    说明

    finalpublicMongoDB\Driver\Manager::executeReadWriteCommand(string$db, MongoDB\Driver\Command$command, ?array$options = null): 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. » 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.

    警告

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().
