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

    Descripción

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

    query (MongoDB\Driver\Query)

    La consulta a ejecutar.

    Versión Descripción
    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.

    Ejemplos

    Ejemplo #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);
    }

    ?>

    El resultado del ejemplo sería:

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

    Ejemplo #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.
