Hi Abu ,

I have a problem with large database and some querys in phpgrid.

one of the query that take long time to load

SELECT s.seq_number,a.ticket_number,a.ticket_total,a.terminal,a.operateur_id,(SELECT FROM_UNIXTIME(a.date, '%Y-%m-%d %H:%i:%s')) as valdate
FROM (SELECT seq_number FROM moprop WHERE MOP IN (1)) s
INNER JOIN ticket a ON a.seq_number = s.seq_number
INNER JOIN items b ON b.seq_number = s.seq_number
WHERE b.crd IN (425,335,225) LIMIT 100 OFFSET 0

Each table is +/- 4-5 million records

query directly from phpmyadmin take 0.14 sec to load page

from phpgrid ( i remove LIMIT 100 normally replaced by $grid["rowNum"] = 100)
i take more than 2 minutes to load page.

any ideas ?

Thanks

Hello,

I cannot generate exact setup and db here, I would need remote session to review this case.
Let me know your feasible time and working timezone.

I'll check this case remotely.
