Question

Something like:

SELECT MONTH(*date?*)
  FROM 
   //Not sure what goes here
LIMIT 0,6

I know its simple, but I want to know how to get a list of the last six months in case i ever need to Join to it. Useful if getting past data and using:

IFNULL(data, 0)

Answer 1

select month(DATE_SUB(now(), INTERVAL 6 MONTH)) month_6,
       month(DATE_SUB(now(), INTERVAL 5 MONTH)) month_5,
       month(DATE_SUB(now(), INTERVAL 4 MONTH)) month_4,
       month(DATE_SUB(now(), INTERVAL 3 MONTH)) month_3,
       month(DATE_SUB(now(), INTERVAL 2 MONTH)) month_2,
       month(DATE_SUB(now(), INTERVAL 1 MONTH)) month_1

OUTPUT

month_6 month_5 month_4 month_3 month_2 month_1
      9      10      11      12       1       2

If you want it to include the current month, then just start with 5 and go to 0 instead of 6 to 1.

If you want rows, do this:

select        month(DATE_SUB(now(), INTERVAL 6 MONTH))
union  select month(DATE_SUB(now(), INTERVAL 5 MONTH))
union  select month(DATE_SUB(now(), INTERVAL 4 MONTH))
union  select month(DATE_SUB(now(), INTERVAL 3 MONTH))
union  select month(DATE_SUB(now(), INTERVAL 2 MONTH))
union  select month(DATE_SUB(now(), INTERVAL 1 MONTH))

OUTPUT

9
10
11
12
1
