Running an SQL delete will actually delete each row, row by row

Just FWiW...

The member remains the same object, as does the dataspace. That can be confirmed by DMPOBJ showing the same address of the *MEM and the *QDDS objects both before and then after the CLRPFM request. The dataspace object is truncated by a request to clear the PF member; the individual data segments [those addresses not visible in the dump object] returned to the system\ASP.

The member.data will have the deleted rows remaining [and thus taking up disk space, until reorganize PFM] irrespective of the reuse-deleted attribute setting; except of course, with the capability of the SQL DELETE to implement using the "clear" feature [Fast Delete support] which was already noted in a response by Eric DeLong.
