SQL Insert Row as last RRN

I have a very simple 1-column workfile created on the fly with embedded SQL. As I add rows to the table, some situations require that some rows need to be deleted, which works just fine. But the next row added then gets stuffed into the workfile in the position (relative-record-number-wise) of the first row vacated by the delete. I didn't anticipate this when I designed my process, so I didn't build in a sequence number column. All the access to this workfile is through SQL - no RLA in this program.

Is there a way to specify on the INSERT statement that the new row is to have an RRN greater than that of the greatest RRN already written? If not, is there a simple way to re-sequence (compress) out the deleted rows after my DELETE statement, so that the result has contiguous RRNs (thereby leaving no gaps, and a subsequent INSERT would have to go to the "end" of the workfile)?

Thanks.
