| SqliteOperator |
| ============== |
| |
| Use the :class:`~airflow.providers.sqlite.operators.sqlite.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 |
| - Sqlite database file |
| |
| An example usage of the SqliteOperator is as follows: |
| |
| .. exampleinclude:: /../../tests/system/providers/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:: /../../tests/system/providers/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 SqliteOperator() are given first-place priority |
| relative to parameters set via Airflow connection metadata (such as ``schema``, ``login``, ``password`` etc). |
