Abstract class Phalcon\Mvc\Model\Query\Lang

PHQL is implemented as a parser (written in C) that translates syntax in that of the target RDBMS. It allows Phalcon to offer a unified SQL language to the developer, while internally doing all the work of translating PHQL instructions to the most optimal SQL instructions depending on the RDBMS type associated with a model.

To achieve the highest performance possible, we wrote a parser that uses the same technology as SQLite. This technology provides a small in-memory parser with a very low memory footprint that is also thread-safe.

<?php

$intermediate = Phalcon\Mvc\Model\Query\Lang::parsePHQL("SELECT r.* FROM Robots r LIMIT 10");

Methods
