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).
