Taken from the Doctrine documentation:

<?php
class User
{
    //...
    /**
     * @ManyToMany(targetEntity="Group")
     * @JoinTable(name="User_Group",
     *      joinColumns={@JoinColumn(name="User_id",
referencedColumnName="id")},
     *      inverseJoinColumns={@JoinColumn(name="Group_id",
referencedColumnName="id")}
     * )
     */
    private $groups;
    //...
}

Not that I'm a fan of it, but it provides a valid usecase. I'm sure
there are more.

Cheers,
Vladislav
