DatabricksSqlOperator
=====================

Use the :class:`~airflow.providers.databricks.operators.databricks_sql.DatabricksSqlOperator` to execute SQL
on a `Databricks SQL endpoint  <https://docs.databricks.com/sql/admin/sql-endpoints.html>`_ or a
`Databricks cluster <https://docs.databricks.com/clusters/index.html>`_.


Using the Operator
------------------

Operator executes given SQL queries against configured endpoint. The only required parameters are:

* ``sql`` - SQL queries to execute. There are 3 ways of specifying SQL queries:

  1. Simple string with SQL statement.
  2. List of strings representing SQL statements.
  3. Name of the file with SQL queries. File must have ``.sql`` extension. Each query should finish with ``;<new_line>``

* One of ``sql_endpoint_name`` (name of Databricks SQL endpoint to use) or ``http_path`` (HTTP path for Databricks SQL endpoint or Databricks cluster).

Other parameters are optional and could be found in the class documentation.
