SelectInterface::getGroupBy

public &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.
