Executes an SQL statement in Snowflake and sends the results to Slack. The results of the query are

class airflow.providers.snowflake.transfers.snowflake_to_slack.SnowflakeToSlackOperator(*, sql, slack_message, snowflake_conn_id='snowflake_default', slack_conn_id='slack_default', results_df_name='results_df', parameters=None, warehouse=None, database=None, schema=None, role=None, slack_token=None, **kwargs)[source]

Bases: airflow.providers.slack.transfers.sql_to_slack.SqlToSlackOperator

Executes an SQL statement in Snowflake and sends the results to Slack. The results of the query are rendered into the ‘slack_message’ parameter as a Pandas dataframe using a JINJA variable called ‘{{ results_df }}’. The ‘results_df’ variable name can be changed by specifying a different ‘results_df_name’ parameter. The Tabulate library is added to the JINJA environment as a filter to allow the dataframe to be rendered nicely. For example, set ‘slack_message’ to {{ results_df | tabulate(tablefmt=”pretty”, headers=”keys”) }} to send the results to Slack as an ascii rendered table.

  • sql (str) – The SQL statement to execute on Snowflake (templated)

  • slack_message (str) – The templated Slack message to send with the data returned from Snowflake. You can use the default JINJA variable {{ results_df }} to access the pandas dataframe containing the SQL results

  • snowflake_conn_id (str) – Reference to Snowflake connection id

  • slack_conn_id (str) – The connection id for Slack.

  • results_df_name (str) – The name of the JINJA template’s dataframe variable, default is ‘results_df’

  • parameters (Iterable | Mapping | None) – The parameters to pass to the SQL query

  • warehouse (str | None) – The Snowflake virtual warehouse to use to run the SQL query

  • database (str | None) – The Snowflake database to use for the SQL query

  • schema (str | None) – The schema to run the SQL against in Snowflake

  • role (str | None) – The role to use when connecting to Snowflake

  • slack_token (str | None) – The token to use to authenticate to Slack. If this is not provided, the ‘webhook_token’ attribute needs to be specified in the ‘Extra’ JSON field against the slack_conn_id.
