DATE_ADD(date, INTERVAL value addunit) Parameter: This function accepts two parameters which are illustrated below: date – Specified date to be modified. Improve this question. This time the issue is as a result of the way that WEEK interval works within the DATEDIFF function. One way around this is to use the builtin dummy table, dual: SELECT TO_DATE('2000-01-02', 'YYYY-MM-DD') - TO_DATE('2000-01-01', 'YYYY. mysql> SELECT DATEDIFF ('2010-11-30 23:59:59', '2010-12-31'); -31. Difference will be calculated as startdate - enddate . I have two columns that have time data that looks like "2017-12-06 18:50:27 +0000" . minute uses the hour and minute.
