Q: Symfony Doctrine Syntax error or access violation: I am learning symfony and I am trying to apply what is explained in the  "Creating the Database Tables Schema" section of the Doctrine chapter. I run the following command:
php bin/console doctrine:schema:update --force --dump-sql

I get errors:

[Doctrine\DBAL\Exception\SyntaxErrorException]

If I run the dump directly from the mysql> prompt, it creates the table properly
My entity is this one:
<?php

use Doctrine\ORM\Mapping as ORM;

    private $id;

    /**

    private $nom;

    private $descro;

    public function getId()
    {
        return $this->id;
    }

    }

    public function setDescro($descro)
    {
        $this->descro = $descro;

        return $this;
    }

    /**
     * Get descro

    public function getDescro()
    {
        return $this->descro;
    }
}


A: In fact the trouble was due to the fact that I put the entity in a subfolder "Vente" of "AppBundle/Entity". It produced a strange table name Vente/Produit.
Putting it directly in Entity solved the trouble.
