How can i provide a seperator to the snmp traps in my database?

Question

I have a code that receives snmp traps. When the new traps come, i will save the output in database, as row data. Traps are coming one after another. In database they are mixed. it's confusing which trap values ​​it belongs to i cannot understand. What can i do for it, how can i seperate one trap from another in database? Here is my code

def cbFun(snmpEngine, stateReference, contextEngineId, contextName, varBinds,
          cbCtx):
    print('\n{0}New trap message received on {1} {0}'.format(
        '-' * 20,
        datetime.now().strftime('%d-%b-%Y at %H:%M:%S')))
    execContext = snmpEngine.observer.getExecutionContext(
            'rfc3412.receiveMessage:request')
    print('Trap is coming from %s:%s' % execContext['transportAddress'])
    for name, val in varBinds:
        print('{0} = {1}'.format(name.prettyPrint(), val.prettyPrint()))
        sql = "INSERT INTO snmp_log (name_oid, value_oid, date) VALUES (%s, %s, %s)"
        now = datetime.now()
        dt_string = now.strftime("%Y-%m-%d-%H:%M:%S")
        val = (name.prettyPrint(), val.prettyPrint(), dt_string)
        cursor.execute(sql, val)
        connection.commit()
    print('{0}Trap message ends{0}\n'.format('-' * 20))
