public function SelectExtender::getGroupBy in Zircon Profile 8.0

Same name and namespace in other branches

1. 8 core/lib/Drupal/Core/Database/Query/SelectExtender.php \Drupal\Core\Database\Query\SelectExtender::getGroupBy()

Returns a reference to the group-by array for this query.

Because this method returns by reference, alter hooks may edit the group-by array directly to make their changes. If just adding additional grouping fields, however, the use of groupBy() is preferred.

Note that this method must be called by reference as well:

$fields =& $query
  ->getGroupBy();

Return value

A reference to the group-by array structure.

Overrides SelectInterface::getGroupBy
