MySQL Connector/Python Developer Guide
Syntax:
errors.custom_error_exception(error=None, exception=None)
This method defines custom exceptions for MySQL server errors and returns current customizations.
If error
is a MySQL Server error number, you
must also pass the exception
class. The
error
argument can be a dictionary, in which
case the key is the server error number, and value the class of
the exception to be raised.
To reset the customizations, supply an empty dictionary.
import mysql.connector from mysql.connector import errorcode # Server error 1028 should raise a DatabaseError mysql.connector.custom_error_exception(1028, mysql.connector.DatabaseError) # Or using a dictionary: mysql.connector.custom_error_exception({ 1028: mysql.connector.DatabaseError, 1029: mysql.connector.OperationalError, }) # To reset, pass an empty dictionary: mysql.connector.custom_error_exception({})
