MySQL Timestamp - why all zeros?

Question

I\'m using PHPMyAdmin and I\'ve got a MySQL table column called \"timestamp.\" The type (surprise!) is TIMESTAMP, and in \'attributes\' I\'ve set it to ON UPD

Answer 1

If your timestamp column captures only the insertion time then use only

timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP

Otherwise if it is for modification time then use like as follows

timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
