3 Months previous data by given date mysql

Question

I have fee records in my database table. I want to fetch 3 months back records of the fees in database. I am using:

SELECT * FROM fee_challans
    WHERE student_id = 630
    AND STATUS =  'un-paid'
    AND DATE_FORMAT( fee_date,  '%Y-%m-%d' ) - INTERVAL 2 MONTH 

This query that I searched and found on google.

Answer 1

You forgot to compare your column to something...

SELECT * FROM fee_challans
    WHERE student_id = 630
    AND STATUS =  'un-paid'
    AND fee_date >= CURDATE() - INTERVAL 3 MONTH;

And if your fee_date column is of type date , datetime or timestamp , date_format() is not necessary.
