(mongodb >=1.0.0)

MongoDB\Driver\Manager::executeBulkWrite — Execute one or more write operations

说明

final public MongoDB\Driver\Manager::executeBulkWrite ( string $namespace , MongoDB\Driver\BulkWrite $bulk , array $options = array() ) : MongoDB\Driver\WriteResult

Executes one or more write operations on the primary server.

A MongoDB\Driver\BulkWrite can be constructed with one or more write operations of varying types (e.g. updates, deletes, and inserts). The driver will attempt to send operations of the same type to the server in as few requests as possible to optimize round trips.

参数

namespace (string)

A fully qualified namespace (e.g. "databaseName.collectionName").

bulk (MongoDB\Driver\BulkWrite)

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\WriteResult on success.

错误／异常

更新日志

版本 说明
PECL mongodb 1.4.4 MongoDB\Driver\Exception\InvalidArgumentException will be thrown if the "session" option is used in combination with an unacknowledged write concern.
PECL mongodb 1.4.0 The third parameter is now an options array. For backwards compatibility, this paramater will still accept a MongoDB\Driver\WriteConcern object.
PECL mongodb 1.3.0 MongoDB\Driver\Exception\InvalidArgumentException is now thrown if bulk does not contain any write operations. Previously, a MongoDB\Driver\Exception\BulkWriteException was thrown.

范例

Example #1 MongoDB\Driver\Manager::executeBulkWrite() example

<?php

$bulk = new MongoDB\Driver\BulkWrite();

$bulk->insert(['_id' => 1, 'x' => 1]);
$bulk->insert(['_id' => 2, 'x' => 2]);

$bulk->update(['x' => 2], ['$set' => ['x' => 1]], ['multi' => false, 'upsert' => false]);
$bulk->update(['x' => 3], ['$set' => ['x' => 3]], ['multi' => false, 'upsert' => true]);
$bulk->update(['_id' => 3], ['$set' => ['x' => 3]], ['multi' => false, 'upsert' => true]);

$bulk->insert(['_id' => 4, 'x' => 2]);

$bulk->delete(['x' => 1], ['limit' => 1]);

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY, 100);
$result = $manager->executeBulkWrite('db.collection', $bulk, $writeConcern);

printf("Inserted %d document(s)\n", $result->getInsertedCount());
printf("Matched  %d document(s)\n", $result->getMatchedCount());
printf("Updated  %d document(s)\n", $result->getModifiedCount());
printf("Upserted %d document(s)\n", $result->getUpsertedCount());
printf("Deleted  %d document(s)\n", $result->getDeletedCount());

foreach ($result->getUpsertedIds() as $index => $id) {
    printf('upsertedId[%d]: ', $index);
    var_dump($id);
}

/* If the WriteConcern could not be fulfilled */
if ($writeConcernError = $result->getWriteConcernError()) {
    printf("%s (%d): %s\n", $writeConcernError->getMessage(), $writeConcernError->getCode(), var_export($writeConcernError->getInfo(), true));
}

/* If a write could not happen at all */
foreach ($result->getWriteErrors() as $writeError) {
    printf("Operation#%d: %s (%d)\n", $writeError->getIndex(), $writeError->getMessage(), $writeError->getCode());
}
?>

以上例程的输出类似于：

Inserted 3 document(s)
Matched  1 document(s)
Updated  1 document(s)
Upserted 2 document(s)
Deleted  1 document(s)
upsertedId[3]: object(MongoDB\BSON\ObjectId)#5 (1) {
  ["oid"]=>
  string(24) "54d3adc3ce7a792f4d703756"
}
upsertedId[4]: int(3)

If you're trying to figure out how to insert just one object and NOT an array resulting in a bunch of unwanted [0]s in your schema, I'm sorry I cannot help you. I've scoured the SERPs and since MongoDB\Driver\BulkWrite only takes an array it appears there is literally no way to "insertOne" in PHP7, nor a way to pass JUST an object and NOT an array, which may mean you must use a different language or revert to shell commands :-\.

There are several articles where people, apparently mistakenly, refer to "MongoDB\Driver\Client" but neither that nor "MongoDB\Driver\Collections" appear to exist at all. I'm devastated, but if this forces me to downgrade to PHP5 on a brand new project I'll just need to move to a more modern language. :-(

After several hours of this torture I'm now going to spend another hour trying to figure out if I can compose an update query that will collapse the unnecessary array that is being stuck where an object (document) should be. Ug. I realize people using MongoDB have mostly fled PHP, but abandoning the few & loyal among us is really very sad as has been attested to by the unresolved stackoverflow laments that have been going on for years.
