000000 is not a valid date, as you are aware :) This is often solved in
the application layer by preprocessing the data, changing 000000 to
NULL, for example. You may be able to do some of this preprocessing in
the database itself, first loading the raw data into a temporary table
and then transforming it before putting it into the desired table.
