WH         


        

Answer 1

You could do like that :

SELECT COUNT(id), DATE_FORMAT(`timestamp`, '%Y-%m-%d %H:%i')
FROM `table`
WHERE `timestamp` BETWEEN (DATE_SUB(NOW(),INTERVAL 5 MINUTE)) AND NOW()

Answer 2

Current_timestamp returns the current date as a SQL TIMESTAMP, not a UNIX timestamp, so you'd have to convert using the unix_timestamp function:

SELECT COUNT(id), from_unixtime(`timestamp` / 1000, '%Y-%m-%d %H:%i')
FROM `table`
WHERE `timestamp` >= unix_timestamp(CURRENT_TIMESTAMP - INTERVAL 5 MINUTE) * 1000

EDIT:

As your timestamp column contains unix time, you're also going to have to use from_unixtime to format the date.

EDIT2:

In MySQL UNIX time is the number of seconds since epoch (1/1/70), so if your timestamp column contains the number of milliseconds, you'll have to divide by 1000 as well.
