MongoDB\Driver\Server::executeWriteCommand

(mongodb >=1.4.0)

MongoDB\Driver\Server::executeWriteCommandExecute a database command that writes on this server

Beschreibung

final public MongoDB\Driver\Server::executeWriteCommand(string $db, MongoDB\Driver\Command $command, ?array $options = null): MongoDB\Driver\Cursor

Executes the command on this server.

This method will apply logic that is specific to commands that write (e.g. » drop) and take the MongoDB server version into account. The "writeConcern" option will default to the corresponding value from the MongoDB Connection URI.

Hinweis: This method is not intended to be used to execute » insert, » update, or » delete commands. Users are encouraged to use MongoDB\Driver\Server::executeBulkWrite() for those commands.

Parameter-Liste

db (string)

The name of the database on which to execute the command.

command (MongoDB\Driver\Command)

The command 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.

Warnung

If you are using a "session" which has a transaction in progress, you cannot specify a "readConcern" or "writeConcern" option. This will result in an MongoDB\Driver\Exception\InvalidArgumentException being thrown. Instead, you should set these two options when you create the transaction with MongoDB\Driver\Session::startTransaction().

Rückgabewerte

Gibt bei Erfolg einen MongoDB\Driver\Cursor zurück.

Fehler/Exceptions

Changelog

Version Beschreibung
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.

Anmerkungen

Hinweis: Es liegt in der Verantwortung des aufrufenden Codes, sicherzustellen, dass der Server in der Lage ist, den Schreibvorgang auszuführen. So schlägt beispielsweise die Ausführung eines Schreibvorgangs auf einem sekundären Server (mit Ausnahme seiner "lokalen" Datenbank) fehl.
