Приклади

Приклад #1 Mixed write operations

Mixed write operations (i.e. inserts, updates, and deletes) will be sent to the server using a single » bulkWrite command.

<?php

$manager
= new MongoDB\Driver\Manager;

$bulk = new MongoDB\Driver\BulkWriteCommand;

// Delete documents from both collections
$bulk->deleteMany('db.coll_one', []);
$bulk->deleteMany('db.coll_two', []);

// Insert documents into two collections
$bulk->insertOne('db.coll_one', ['_id' => 1]);
$bulk->insertOne('db.coll_two', ['_id' => 2]);
$bulk->insertOne('db.coll_two', ['_id' => 3]);

// Update a document in "coll_one"
$bulk->updateOne('db.coll_one', ['_id' => 1], ['$set' => ['x' => 1]]);

$result = $manager->executeBulkWriteCommand($bulk);

printf("Inserted %d document(s)\n", $result->getInsertedCount());
printf("Updated %d document(s)\n", $result->getModifiedCount());

?>

Поданий вище приклад виведе:

Inserted 3 document(s)
Updated  1 document(s)

Приклад #2 Ordered write operations causing an error

<?php

$manager
= new MongoDB\Driver\Manager;

$bulk = new MongoDB\Driver\BulkWriteCommand;

$bulk->deleteMany('db.coll', []);
$bulk->insertOne('db.coll', ['_id' => 1]);
$bulk->insertOne('db.coll', ['_id' => 2]);
$bulk->insertOne('db.coll', ['_id' => 1]);
$bulk->insertOne('db.coll', ['_id' => 3]);

try {
$result = $manager->executeBulkWriteCommand($bulk);
} catch (
MongoDB\Driver\Exception\BulkWriteCommandException $e) {
$result = $e->getPartialResult();

var_dump($e->getWriteErrors());
}

printf("Inserted %d document(s)\n", $result->getInsertedCount());

?>

Поданий вище приклад виведе щось схоже на:

array(1) {
  [3]=>
  object(MongoDB\Driver\WriteError)#5 (4) {
    ["message"]=>
    string(78) "E11000 duplicate key error collection: db.coll index: _id_ dup key: { _id: 1 }"
    ["code"]=>
    int(11000)
    ["index"]=>
    int(3)
    ["info"]=>
    object(stdClass)#6 (0) {
    }
  }
}
Inserted 2 document(s)
