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

    说明

    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.

    参数

    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.

    返回值

    Returns MongoDB\Driver\Cursor on success.

    版本 说明
    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.

    示例

    示例 #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);
    }

    ?>

    以上示例会输出：

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

    示例 #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.
