The FROM clause indicates the component or components from which to retrieve records.
|
|
If you name more than one component, you are performing a join.
|
|
For each table specified, you can optionally specify an alias. Doctrine_Query offers easy to use
|
|
methods such as from(), addFrom(), leftJoin() and innerJoin() for managing the FROM part of your DQL query.
|
|
|
|
|
|
|
|
<code type="php">
|
|
// find all users
|
|
\$q = new Doctrine_Query();
|
|
|
|
\$coll = \$q->from('User')->execute();
|
|
|
|
// find all users with only their names (and primary keys) fetched
|
|
|
|
\$coll = \$q->select('u.name')->('User u');
|
|
?></code>

The following example shows how to use leftJoin and innerJoin methods:
|
|
|
|
|
|
|
|
<code type="php">
|
|
// find all groups
|
|
|
|
$coll = $q->from("FROM Group");
|
|
|
|
// find all users and user emails
|
|
|
|
$coll = $q->from("FROM User u LEFT JOIN u.Email e");
|
|
|
|
// find all users and user emails with only user name and
|
|
// age + email address loaded
|
|
|
|
$coll = $q->select('u.name, u.age, e.address')
|
|
->from('FROM User u')
|
|
->leftJoin('u.Email e')
|
|
->execute();
|
|
|
|
// find all users, user email and user phonenumbers
|
|
|
|
$coll = $q->from('FROM User u')
|
|
->innerJoin('u.Email e')
|
|
->innerJoin('u.Phonenumber p')
|
|
->execute();
|
|
