MongoDB\Driver\Manager::executeBulkWriteCommand — Execute write operations using the bulkWrite command
$bulk, ?array $options = null): MongoDB\Driver\BulkWriteCommandResultExecutes 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.
bulk (MongoDB\Driver\BulkWriteCommand)The write(s) to execute.
options
| Option | Type | Description |
|---|---|---|
| session | MongoDB\Driver\Session |
Eine Session, die mit dem Vorgang verknüpft werden soll. |
| writeConcern | MongoDB\Driver\WriteConcern |
Ein Schreibanliegen (Write Concern), das auf den Vorgang angewendet werden soll. |
Returns MongoDB\Driver\BulkWriteCommandResult on success.
bulk does not contain any write operations.bulk has already been executed. MongoDB\Driver\BulkWriteCommand objects may not be executed multiple times."session" in Kombination mit einer unbestätigten Schreibanweisung verwendet wird.Beispiel #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());
?>Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Inserted 3 document(s) Updated 1 document(s)
Beispiel #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());
?>Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
array(1) {
[3]=>
object(MongoDB\Driver\WriteError)#5 (4) {
["message"]=>
