MongoDB\Driver\Manager::executeBulkWriteCommand — Execute write operations using the bulkWrite command

说明

final public MongoDB\Driver\Manager::executeBulkWriteCommand(MongoDB\Driver\BulkWriteCommand $bulk, ?array $options = null): MongoDB\Driver\BulkWriteCommandResult

Executes one or more write operations on the primary server using the » bulkWrite command introduced in MongoDB 8.0.

A MongoDB\Driver\BulkWriteCommand can be constructed with one or more write operations of varying types (e.g. inserts, updates, and deletes). Each write operation may target a different collection.

The default value for the "writeConcern" option will be inferred from an active transaction (indicated by the "session" option), followed by the connection URI.

参数

bulk (MongoDB\Driver\BulkWriteCommand)

The write(s) to execute.

options

Option Type Description
session MongoDB\Driver\Session

错误／异常

示例

示例 #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());

?>

以上示例会输出：

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

示例 #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());

?>

以上示例的输出类似于：

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)
