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.

Parameter-Liste

namespace

A fully qualified namespace (databaseName.collectionName)

query (MongoDB\Driver\Query)

The query to execute.

options

options
Option Type Description
readPreference MongoDB\Driver\ReadPreference

session MongoDB\Driver\Session

A session to associate with the operation.

Rückgabewerte

Returns MongoDB\Driver\Cursor on success.

Fehler/Exceptions

  • Throws MongoDB\Driver\AuthenticationException if authentication is needed and fails
  • Throws MongoDB\Driver\ConnectionException if connection to the server fails for other then authentication reasons
  • Throws MongoDB\Driver\Exception\RuntimeException on other errors (e.g. invalid query operators).

Changelog

Version Beschreibung
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.

Beispiele

Beispiel #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);
}

?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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

Beispiel #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.
