I have a table with a timestamp field. How do I get data from the last 3 months?
In particular, March is my current month (03/2012). I need to return records from the months March, February, and January only.
3 months before today:
select * from table where timestamp >= now()-interval 3 month;
Start with first of month:
select * from table where timestamp >= last_day(now()) + interval 1 day - interval 3 month;
