Descrição

public MongoDB\Driver\BulkWrite::__construct(?array $options = null)

Constructs a new MongoDB\Driver\BulkWrite, which is a mutable object to which one or more write operations may be added. The write(s) may then be executed with MongoDB\Driver\Manager::executeBulkWrite().

Parâmetros

options (array)

options
Option Type Description Default
bypassDocumentValidation bool

If true, allows insert and update operations to circumvent document level validation.

This option is available in MongoDB 3.2+ and is ignored for older server versions, which do not support document level validation.

false
comment mixed

An arbitrary comment to help trace the operation through the database profiler, currentOp output, and logs.

This option is available in MongoDB 4.4+ and will result in an exception at execution time if specified for an older server version.

let array|object

Mapa de nomes e valores de parâmetros. Os valores devem ser expressões constantes ou fechadas que não fazem referência a campos do documento. Os parâmetros podem então ser acessados como variáveis em um contexto de expressão agregada (por exemplo, $$var).

Esta opção está disponível no MongoDB 5.0+ e resultará em uma exceção em tempo de execução se for especificada para uma versão de servidor mais antiga.

ordered bool Ordered operations (true) are executed serially on the MongoDB server, while unordered operations (false) are sent to the server in an arbitrary order and may be executed in parallel. true

Exemplos

Exemplo #1 MongoDB\Driver\BulkWrite::__construct() example

<?php

$bulk
= new MongoDB\Driver\BulkWrite(['ordered' => true]);
$bulk->delete([]);
$bulk->insert(['_id' => 1, 'x' => 1]);
$bulk->insert(['_id' => 2, 'x' => 2]);
$bulk->update(
[
'x' => 2],
[
'$set' => ['x' => 1]],
[
'limit' => 1, 'upsert' => false]
);
$bulk->delete(['x' => 1], ['limit' => 1]);
$bulk->update(
[
'_id' => 3],
[
'$set' => ['x' => 3]],
[
'limit' => 1, 'upsert' => true]
);

$manager = new MongoDB\Driver\Manager('mongodb://localhost:27017');
$writeConcern = new MongoDB\Driver\WriteConcern(1);

try {
$result = $manager->executeBulkWrite('db.collection', $bulk, $writeConcern);
} catch (
MongoDB\Driver\Exception\BulkWriteException $e) {
$result = $e->getWriteResult();

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

// Check if any write operations did not complete at all
foreach ($result->getWriteErrors() as $writeError) {
printf("Operation#%d: %s (%d)\n",
$writeError->getIndex(),
$writeError->getMessage(),
$writeError->getCode()
);
}
} catch (
MongoDB\Driver\Exception\Exception $e) {
printf("Other error: %s\n", $e->getMessage());
exit;
}

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

?>

O exemplo acima produzirá:

Inserted 2 document(s)
Updated  1 document(s)
Upserted 1 document(s)
Deleted  1 document(s)
