9.5.1 Constructor cursor.MySQLCursor

In most cases, the MySQLConnection cursor() method is used to instantiate a MySQLCursor object:

import mysql.connector

cnx = mysql.connector.connect(database='world')
cursor = cnx.cursor()

It is also possible to instantiate a cursor by passing a MySQLConnection object to MySQLCursor:

import mysql.connector
from mysql.connector.cursor import MySQLCursor

cnx = mysql.connector.connect(database='world')
cursor = MySQLCursor(cnx)

The connection argument is optional. If omitted, the cursor is created but its execute() method raises an exception.
