This is an example outlining how a module can make use of the DBTNG database API in Backdrop.

Code

function dbtng_example_entry_update($entry) {
  try {
    // db_update()...->execute() returns the number of rows updated.
    $count = db_update('dbtng_example')
      ->fields($entry)
      ->condition('pid', $entry['pid'])
      ->execute();
  }
  catch (Exception $e) {
    backdrop_set_message(t('db_update failed. Message = %message, query= %query', 
    array('%message' => $e->getMessage(), '%query' => $e->query_string)), 'error');
  }
  return $count;
}
