SQLExecuteQueryOperator to connect to Sqlite
============================================

Use the :class:`SQLExecuteQueryOperator<airflow.providers.common.sql.operators.sql>` to execute
Sqlite commands in a `Sqlite <https://sqlite.org/lang.html>`__ database.

.. note::
    Previously, ``SqliteOperator`` was used to perform this kind of operation. After deprecation this has been removed. Please use ``SQLExecuteQueryOperator`` instead.

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

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

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

   * - Parameter
     - Input
   * - Host: string
     - Sqlite database file

An example usage of the SQLExecuteQueryOperator to connect to Sqlite is as follows:

.. exampleinclude:: /../../sqlite/tests/system/sqlite/example_sqlite.py
    :language: python
    :start-after: [START howto_operator_sqlite]
    :end-before: [END howto_operator_sqlite]

Furthermore, you can use an external file to execute the SQL commands. Script folder must be at the same level as DAG.py file.

.. exampleinclude:: /../../sqlite/tests/system/sqlite/example_sqlite.py
    :language: python
    :start-after: [START howto_operator_sqlite_external_file]
    :end-before: [END howto_operator_sqlite_external_file]

Reference
^^^^^^^^^
For further information, look at:

* `Sqlite Documentation <https://www.sqlite.org/index.html>`__

.. note::

  Parameters given via SQLExecuteQueryOperator() are given first-place priority
  relative to parameters set via Airflow connection metadata (such as ``schema``, ``login``, ``password`` etc).
