How to use "mysql.connector" module produced by mysql.com?

"mysql.connector" is the official Python module provided by mysql.com for MySQL database connection. You can follow this tutorial to try it.

1. Install "mysql-connector-python" package that contains the "mysql.connector" module. Do not use the outdated "mysql-connector" package.

fyicenter> pip3 install mysql-connector-python

...
Successfully installed mysql-connector-python-8.0.23 protobuf-3.15.6

2. Start a Python 3 interactive session and import the "mysql.connector" module.

fyicenter> python3 
Python 3.8.0 (v3.8.0:fa919fdf25) 

>>> import mysql.connector

>>> mysql.connector.1.03
'8.0.23'

3. Call the connect() method to establish a connection to a MySQL server with given accessing information. It returns a MySQLConnection object representing the established connection.

>>> con = mysql.connector.connect(host="127.0.0.1", port=3306,
...     user="guest", password="retneciyf")

>>> print(con)
<mysql.connector.connection.MySQLConnection object at 0x10701b640>

4. Use MySQLConnection methods and properties to see the MySQL environment.

>>> con.get_server_info()
'8.0.17'

>>> con.cmd_statistics()
{'Uptime': 1726469, 'Threads': 4, 'Questions': 64496, 'Slow queries': 0,
   ...

>>> con.user
'guest'

>>> con.charset
'utf8mb4'

5. Call cmd_init_db() method to set the default database to a database instance that your user name is allowed to use.

>>> con.cmd_init_db("test")
{'field_count': 0, 'affected_rows': 0, 'insert_id': 0, ...

>>> con.database
'test'

6. Run SQL statements on the connection as shown in next tutorials.

7. Close the connection at the end.

>>> con.is_connected() 
True 

>>> con.close()

>>> con.is_connected() 
False
