For more information on how to use this operator, take a look at the guide:
:ref:`howto/operator:MsSqlOperator`
This operator may use one of two hooks, depending on the ``conn_type`` of the connection.
If conn_type is ``'odbc'``, then :py:class:`~airflow.providers.odbc.hooks.odbc.OdbcHook`
is used. Otherwise, :py:class:`~airflow.providers.microsoft.mssql.hooks.mssql.MsSqlHook` is used.
:param sql: the sql code to be executed (templated)
:param mssql_conn_id: reference to a specific mssql database
:param parameters: (optional) the parameters to render the SQL query with.
:param autocommit: if True, each command is automatically committed.
(default value: False)
:param database: name of database which overwrite defined one in connection
