get last three month records from table

How to get last 3 months records from the table.

SELECT * 
from table 
where month > CURRENT_DATE-120 
  and month < CURRENT_DATE 
order by month;

I have used the above query is it correct? shall I use this for get last 3 month record from the table.

Solution

  • You can use built-in INTERVAL instruction

    Check how this works:

    SELECT CURRENT_DATE - INTERVAL '3 months'

    and you can rewrite your SQL to:

    SELECT * from table where date >  CURRENT_DATE - INTERVAL '3 months'

    (not checked but this should give you an idea how to use INTERVAL instruction)
