How to update all objects with SQL?

[Friendly]

I am trying to make 14 day maintenance on my server but dont want to instantly add it because then peoples bases will just dissapear. IS there a sql that I can enter to update when everything was made so that when I add it, everything starts at day one.

UPDATE Object_DATA
SET Datestamp = CURRENT_TIMESTAMP
SET LastUpdated = CURRENT_TIMESTAMP

Error:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET LastUpdated = CURRENT_TIMESTAMP' at line 3

:)  I was swinging it from the top of my head. How about this.

UPDATE `object_data` SET `Datestamp` = CURRENT_TIMESTAMP
UPDATE `object_data` SET `LastUpdated` = CURRENT_TIMESTAMP

Run those 2 lines separately, not in same query.

Or with an ';' between the 2 lines.
