Jira issue originally created by user ablock:

A class A has a bidirectional onetomany assocation with a class B. The primary key for A is called "a_id" and is defined like this:

   /****
     * @Id @Column(name="a_id", type="integer")
     * @GeneratedValue(strategy="AUTO")
     */
    private $id;

issuing the command ./doctrine run-dql --dql="select a from Domain3\A a join a.b b where b.id = 1" gives the following error:

PHP Notice: Undefined index: id in /home/ablock/doctrine/lib/Doctrine/ORM/Query/SqlWalker.php on line 657

If I change the declaration to

/****
     * @Id @Column(type="integer")
     * @GeneratedValue(strategy="AUTO")
     */
    private $id;

It works

Comment created by romanb:

This may simply be because you change the id column name but you dont change the association mapping appropriately (@JoinColumn(name..., referencedColumnName...). You probably still use "id" there.

Comment created by romanb:

You probably simply forgot to adjust the @JoinColumn to reference the new column name a_id instead of id.
If you still have issues or something is unclear, please report back.
