MongoDB\Driver\Manager::executeWriteCommand — Execute a database command that writes
说明
$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 write (e.g. » drop) and take the MongoDB server version into account. The "writeConcern" option will default to the corresponding value from the MongoDB Connection URI.
参数
-
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 session MongoDB\Driver\Session A session to associate with the operation.
writeConcern MongoDB\Driver\WriteConcern A write concern to apply to the operation.
WarningIf 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().
返回值
Returns MongoDB\Driver\Cursor on success.

- Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
- Throws MongoDB\Driver\Exception\ConnectionException if connection to the server fails (for reasons other than authentication).
- Throws MongoDB\Driver\Exception\AuthenticationException if authentication is needed and fails.
