Listing

// test.php
Listing

// ...
$q = Doctrine_Query::create()
->select('u.username')
->from('User u')
->leftJoin('u.Email e')
->orderBy('e.address DESC, u.id ASC');
echo $q->getSqlQuery();
The above call to getSql() would output the following SQL query:
SELECT
u.id AS u__id,
u.username AS u__username
FROM user u
LEFT JOIN email e ON u.id = e.user_id
ORDER BY e.address DESC,
u.id ASC
Sorting by an aggregate value
In the following example we fetch all users and sort those users by the number of
phonenumbers they have.
Listing
9-135
// test.php
Listing
9-136
// ...
$q = Doctrine_Query::create()
->select('u.username, COUNT(p.id) count')
->from('User u')
->innerJoin('u.Phonenumbers p')
->orderby('count');
echo $q->getSqlQuery();
The above call to getSql() would output the following SQL query:
SELECT
u.id AS u__id,
u.username AS u__username,
COUNT(p.id) AS p__0
FROM user u
INNER JOIN phonenumber p ON u.id = p.user_id
ORDER BY p__0
Using random order
In the following example we use random in the ORDER BY clause in order to fetch random
post.
Listing
9-137
// test.php
// ...
$q = Doctrine_Query::create()
->select('t.id, RANDOM() AS rand')
