(mongodb >=1.4.0)

MongoDB\Driver\Server::executeReadWriteCommandExecute a database command that reads and writes on this server

Descrizione

final public MongoDB\Driver\Server::executeReadWriteCommand(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 read and write (e.g. » aggregate) and take the MongoDB server version into account. The "readConcern" and "writeConcern" options will default to the corresponding values from the MongoDB Connection URI.

Elenco dei parametri

db (string)

options

options
Option Type Description
readConcern MongoDB\Driver\ReadConcern

A read concern to apply to the operation.

This option is available in MongoDB 3.2+ and will result in an exception at execution time if specified for an older server version.

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.
