Chapter 9: DQL (Doctrine Query Language) 140
Listing
9-87
->where('u.username LIKE ?', 'A%');
echo $q->getSqlQuery();
The above call to getSql() would output the following SQL query:
SELECT
u.id AS u__id
FROM user u
WHERE u.username LIKE ?
Exists Expressions
Syntax:
Listing
9-88
[NOT ]EXISTS ()
The EXISTS operator returns TRUE if the subquery returns one or more rows and FALSE
otherwise.
The NOT EXISTS operator returns TRUE if the subquery returns 0 rows and FALSE otherwise.
For the next few examples we need to add the ReaderLog model.
Listing
9-89
// models/ReaderLog.php
class ReaderLog extends Doctrine_Record
{
public function setTableDefinition()
{
$this->hasColumn('article_id', 'integer', null, array(
'primary' => true
)
);
}
}
$this->hasColumn('user_id', 'integer', null, array(
'primary' => true
)
);
Here is the same example in YAML format. You can read more about YAML in the YAML
Schema Files (page 195) chapter:
Listing
9-90
---
# schema.yml
# ...
ReaderLog:
columns:
article_id:
type: integer
primary: true
user_id:
