MongoDB::command — Execute a database command

Описание

Almost everything that is not a CRUD operation can be done with a database command. Need to know the database version? There's a command for that. Need to do aggregation? There's a command for that. Need to turn up logging? You get the idea.

This method is identical to:

public function command($data) {
    return $this->selectCollection('$cmd')->findOne($data);
}

Список параметров

command -

The query to send.

options -

This parameter is an associative array of the form array("optionname" => <boolean>, ...). Currently supported options are:

• "timeout"

  Integer, defaults to Mongo::$timeout. If "safe" is set, this sets how long (in milliseconds) for the client to wait for a database response. If the database does not respond within the timeout period, a MongoCursorTimeoutException will be thrown.
