This is the implementation of the MySQL data handler for MindsDB.

MySQL is a fast, reliable, and scalable open-source database. It has been in development for more than 25 years and has been used in many production environments since.

​
Implementation

This handler is implemented using the mysql-connector-python library. It’s a Python client for MySQL that doesn’t depend on any MySQL C libraries.

The required arguments to establish a connection are as follows:

  • user is the database user.
  • password is the database password.
  • host is the host name, IP address, or URL.
  • port is the port used to make TCP/IP connection. Default: 3306.
  • database is the database name.

There are several optional arguments that can be used as well.

  • ssl is the ssl parameter value that indicates whether SSL is enabled (True) or disabled (False).
  • ssl_ca is the SSL Certificate Authority.
  • ssl_cert stores SSL certificates.
  • ssl_key stores SSL keys.

If you installed MindsDB locally via pip, you need to install all handler dependencies manually. To do so, go to the handler’s folder (mindsdb/integrations/handlers/mysql_handler) and run this command: pip install -r requirements.txt.

​
Usage

In order to make use of this handler and connect to the MySQL database in MindsDB, the following syntax can be used:

CREATE DATABASE mysql_datasource
WITH
  ENGINE = 'mysql',
  PARAMETERS = {
    "host": "127.0.0.1",
    "port": 3306,
    "database": "mysql",
    "user": "root",
    "password": "password"
  };

You can use this established connection to query your table as follows:

SELECT *
FROM mysql_datasource.example_table;
