If you use ROLLBACK in a BTEQ script with either the .SESSION or the .REPEAT command, you must send the ROLLBACK statement and the repeated SQL statement as one request.

If you send the repeated request without the ROLLBACK, one of the requests is eventually blocked by other sessions and the job hangs because of a deadlock.
