Question

I have the following MySQL query, and I’m trying to adjust it so it only fetches results which are within the current month (of the current year), I’m guessing you may require more info about my MySQL structure so here it goes – I have a UNIX timestamp generated by PHP’s time() stored within the time column (under the referrals table), so with the below setup it would be t2.time.

So my problem is I’m unsure how to proceed, I’m guessing it would be something like adding the following to end of the WHERE clause? => AND t2.time IS WITHIN THE CURRENT MONTH (caps are just on to distinguish problem from rest of query) but i’m not sure how to check if its within the current month.

The MySQL Query:

SELECT t1.username,
       t1.website,
       SUM(IF(t2.type = 'in', 1, 0))  AS in_count,
       SUM(IF(t2.type = 'out', 1, 0)) AS out_count
FROM   users AS t1
       JOIN referrals AS t2
         ON t1.username = t2.author
WHERE  t1.website != ''
GROUP  BY t1.username,
          t1.website
ORDER  BY in_count DESC 
LIMIT  0, 10 

Appreciate all help! :B

Answer 1

you can use from_unixtime like

date_format(from_unixtime(t2.`time`), '%Y-%m')=date_format(now(), '%Y-%m')

But I think data type integer is not so suitable for this requirement

I would think using datetime will be more suitable, built an index on this column and this also make the filtering easier, like

t2.`time`>='2011-01-01' and t2.`time`<'2011-02-01'

or

date_format(t2.`time`, '%Y-%m')=date_format(now(), '%Y-%m')
