Hello Alexander, Try "define sql:log-enable NNN" at the beginning of CLEAR GRAPH statement. That will invoke log_enable (NNN, 1) before the operation (and restore the log mode back to original value after the operation). The log_enable() BIF is described in http://docs.openlinksw.com/virtuoso/fn_log_enable.html
