Jira issue originally created by user breiti:

Given following 2 entities:

<?php
class Role {
    /****
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="UUID")
     * @ORM\Column(name="id", type="guid", nullable=false, unique=true, length=36, options={"fixed"=true})
     */
    protected $id;

    /****
     * @ORM\ManyToMany(targetEntity="User", mappedBy="roleList")
     */
    private $userList;
}
<?php
class User {
    /****
     * @ORM\Column(name="id", type="guid", nullable=false, unique=true, length=36, options={"fixed"=true})
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="UUID")
     */
    protected $id;

    /***     **
     * @ORM\ManyToMany(targetEntity="Role", inversedBy="userList")
     * @ORM\JoinTable(name="user_role")
    protected $roleList;
}

It should create a table "user_role" with 2 columns which are CHAR(36).

But it ignores the Column-Attributes and creates a table "user_role" with 2 CHAR(255) columns.

This has various downsides:

  • It's unusable when using MyISAM, because of limited index size. (CREATE TABLE fails, see DBAL-423) ** If using GUID-Type (see DBAL-423 with the changes from the linked ull request) and specify "length=36" and "fixed=true" on the Column-Annotation, no changes for the entity-tables itself are generated when running orm:schema-tool:update. However, there are still changes for the many-to-many-table generated (because internal "fixed" is false and length is unset) which represent the current state of the columns. These changes are always* generated.
