You could also try the following approach:
- on the table, have an INSERT trigger add the username to a column
named CREATE_WHO (this can be extended to UPDATE operations too, but
this probably isn't necessary in your example)
- create a view based on "select * from table where CREATE_WHO =
SUBSTRING_INDEX(USER(),'@',1);".
- DML statements are now applied against the view, and not against the
underlying table.
This depends on the user who is logged in to the DB though.

Hope this helps,
Paul
