Class Phalcon\Mvc\Model\Query

implements Phalcon\Mvc\Model\QueryInterface, Phalcon\Di\InjectionAwareInterface

Source on GitHub

This class takes a PHQL intermediate representation and executes it.

<?php
$phql = "SELECT c.price*0.16 AS taxes, c.* FROM Cars AS c JOIN Brands AS b
         WHERE b.name = :name: ORDER BY c.name";
$result = $manager->executeQuery(
    $phql,
    [
        "name" => "Lamborghini",
    ]
);
foreach ($result as $row) {
    echo "Name: ",  $row->cars->name, "\n";
    echo "Price: ", $row->cars->price, "\n";
    echo "Taxes: ", $row->taxes, "\n";
}
