public function SelectInterface::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.
