Can this be done in one SQL statement with the result placed back in WORKFILE1?

Or should I create a new table QTEMP/WORKFILE2 using DISTINCT or GROUP BY, and then CPYF back to WORKFILE1.

Another option being to create a new file delete the old one and either move or rename the new one to the old name. Neither move or rename would actually move the data so both should be more efficient than copying the new on back again.
