[Bug][MySQL] Invalid query when creating a Json column with deafult value

[valentimarco]

Bug Report

Q	A
BC Break	no
Version	2.15

Summary

I have a [email protected] and i cannot set a JSON default value on one column.

Current behavior

From the entity below, i cannot setup correctly the default value of the column when is declare as json. Further investigation discover that the orm does an invalid query to mysql:

• correct query: CREATE TABLE setting (id INT AUTO_INCREMENT NOT NULL, settings JSON DEFAULT ('{}') NOT NULL, PRIMARY KEY(id))
• ORM generated query: CREATE TABLE setting (id INT AUTO_INCREMENT NOT NULL, settings JSON DEFAULT '(''{}'')' NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE = InnoDB

How to reproduce

setting.php

#[ORM\Entity(repositoryClass: SettingRepository::class)]
class Setting
{
    #[ORM\Id]
    #[ORM\GeneratedValue]
    #[ORM\Column]
    private ?int $id = null;

    /**
     * @var array<string, mixed>
     */
    #[ORM\Column(type: 'json', options: ['default' => "('{}')"])]
    private array $settings = [];

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

    /**
     * @return array<string, mixed>
     */
    public function getSettings(): array
    {
        return $this->settings;
    }

    /**
     * @param array<string, mixed> $settings
     */
    public function setSettings(array $settings): self
    {
        $this->settings = $settings;
        return $this;
    }
}

Pipeline to inizialize the database

        php bin/console doctrine:database:create --if-not-exists --env=${env}
	php bin/console doctrine:schema:drop --force --env=${env}
	php bin/console doctrine:schema:create --env=${env}
	php bin/console doctrine:fixtures:load --env=${env} -q

Expected behavior

I aspect to have the column of type json with the default json. I can resolve the problem by using migration but is not scalable...
