    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.

    Default values for the "readPreference" option and Query's "readConcern" option will be inferred from an active transaction (indicated by the "session" option), followed by the connection URI.

    Parameters

    namespace (string)

    A fully qualified namespace (e.g. "databaseName.collectionName").

    query (MongoDB\Driver\Query)

    The query to execute.

    options

    options
    Option Type Description
    readPreference MongoDB\Driver\ReadPreference

    A read preference to use for selecting a server for the operation.

    session MongoDB\Driver\Session

    A session to associate with the operation.

    Return Values

    Returns MongoDB\Driver\Cursor on success.

    Errors/Exceptions

    Changelog

    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.

    Examples

    Example #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);
    }

    ?>

    The above example will output:

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

    Example #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.
