"The following SQL script will remove duplicate rows from the table specified by the parameter &1, where the duplicate rows are defined by identical values for the column-list defined by the parameter &2:

DELETE FROM &1
WHERE
 ROWID NOT IN (
    SELECT MAX(ROWID) FROM &1
    GROUP BY &2
    )
/ "

Problem solved now?
