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 = 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). The default value for the "writeConcern" option will be inferred from an active transaction (indicated by the "session" option), followed by the 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 operations.

Elenco dei parametri

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.

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.
