Deleting one of 2 identical records

["Gauthier, Dave" <dave.gauthier@xxxxxxxxx>]

Hi:

 

If I have a table that has 2 records which are identical with regard to all their column values, is there a way to delete one of them, leaving one remaining?  Is there some unique record_id key of some sort I can use for somethign like this?

 

Thanks in Advance!
