With the help of following example we can understand that how we can use MySQL INTERVAL keyword with EXTRACT() function −
mysql> Select StudentName, RegDate, EXTRACT(YEAR from RegDate+INTERVAL 2 year) AS 'Two Year Interval' from testing where StudentName = 'Gaurav'; +-------------+---------------------+-------------------+ | StudentName | RegDate | Two Year Interval | +-------------+---------------------+-------------------+ | Gaurav | 2017-10-29 08:48:33 | 2019 | +-------------+---------------------+-------------------+ 1 row in set (0.02 sec)
Above query is showing how we can use INTERVAL keyword with EXTRACT() function used in MySQL table query.
mysql> Select EXTRACT(Year from '2017-10-22 05:03:45' + INTERVAL 2 Year) AS 'Two Year Interval'; +-------------------+ | Two Year Interval | +-------------------+ | 2019 | +-------------------+ 1 row in set (0.00 sec)
Above query is showing how we can use INTERVAL keyword with EXTRACT() function used for particular given date.
