adding a field to mysql

I have an existing database. I can access it most easily with myphpadmin but i can also access it through the command line client. It has 2 tables. I was wondering whether I can add another field to the database. Will that create a problem for the existing records since they don't have an entry for the new field?

thanks.

I should do the
update tbl set newfieldname = 'existed'
immediately after creating the field right? If I wait and populate some new records this command will overwrite that field for the new records right?
Thanks.
