Need Qry Syntax Help - Need to delete two records that are exactly the same

I accidentally inserted two records that are exactly the same into a MS SQL (2005) table.  I can't delete them using the following qry:

Delete from Competitors where CompetitorID=66 and SeasonID=12 and EventID=0 and RunID=6

When I run the qry, it says 0 rows affected.  The only way I know how to fix this is truncate the table and then reinsert the data.  Is there another way, because there is no way I want to risk the data.

Thanks in advance!

Regards,
Eric

then, your where clause is not correct.

can you please show the query that returns the data of the 2 rows (SELECT)?
I would use the following technique to delete a single row (even if there are several rows):
SET ROWCOUNT 1
DELETE Competitors  WHERE ...
SET ROWCOUNT 0
0

If you are sure that these are the identifying values for these columns for the rows in question then it looks like you don't have the problem you think you have.  Change the "Delete" to a "Select * " in your SQL statement and see whether in fact you still have the troublesome rows in your table, i.e.

Select * from Competitors where CompetitorID=66 and SeasonID=12 and EventID=0 and RunID=6
0
