Code

public function query() {

    ->ensureMyTable();

    'table' => 'users_field_data',
    'field' => 'uid',
    'left_table' => 'comment_entity_statistics',

    ->createInstance('standard', $definition);

  // @todo this might be safer if we had an ensure_relationship rather than guessing
  // the table alias. Though if we did that we'd be guessing the relationship name
  // so that doesn't matter that much.
  $this->user_table = $this->query
    ->ensureTable('ces_users', $this->relationship, $join);
  $this->user_field = $this->query
    ->addField($this->user_table, 'name');

  // Add the field.
  $this->query
    ->addOrderBy(NULL, "LOWER(COALESCE({$this->user_table}.name, {$this->tableAlias}.{$this->field}))", $this->options['order'], $this->tableAlias . '_' . $this->field);
