Doctrine QueryBuilder undefined method getQuery() - php

Question

When I execute the method getMachineSettings I get an error:
Fatal error: Uncaught Error: Call to undefined method Doctrine\DBAL\Query\QueryBuilder::getQuery()
$data is an associative array:
$data['param'] = 'ip';
$data['value'] = '192.168.240.10';
If I replace getQuery()->getResult() with execute(), $result contains the query:
SELECT * FROM machine WHERE ip = ?
public function __construct()
{
try
{
$dbconf = parse_ini_file('.htLogin.ini');
$config = new \Doctrine\DBAL\Configuration();
$connectionParams = array
(
'dbname' => $dbconf['infoDb'],
'user' => $dbconf['infoLogin'],
'password' => $dbconf['infoPw'],
'host' => $dbconf['infoHost'],
'driver' => 'pdo_mysql',
'charset' => 'utf8',
'driverOptions' => array
(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8'
)
);
$this->mysql = \Doctrine\DBAL\DriverManager::getConnection($connectionParams, $config);
}
catch(PDOException $e)
{
echo $e -> getMessage();
}
public function getMachineSettings($data)
{
$qb = $this->mysql->createQueryBuilder();
$qb->SELECT('*')
->FROM('`machine`')
->WHERE($data['param'] . ' = :value');
$qb->setParameters(
array
(
':value' => $data['value']
)
);
$results = $qb->getQuery()->getResult();
var_dump($result);
return $result;
}
Do you have any idea why the method getQuery() is not recognised?

Answer 1

Just do
$results = $qb->execute()->fetchAll();
Ignore the below - it assumes that your using the Doctrine ORM, which your not
The issue your having is that the QueryBuilder object your working with isn't the Doctrine ORM QueryBuilder - its the DBAL QueryBuilder.
You need to use the createQueryBuilder function from the EntityManager.
/** #var Doctrine\ORM\QueryBuilder $qb */
$qb = $this->entityManager->createQueryBuilder();
Then you can use the select / from etc methods and to get the result of the query you can run
$qb->getQuery()->getResult()
If I was to rewrite your function I would write it like this
public function getMachineSettings(string $field, string $value)
{
$qb = $this->entityManager->createQueryBuilder();
$qb->select('m')
->from('machine')
->where($field.' = :value');
$qb->setParameter('value', $value);
$results = $qb->getQuery()->getResult();
var_dump($result);
return $result;
}
Then you know that the function requires 2 parameters to function, passing an array doesn't let you immediately see what the function requires
