How to solve schema update error with doctrine? - database

Question

I'm having an issue on a pretty simple application made with Symfony 4.3.4
I just updated an entity and I'm trying to update my database with "doctrine:schema:update --force", but I have here an issue : An exception occurred while executing 'ALTER TABLE lead ADD content LONGTEXT DEFAULT NULL'
Second message : Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'lead ADD content LONGTEXT DEFAULT NULL' at line 1
I tried to change the name of the "content" attribute (it's the one I added), but this did not work. Do someone know why this is happening ?
Here is my Lead entity :
<?php
namespace App\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity(repositoryClass="App\Repository\LeadRepository")
*/
class Lead
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="datetime")
*/
private $createdAt;
/**
* #ORM\Column(type="boolean")
*/
private $isAuth = false;
/**
* #ORM\ManyToOne(targetEntity="App\Entity\Formation", inversedBy="leads")
* #ORM\JoinColumn(nullable=false)
*/
private $formation;
/**
* #ORM\Column(type="text", nullable=true)
*/
private $content;
public function __construct()
{
$this->createdAt = new \DateTime();
}
public function getId(): ?int
{
return $this->id;
}
public function getCreatedAt(): ?\DateTimeInterface
{
return $this->createdAt;
}
public function setCreatedAt(\DateTimeInterface $createdAt): self
{
$this->createdAt = $createdAt;
return $this;
}
public function getIsAuth(): ?bool
{
return $this->isAuth;
}
public function setIsAuth(bool $isAuth): self
{
$this->isAuth = $isAuth;
return $this;
}
public function getFormation(): ?Formation
{
return $this->formation;
}
public function setFormation(?Formation $formation): self
{
$this->formation = $formation;
return $this;
}
public function getContent(): ?string
{
return $this->content;
}
public function setContent(?string $content): self
{
$this->content = $content;
return $this;
}
}

"lead" seems to be a reserved keyword for MySQL, so you need to escape it with backticks as follows:
/**
* #ORM\Entity(repositoryClass="App\Repository\LeadRepository")
* #ORM\Table(name="`lead`")
*/
You need to do this for other common keywords used as field names such as "order" and "sort" too.
