[SOLVED] MySQL select all rows from last month until (now()

MySQL select all rows from last month until (now() - 1 month), for comparative purposes

I need some help writing a MySQL query to show me rows from last month, but not the whole month, only up and until the same day, hour and minute as it is now(), but 1 month before.

So for example, if today is 5/19 at 5:25pm I need to select rows from midnight 12:00am 4/1 to 5:25pm of 4/19 (from the same year too of course).

Thanks!

Solution

You can get the first of the month, by calculating the last_day of the month before and add one day. It is awkward, but I think it is better than formatting a date as string and use that for calculation.

select 
  *
from
  yourtable t
where
  /* Greater or equal to the start of last month */
  t.date >= DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 2 MONTH)), INTERVAL 1 DAY) and
  /* Smaller or equal than one month ago */
  t.date <= DATE_SUB(NOW(), INTERVAL 1 MONTH)
