Question

So i have 2 tables in each row, i used this to get the avg time in minutes.

SELECT Sec_to_time (Avg (Timestampdiff (second, `survival`, `lastupdate`)))
FROM   main

But i want to get the hours, minutes, and seconds alone so i can echo them in php.

Answer 1

You can use the MySQL HOUR(), MINUTE() and SECOND() functions to break the time returned from SEC_TO_TIME into its components.

To avoid having to repeat yourself, you can wrap the calculation:

SELECT HOUR(x.timeDiff), MINUTE(x.timeDiff), SECOND(x.timeDiff) 
FROM 
  (
    SELECT Sec_to_time(Avg (Timestampdiff (second, `survival`, `lastupdate`))) as timeDiff
    FROM main
  ) AS x
