无法在 Symfony 4 中使用 Doctrine2 DBAL\\Connection 插入数据

Question

I am trying to insert some data in a MySQL table with Doctrine2 DBAL\\Connection ( for tables that I don't want to be mapped ), with this code:

<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;
use Doctrine\DBAL\Connection;

class UtilsController extends AbstractController
{
    /**
     * @Route("/utils/fixer", name="utils_fixer")
     */
    public function dataFixer(Connection $conn)
    {
        $sql = "INSERT INTO test(id, username) VALUES (':id', ':name')";

        $id = 456;
        $name = 'blabla';

        $res = $conn->executeUpdate($sql, ['id' => $id, 'name' => $name]);

        return $this->render('utils/index.html.twig', ['res' => $res]);
    }
}

This is what my table looks like:

This is giving me: "SQLSTATE[HY000]: General error: 1366 Incorrect integer value: ':id' for column 'id' at row 1".

The Id field has no auto increment , it's just a test table.

SELECT statement is returning data OK.

Value binding doesn't seem to work ??

I used this Doctrine documentation .

Answer 1

The placeholders shouldn't be quoted.

At least this gives a usage example of the executeUpdate() method.

public function dataFixer(Connection $conn)
{
    $sql = "INSERT INTO test(id, username) VALUES (:id, :name)";

    $id = 456;
    $name = 'blabla';

    $res = $conn->executeUpdate($sql, ['id' => $id, 'name' => $name]);

    return $this->render('utils/index.html.twig', ['res' => $res]);
}

Answer 2

如果该值是自动递增的，则不应插入 $id 的值 - 正如我认为的那样。
