# MongoDB\Driver\Manager::executeBulkWriteCommand

(mongodb >=2.1.0)

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`

  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.

### 返回值

Returns MongoDB\Driver\BulkWriteCommandResult on success.

### 错误／异常

- Throws MongoDB\Driver\Exception\InvalidArgumentException if `bulk` does not contain any write operations.
- Throws MongoDB\Driver\Exception\InvalidArgumentException if `bulk` has already been executed. MongoDB\Driver\BulkWriteCommand objects may not be executed multiple times.
- Throws MongoDB\Driver\Exception\InvalidArgumentException if the `"session"` option is used in combination with an unacknowledged write concern.
- Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
- Throws MongoDB\Driver\Exception\ConnectionException if connection to the server fails (for reasons other than authentication).
- Throws MongoDB\Driver\Exception\AuthenticationException if authentication is needed and fails.
- Throws MongoDB\Driver\Exception\BulkWriteCommandException on any write failure (e.g. command failure, write or write concern error)
- Throws MongoDB\Driver\Exception\RuntimeException on other errors.

### 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)
