Below is the example that returns a difference of two date values, 2020-03-01 and 2020-03-10, in days: Query: select timestampdiff(day,'2020-03-01', '2020-03-10') AS result; Output:Discussion: To calculate the difference between the timestamps in MySQL, use the TIMESTAMPDIFF(unit, start, end) function. CREATE TABLE `contract` ( `id` int (11) NOT NULL AUTO_INCREMENT, `emp_id` int (11) DEFAULT NULL , `sign_time` datetime DEFAULT NULL , `end_time` datetime DEFAULT NULL , PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 ; CREATE TABLE. TIMESTAMPDIFF ('PERIOD',rc. I have a 'tasks' table that looks like the following: I need to calculate the start date offset for each record; I need to calculate how many days after the min/lowest start date the start date for each record is. TIMESTAMPDIFF.
