Question

I have a DB with many tables and one of the table has fields:

id—-number—–start—–end

Start corresponds to date and time of process: 2012-06-08 01:16:07

End correspond to end of the process : 2012-06-08 01:39:47

I need to count all the processes that were in the previous 4 weeks, with a duration of above 10mins…..Just the no: processes is enough.

A php querying from the DB is required.Tried in a few ways but dint even get near. How do I do that?

Answer 1

SELECT COUNT(*) AS 'processes' FROM table1
WHERE TIMESTAMPDIFF(MINUTE, start, end) > 10
AND start BETWEEN DATE_SUB(NOW(), INTERVAL 28 DAY) AND NOW()
