如何在Doctrine 2中为1：1关系指定多个连接条件

Question

Documentation states:

class Cart
{
    // ...

    /**
     * @OneToOne(targetEntity="Customer", inversedBy="cart")
     * @JoinColumn(name="customer_id", referencedColumnName="id")
     */
    private $customer;

    // ...
}

This annotation represents such sql:

JOIN Customer c ON c.id = cart.customer_id

And the issue is that I need to add additional comparison there, like:

JOIN Customer c ON c.id = cart.customer_id AND c.anotherField = <constant>

Any solutions for that?

UPD:

the real additional condition I need for now is <const> BETWEEN c.f1 AND c.f2

Answer 1

you can use the WITH keyword to specify additional join conditions, as you can see in some of the examples.

i think this should get you going:

SELECT l, c FROM location
INNER JOIN Customer c
WITH CURRENT_TIMESTAMP() BETWEEN c.f1 AND c.f2
WHERE CURRENT_TIMESTAMP() BETWEEN l.f1 AND l.f2

i removed the ON clause because i think there's no need to explicitly specify the join's ON fields unless they are not the "standard" ones (id of each entity)

also notice the call to CURRENT_TIMESTAMP() which translates into MySQL's NOW(). check out a list of other pretty useful aggregate functions and expresions here
