    MongoDB\Driver\Manager::executeQuery — Execute a database query

    Description

    final public MongoDB\Driver\Manager::executeQuery(string $namespace, MongoDB\Driver\Query $query, array|MongoDB\Driver\ReadPreference|null $options = null): MongoDB\Driver\Cursor

    Selects a server according to the "readPreference" option and executes the query on that server. By default, the read preference from the MongoDB Connection URI will be used.

    Liste de paramètres

    namespace (string)

    Un espace de noms totalement qualifié (e.g. "databaseName.collectionName")

    query (MongoDB\Driver\Query)

    La requête à exécuter.

    options

    options
    Option Type Description
    readPreference MongoDB\Driver\ReadPreference

    Une préférence de lecture à utiliser pour sélectionner un serveur pour l'opération.

    session MongoDB\Driver\Session

    Une session à associer à l'opération.

    Valeurs de retour

    Retourne un MongoDB\Driver\Cursor en cas de succès.

    Erreurs / Exceptions

    • Lance une exception MongoDB\Driver\AuthenticationException si une identification est nécessaire mais qu'elle échoue
    • Lance une exception MongoDB\Driver\ConnectionException si la connexion au serveur échoue pour une autre raison qu'en raison d'un problème d'identification
    • Throws MongoDB\Driver\Exception\RuntimeException on other errors (e.g. invalid query operators).

    Historique

    Version Description
    PECL mongodb 1.4.0 The third parameter is now an options array. For backwards compatibility, this paramater will still accept a MongoDB\Driver\ReadPreference object.

    Exemples

    Exemple #1 MongoDB\Driver\Manager::executeQuery() example

    <?php

    $manager     = new MongoDB\Driver\Manager("mongodb://localhost:27017");

    $bulk = new MongoDB\Driver\BulkWrite;
    $bulk->insert(['x' => 1]);
    $bulk->insert(['x' => 2]);
    $bulk->insert(['x' => 3]);
    $manager->executeBulkWrite('db.collection', $bulk);

    $filter = ['x' => ['$gt' => 1]];
    $options = [
    'projection' => ['_id' => 0],
    'sort' => ['x' => -1],
    ];

    $query = new MongoDB\Driver\Query($filter, $options);
    $cursor = $manager->executeQuery('db.collection', $query);

    foreach (    $cursor as $document) {
    var_dump($document);
    }

    ?>

    L'exemple ci-dessus va afficher :

    object(stdClass)#6 (1) {
  ["x"]=>
  int(3)
}
object(stdClass)#7 (1) {
  ["x"]=>
  int(2)
}

    Exemple #2 Limiting execution time for a query

    The "maxTimeMS" MongoDB\Driver\Query option may be used to limit the execution time of a query. Note that this time limit is enforced on the server side and does not take network latency into account. See » Terminate Running Operations in the MongoDB manual for more information.

    <?php

    $manager     = new MongoDB\Driver\Manager('mongodb://localhost:27017');

    $filter = ['x' => ['$gt' => 1]];
    $options = [
    'maxTimeMS' => 1000,
    ];

    $query = new MongoDB\Driver\Query($filter, $options);
    $cursor = $manager->executeQuery('db.collection', $query);

    foreach (    $cursor as $document) {
    var_dump($document);
    }

    ?>

    If the query fails to complete after one second of execution time on the server, a MongoDB\Driver\Exception\ExecutionTimeoutException will be thrown.
