question about datetime type default

[nephish]

Hey there, i know this is more of a MySQL question, but did not know where to put it.

i have a database with about 20 tables. The some of these tables have
datetime type columns in them. What i am basically wondering is if
there is a way to make a default value of now() apply if it is not
specified when the row is created.
i know this is possible with a timestamp, but is it possible with a
datetime column ? and if so, how ?

thanks

any particular reason you don't just use TIMESTAMP types?

If it's a question about databasing, why not put it in the database forum?
