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

说明

final public MongoDB\Driver\Manager::executeQuery(string $namespace, MongoDB\Driver\Query $query, array $options = array()): 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.

错误／异常

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

更新日志

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.

范例

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);
}

?>

以上例程会输出：

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.
