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 |
A session to associate with the operation. |
| writeConcern | MongoDB\Driver\WriteConcern |
A write concern to apply to the operation. |
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" option is used in combination with an unacknowledged write concern.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)
