Now that I use mysql at $work these mysql behaviour s worry me a lot more but at least this is one mysqlism I'm not likely to fall into. I do not expect to be counting nulls in a not null table.

  Plus, in what way is '0000-00-00' a valid date? I can only see it as a (badly) stringified version of a NULL date. Thus, it should have been disallowed as an entry in this table. IMO it should be disallowed anywhere.

    '0000-00-00' is a valid "zero value" date in MySQL - see the docs [mysql.com] for the evil details.
    
    Needless to say - not my schema.
