说明

final public MongoDB\Driver\Cursor MongoDB\Driver\Manager::executeQuery ( string $namespace , MongoDB\Driver\Query $query [, MongoDB\Driver\ReadPreference $readPreference ] )

Executes query on a server. If readPreference is provided, it will be used for server selection; otherwise, the default read preference will be used.

参数

namespace (string)

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

query (MongoDB\Driver\Query)

The MongoDB\Driver\Query to execute.

readPreference (MongoDB\Driver\ReadPreference)

Optionally, a MongoDB\Driver\ReadPreference to select the server for this operation. If none is given, the read preference from the MongoDB Connection URI will be used.

返回值

Returns MongoDB\Driver\Cursor on success.

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);
}

?>

以上例程会输出：

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