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

What am I missing?

You don't update :)

Use DEFAULT CURRENT_TIMESTAMP along with ON UPDATE CURRENT_TIMESTAMP

Answer 2

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

Answer 3

Try setting the default value to CURRENT_TIMESTAMP instead of putting that in the attributes.

MySQL Reference

Answer 4

In my case works like this:

In phpMyAdmin:

ALTER TABLE `name_table`  ADD  `name_row` TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP;

In PHP sintax for the row:

date('Y-m-d H:i:s')
