MongoDB\Driver\Server::executeWriteCommand

(mongodb >=1.4.0)

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

Descrizione

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

Nota: 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.

Elenco dei parametri

db (string)

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

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.

Avviso

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().

Valori restituiti

Returns MongoDB\Driver\Cursor on success.

Errori/Eccezioni

Log delle modifiche

Versione Descrizione
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.

Note

Nota: It is the caller's responsibility to ensure that the server is capable of executing the write operation. For example, executing a write operation on a secondary (excluding its "local" database) will fail.
