How can I add (minutes / hours / days / months / years) to date in INSERT
INSERT INTO sample_table(value,expire) VALUES("Some text", NOW() + 4 MONTHS)
(SQL query or in PHP)
You need to use the DATE_ADD()
function like so:
INSERT INTO sample_table (value, expire)
VALUES ("Some text", DATE_ADD(NOW(), INTERVAL 4 MONTH));
It also works with other intervals such as the intervals that you requested in your question
You can find more about the DATE_ADD()
function here:
https://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_date-add
You are missing the interval
keyword:
INSERT INTO sample_table(value, expire)
VALUES('Some text', NOW() + INTERVAL 4 MONTHS);
