EamonSQL (10/24/2012)
select from the table using the ROW_NUMBER() function ordering by id and partitioning by value.
Wrap in brackets giving you a derived table.
Run a delete command against the table and joining to the derived table on the id and where rownum > 1
That should sort you out.

Don't you mean a COUNT(*), and deleting where COUNT(*) > 1?
