MongoDB\Driver\Manager::executeWriteCommand — Execute a database command that writes
$db, MongoDB\Driver\Command $command, ?array $options = null): MongoDB\Driver\CursorExecutes the command on the primary server.
   This method will apply logic that is specific to commands that write (e.g.
   » drop).
   The default value for the "writeConcern" option will be
   inferred from an active transaction (indicated by the
   "session" option), followed by the
   connection URI.
  
Note: This method is not intended to be used to execute » insert, » update, or » delete commands. Users are encouraged to use MongoDB\Driver\Manager::executeBulkWrite() for those operations.
db (string)The name of the database on which to execute the command.
command (MongoDB\Driver\Command)The command to execute.
options
| Option | Type | Description | 
|---|---|---|
| session | MongoDB\Driver\Session | A session to associate with the operation. | 
| writeConcern | MongoDB\Driver\WriteConcern | A write concern to apply to the operation. | 
       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().
      
Returns MongoDB\Driver\Cursor on success.
"session" option is used with an associated transaction in combination with a "readConcern" or "writeConcern" option."session" option is used in combination with an unacknowledged write concern.
| Version | Description | 
|---|---|
| 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. |
