SnowflakeOperator
=================

Use the :class:`SnowflakeOperator <airflow.providers.snowflake.operators.snowflake>` to execute
SQL commands in a `Snowflake <https://docs.snowflake.com/en/>`__ database.


Using the Operator
^^^^^^^^^^^^^^^^^^

Use the ``snowflake_conn_id`` argument to connect to your Snowflake instance where
the connection metadata is structured as follows:

.. list-table:: Snowflake Airflow Connection Metadata
   :widths: 25 25
   :header-rows: 1

   * - Parameter
     - Input
   * - Login: string
     - Snowflake user name
   * - Password: string
     - Password for Snowflake user
   * - Schema: string
     - Set schema to execute SQL operations on by default
   * - Extra: dictionary
     - ``warehouse``, ``account``, ``database``, ``region``, ``role``, ``authenticator``

An example usage of the SnowflakeOperator is as follows:

.. exampleinclude:: /../../airflow/providers/snowflake/example_dags/example_snowflake.py
    :language: python
    :start-after: [START howto_operator_snowflake]
    :end-before: [END howto_operator_snowflake]

.. note::

  Parameters that can be passed onto the operator will be given priority over the parameters already given
  in the Airflow connection metadata (such as ``schema``, ``role``, ``database`` and so forth).
