SqliteOperator
==============

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


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

Use the ``sqlite_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
     - MySql hostname
   * - Schema: string
     - Set schema to execute Sql operations on by default
   * - Login: string
     - Sqlite user
   * - Password: string
     - Sqlite user password
   * - Port: int
     - Sqlite port

An example usage of the SqliteOperator is as follows:

.. exampleinclude:: /../../airflow/providers/sqlite/example_dags/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:: /../../airflow/providers/sqlite/example_dags/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 SqliteOperator() are given first-place priority
  relative to parameters set via Airflow connection metadata (such as ``schema``, ``login``, ``password`` etc).
