MYSQL - multiple count statments
I'm trying to do a lookup on our demographioc table to display some stats. However, since out demographic table is quit big I want to do it in one query.
There are 2 fields that are important: sex, last_login
I want to be able to get the total number of logins for various date ranges (<1day ago, 1-7 days ago, 7-30 days ago, etc) GROUPED BY sex
I right now know how to do it for one date range. For example less than 1 day ago:
SELECT sex, count(*) peeps
FROM player_account_demo
WHERE last_demo_update > 1275868800
GROUP BY sex
Which returns:
sex peeps
----------------
UNKNOWN 22
MALE 43
FEMALE 86
However I'd have to do this on开发者_如何学Cce for each range. Is there a way to get all 3 ranges in there?
I'd want my end result to look something like this:
sex peeps<1day peeps1-7days peeps7-30days
Thanks!
IMPORTANT NOTE: last demo_update is the epoch time (unix time stamp)
SELECT sex,
SUM(IF(DATEDIFF(NOW(),last_login) < 1,1,0)),
SUM(IF(DATEDIFF(NOW(),last_login) BETWEEN 1 AND 7,1,0)),
SUM(IF(DATEDIFF(NOW(),last_login) BETWEEN 7 AND 30,1,0))
FROM player_account_demo
GROUP BY sex
You want to use a Pivot Table.
