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

    Descrição

    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.

    Parâmetros

    namespace (string)

    Um namespace totalmente qualificado (por exemplo, "nomeDoBancoDados.nomeDaColecao").

    query (MongoDB\Driver\Query)

    A consulta a ser executada.

    options

    options
    Option Type Description
    readPreference MongoDB\Driver\ReadPreference

    Versão Descrição
    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.

    Exemplos

    Exemplo #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);
    }

    ?>

    O exemplo acima produzirá:

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

    Exemplo #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.
