Hello,

In the context of a large project, I generated multiple entities from a MS SQL database.
I notice that all fields nvarchar(MAX) were translated in annotation attribute length=0 like this:

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=0, nullable=true)
     */
    protected $name;

Shouldn't be better to remove the length limit in this case ?

@ajira86 a removed length would result in a length=255 by default. Also, seems like a schema introspection issue. Can this be isolated into the DBAL code that causes it, and then reported there in more detail?

Thank you for your reply, I was not excepting this default value.

How can I get this kind of report ?

FYI: I'm using Symfony and the module leaseweb/doctrine-pdo-dblib as DBAL driver for the use of FreeTDS

@ajira86 you'd need to debug it and figure out what the DatabaseDriver does, then figure out if the MAX is cast to 0 by the DBAL or by the driver itself.
