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)Écriture(s) à exécuter.
options
| Option | Type | Description |
|---|---|---|
| session | MongoDB\Driver\Session |
Une session à associer à l'opération. |
| writeConcern | MongoDB\Driver\WriteConcern |
Une préoccupation d'écriture à appliquer à l'opération. |
Retourne un MongoDB\Driver\BulkWriteCommandResult en cas de succès.
bulk does not contain any write operations.bulk has already been executed. MongoDB\Driver\BulkWriteCommand objects may not be executed multiple times."session" est utilisée conjointement avec une préoccupation d'écriture non reconnu.Exemple #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());
?>L'exemple ci-dessus va afficher :
Inserted 3 document(s) Updated 1 document(s)
Exemple #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());
?>Résultat de l'exemple ci-dessus est similaire à :
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 }"
