# Named Parameter
|
||
|
|
||
|
`perform()`, `fetch*()` und `yield*()`-Methoden nehmen als zweiten Parameter ein assoziatives Array entgegen.
|
||
|
Mit diesem Array werden lassen sich Werte als *Named Parameter* 'binden'.
|
||
|
|
||
|
```php
|
||
|
$sql =
|
||
|
'SELECT a.id, a.nummer, a.name_de
|
||
|
FROM artikel AS a
|
||
|
WHERE a.typ IN (:types)
|
||
|
AND a.nummer LIKE :nummers
|
||
|
LIMIT :start, :length';
|
||
|
|
||
|
$values = [
|
||
|
'types' => ['produkt', 'gebuehr'],
|
||
|
'nummers' => '7000%',
|
||
|
'start' => 0,
|
||
|
'length' => 3,
|
||
|
];
|
||
|
|
||
|
$data = $db->fetchAll($sql, $values);
|
||
|
```
|
||
|
```
