAL 1 HOUR, TIMESTAMP(...)
+ INTERVAL CAST(...) AS 'timediff',
ris.ODATE as 'date',
CONCAT(...) as 'service'
FROM ... AS ris
JOIN ... as sd on ris.... = sd....
WHERE ris.... != '0000-00-00 00:00:00'
and ris.... != '0000-00-00 00:00:00'
and ris.... >= '2010-8-15'
and ris.... <= '2014-8-22'
so the timing for that is: 32.0460000038147
as far as what are the differences, well, web2py does open a transaction
and then close the transaction...
