SET SESSION TRANSACTION ISOLATION LEVEL READ UNCOMMITTED; START TRANSACTION; SELECT count(*) as cnt, sum(size) as vol, ROUND(LOG(10,UNIX_TIMESTAMP(NOW())-last_access),0) as logage FROM ENTRIES group by logage; COMMIT; Displaying LOG(N) of age is convenient to deal with a wide range of dates. If you want more or less values in your output you can change the first log parameter (10 in my example). Here is an example of output: +---------+-------------------+--------+ | cnt | vol | logage | +---------+-------------------+--------+ | 7 | 5157043497 | 1 | | 4042 | 142109394704 | 2 | | 25606 | 1269601700899 | 3 | | 146951 | 4789029277529 | 4 | | 32819 | 39290924149114 | 5 | | 386692 | 407028626133397 | 6 | | 2358308 | 4458175715745348 | 7 | | 7831503 | 13112482439101033 | 8 | | 24785 | 15406928299641 | 9 | The related age for each row is around "age^10" (in seconds). "SET SESSION... / START ... / COMMIT " all this stuff is to avoid an agressive locking of the whole robinhood DB while robinhood is currently working on it!
