(mongodb >=1.0.0)

MongoDB\Driver\Manager::executeQueryExecute 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.

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.

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

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.
