Question

Ok, an old hack is no longer working. Currently using MySQL 5.5.11

In my table I have the below in the same order.

created TIMESTAMP NOT NULL DEFAULT 0000-00-00 00:00:00
updated TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP

On INSERT everything works correctly and NOW() is inserted on both created and updated

Now with MySQL 5.5.11 when I UPDATE, updated works correctly but I loose created (reverts back to 0000-00-00 00:00:00)

How can I overcome this limitation with MySQL’s lack of multiple TIMESTAMP support?

Answer 1

Yes, it would work on earlier version, but not newer version.
I believe you can solve this as follows:

`created` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,

And then create an trigger BEFORE UPDATE on [updated] column.

SET new.updated = now();

Or vice-versa.
