The above call to getSql() would output the following SQL query:
SELECT
u.id AS u__id
FROM user u
WHERE u.type = 'admin'
Predefined reserved literals are case insensitive, although its a good standard to write them
in uppercase.
Input parameters
Here are some examples of using positional parameters:
Single positional parameter:
Listing
9-70
// test.php
// ...
$q = Doctrine_Query::create()
->select('u.id')
->from('User u')
->where('u.username = ?', array('Arnold'));
echo $q->getSqlQuery();
When the passed parameter for a positional parameter contains only one value you can
simply pass a single scalar value instead of an array containing one value.
The above call to getSql() would output the following SQL query:
Listing
9-71
SELECT
u.id AS u__id
FROM user u
WHERE u.username = ?
Multiple positional parameters:
Listing
9-72
// test.php
// ...
$q = Doctrine_Query::create()
->from('User u')
->where('u.id > ? AND u.username LIKE ?', array(50, 'A%'));
echo $q->getSqlQuery();
The above call to getSql() would output the following SQL query:
Listing
9-73
SELECT
u.id AS u__id
FROM user u
WHERE (u.id > ?
AND u.username LIKE ?)
Here are some examples of using named parameters:
