Question

我遵循《学说》中的分页示例，但遇到致命错误：

PHP Fatal error:  Uncaught Doctrine\ORM\Query\QueryException: SELECT * FROM Model\Report r in /usr/share/nginx/html/td/vendor/doctrine/orm/lib/Doctrine/ORM/Query/QueryException.php:43
Stack trace:

这是教义的默认示例 https://www.doctrine-project.org/projects/doctrine-orm/en/2.6/tutorials/pagination.html

这是我的代码：

<?php
use Doctrine\ORM\Tools\Pagination\Paginator;
require "bootstrap.php";

$dql = 'SELECT * FROM reports';

$max = isset($args[1])?$args[1]:5;

$query = $entityManager->createQuery($dql)->setFirstResult(0)->setMaxResults($max);

$paginator = new Paginator($query, $fetchJoinCollection = false);

$c = count($paginator);

foreach($paginator as $report){
    echo $report->getName() . "\n";
}

Answer 1

dql 选择中没有通配符* 。

更改

$dql = 'SELECT * FROM reports';

到

$dql = 'SELECT r FROM Model\Report r';

参考

原则DQL在查询生成器上引发致命错误
