Date Functions in MySQL

Question

Looking for some help regarding mysql date functions.

I am looking to show data for a time period of today to 8 days ago (I have been using this line of code in mysql WHERE TIME > CURDATE() - INTERVAL 8 DAY ) ) as well as the above time period but one year ago.

Answer 1

Try using DATE_SUB with TIMESTAMPDIFF,

TIMESTAMP syntax,

TIMESTAMPDIFF(unit, datetime_expr1, datetime_expr2);

DATE_SUB syntax,

DATE_SUB(date, INTERVAL value unit);

---

Example,

SELECT TIMESTAMPDIFF(SECOND, DATE_SUB('2018-06-04 22:59:00', INTERVAL 10 DAY), 
 '2018-06-04 22:59:00');
