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

Similarly to the :class:`~airflow.providers.snowflake.operators.snowflake.SnowflakeOperator`, use the ``snowflake_conn_id`` and
the additional relevant parameters to establish connection with your Snowflake instance.
This operator will execute a custom query on a selected Snowflake table and publish a Slack message that can be formatted
and contain the resulting dataset (e.g. ASCII formatted dataframe).

An example usage of the SnowflakeToSlackOperator is as follows:

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