有没有办法通过Phalcon \ Mvc \ Model \ Criteria进行汇编查询？

Question

I've not found here how we can get builded query by Phalcon\Mvc\Model\Criteria in docs: http://docs.phalconphp.com/en/latest/api/Phalcon_Mvc_Model_Criteria.html

Is it possible?

Answer 1

Phalcon\Mvc\Model\Criteria builds an array of valid parameters for SomeModel::find, or SomeModel::findFirst, this class does not build a real query.

Furthermore, we have Phalcon\Mvc\Query\Builder this class has the ability to build PHQL queries:

<?php

//Get the PHQL to be generated
$phql = $this->modelsManager->createBuilder()
    ->from('Robots')
    ->limit(20);
    ->order('Robots.name')
    ->getPhql();

//Execute the query
$robots = $this->modelsManager->createBuilder()
    ->from('Robots')
    ->limit(20);
    ->order('Robots.name')
    ->getQuery()
    ->execute();
