I am having problem with this MySQL error, if it is an error, - Current selection does not contain a unique column. Grid edit, checkbox, Edit, Copy and Delete features are not available. - My query is
SELECT INTERVAL a.seconds SECOND + CONCAT( DATE_FORMAT(CURDATE(), '%Y-%m-%d'), ' ', TIME_FORMAT(CURTIME(), '%H:%i:%s')) difdate FROM diffdate a
time_id is my unique and primary column
Please help. How can I resolve this problem?
Thank you.
