Specifies that Oracle Rdb delete rows after they have been
    unloaded from the database. You can use this qualifier with the
    Commit_Every qualifier to process small batches of rows.

    If constraints, triggers, or table protection prevent the
    deletion of rows, the RMU Unload operation will fail. The Delete_
    Rows qualifier cannot be used with non-updatable views, those
    containing joins, or aggregates (union or group by).
