MySqlOperator
=============
Use the :class:`~airflow.providers.mysql.operators.MySqlOperator` to execute
SQL commands in a `MySql <https://dev.mysql.com/doc/>`__ database.
Using the Operator
^^^^^^^^^^^^^^^^^^
Use the ``mysql_conn_id`` argument to connect to your MySql instance where
the connection metadata is structured as follows:
.. list-table:: MySql 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
- MySql user
* - Password: string
- MySql user password
* - Port: int
- MySql port
An example usage of the MySqlOperator is as follows:
.. exampleinclude:: /../../airflow/providers/mysql/example_dags/example_mysql.py
:language: python
:start-after: [START howto_operator_mysql]
:end-before: [END howto_operator_mysql]
You can also use an external file to execute the SQL commands. Script folder must be at the same level as DAG.py file.
.. exampleinclude:: /../../airflow/providers/mysql/example_dags/example_mysql.py
:language: python
:start-after: [START howto_operator_mysql_external_file]
:end-before: [END howto_operator_mysql_external_file]
.. note::
Parameters that can be passed onto the operator will be given priority over the parameters already given
in the Airflow connection metadata (such as ``schema``, ``login``, ``password`` and so forth).
