public function SelectInterface::getExpressions
public &SelectInterface::getExpressions()
Returns a reference to the expressions array for this query.
Because this method returns by reference, alter hooks may edit the expressions array directly to make their changes. If just adding expressions, however, the use of addExpression() is preferred.
Note that this method must be called by reference as well:
$fields =& $query->getExpressions();
Return value
A reference to the expression array structure.
