SQLExecuteQueryOperator to connect to Oracle

Use the :class:SQLExecuteQueryOperator<airflow.providers.common.sql.operators.sql> to execute Oracle commands in a Oracle <https://docs.oracle.com/en/>__ database.

.. note:: Previously, OracleStoredProcedureOperator 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 Oracle instance where the connection metadata is structured as follows:

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

• • Parameter
  • Input
• • Host: string
  • Oracle database hostname
• • Schema: string
  • Schema to execute SQL operations on by default
• • Login: string
  • Oracle database user
• • Password: string
  • Oracle database user password
• • Port: int
  • Oracle database port (default: 1521)
• • Extra: JSON
  • Additional connection configuration, such as DSN string: {"dsn": "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=<hostname>)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=<service_name>)))"}

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

.. exampleinclude:: /../../oracle/tests/system/oracle/example_oracle.py :language: python :start-after: [START howto_operator_oracle] :end-before: [END howto_operator_oracle]

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

• Oracle Documentation <https://docs.oracle.com/en/>__

.. note::

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