MongoDB\Driver\Manager::executeReadWriteCommand — Execute a database command that reads and writes

### Descrierea

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.

### Parametri

`db` (string)

  Denumirea bazei de date asupra căreia va fi executată comanda.

`command` (MongoDB\Driver\Command)

  MongoDB\Driver\Command spre a fi executată.

`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.

  Avertizare

  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().
