Doctrine 2 with multiple indexes

Question

I am developing using zend framework and doctrine2.1.

I have generated entities from database.

But the problem is: Doctrine doesn\'t recognize my indexes. They

Answer 1

Here is an example:

/**
 * @Entity
 * @Table(name="serial_number",indexes={
 *  @index(name="product_idx", columns={"product_id"}),
 * })
 */
class SerialNumber { // Entity Class

    /**
     * @var int
     * 
     * @Id
     * @GeneratedValue
     * @Column(type="integer")
     */

    protected $id;

    /**
     * @Column(name="created_at", type="datetime")
     * @var \DateTime
     * */
    protected $created;

    /**
     * @Column(name="updated_at", type="datetime")
     * @var \DateTime
     * */
    protected $updated;

    /**
     * @Column(name="product_id", type="integer")
     */
    protected $productID;

}

Answer 2

I would say you can insert multiple indexes in the indexes property (but I haven't had the time to test it):

indexes={
@ORM\Index(name="index_name", columns={"database_column1","database_column2"}),
@ORM\Index(name="index_name2", columns={"database_column1"}),
@ORM\Index(name="index_name3", columns={"database_column2"})
}

Hope this helps you
