    MongoDB\Driver\BulkWrite::__construct — Create a new BulkWrite

    Beschreibung

    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().

    Parameter-Liste

    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

    Die Zuordnung von Parameternamen und -werten. Die Werte müssen Konstanten oder geschlossene Ausdrücke sein, die nicht auf Dokumentfelder verweisen. Auf die Parameter kann dann als Variablen im Kontext eines aggregierten Ausdrucks zugegriffen werden (z. B. $$var).

    Diese Option ist ab MongoDB 5.0 verfügbar. Wenn sie bei einer älteren Serverversion angegeben wird, kommt es bei der Ausführung zu einer Exception.

    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

    Beispiele

    Beispiel #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());

    ?>

    Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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