I have a 6 numeric character field in a table that is supposed to be a 
date value in the format of 'mmddyy'.  But a small percentage (5 out of 
2.5 million for my first sampling) are not actually data recognizable as 
a legitimate date.

Is there any way I can easily query the data for records with a value 
that can *NOT* be converted into a date in the format of 'mmddyy'?  In 
other words is their anyway to do something like an exception trap on 
the to_date(field,'mmddyy') function to return records that will fail it?

TIA
Ian
