SQL Auto-Increment by DateTime

Question

Is there a way in my sql to auto increment by the date and time?

so say I have a table

                         mytable
 ============================         


        

Answer 1

Run this in your MySQL:

ALTER TABLE `mytable` 
CHANGE COLUMN `DateTime` `DateTime` TIMESTAMP NULL DEFAULT CURRENT_TIMESTAMP ;

This sets your default value to CURRENT_TIMESTAMP.

Answer 2

You can set a default value for your datetime column, now(). This way whenever you add a row, it will automatically get current datetime.
