doctrine2/manual/docs/Working with objects - Component overview - RawSql - Adding components.php

The following example represents a bit harder case where we select all entities and their associated phonenumbers using a left join. Again we
wrap all the columns in curly brackets but we also specify what tables associate to which components.

 

First we specify that table entity maps to record class 'Entity'



Then we specify that table phonenumber maps to Entity.Phonenumber (meaning phonenumber associated with an entity)

<code type="php">
$query = new Doctrine_RawSql($conn);

$query->parseQuery("SELECT {entity.*}, {phonenumber.*} 
                   FROM entity 
                   LEFT JOIN phonenumber 
                   ON phonenumber.entity_id = entity.id");

$query->addComponent("entity", "Entity");
$query->addComponent("phonenumber", "Entity.Phonenumber");

$entities = $query->execute();
