The parts I am interested in:
(I won't bore you with the fields not relevant to this problem )
CREATE TABLE events ( e_id int(15) NOT NULL auto_increment, e_owner int(15) NOT NULL default '0', e_time int(15) NOT NULL default '0', ....other junk omitted.... PRIMARY KEY (e_id) ) TYPE=MyISAM;
Thanks.... And I am liking that other answer although it has all nulls in the second owner column and I don't get how it works.
When I write applications that delete I always back up the table and use a copy or a small sample on a play database.

If you post the table structure (SHOW CREATE TABLE tablename\G) we could help you write this statement.
