(mongodb >=1.4.0)

MongoDB\Driver\Manager::executeReadWriteCommandExecute a database command that reads and writes

Beschreibung

final public MongoDB\Driver\Manager::executeReadWriteCommand ( string $db , MongoDB\Driver\Command $command [, array $options = array() ] ) : MongoDB\Driver\Cursor

Executes the command on the primary server.

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

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
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.

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().

R├╝ckgabewerte

Returns MongoDB\Driver\Cursor on success.

Fehler/Exceptions

Changelog

Version Beschreibung
1.4.4 MongoDB\Driver\Exception\InvalidArgumentException will be thrown if the "session" option is used in combination with an unacknowledged write concern.
