Auto Update date Modified for DateTime field

The answer to this might just be that it can't be done but if I have a table with a datetime type field, that I want to automatically update whenever the record is updated.  Now if the type was timestamp this could be done as follows:


However I can't get this to work with a DATETIME field.  I have tried variations such as NOW in place of CURRENT_TIMESTAMP with no luck.

Presumably this can be done with triggers, but I'd like to be able to do it via the basic attributes.

unfortunately, the "trick" with ON UPDATE CURRENT_TIMESTAMP is not "portable" to datetime data type with NOW() function.
you HAVE to stick with timestamp, or use triggers
