def custom_error_exception(error=None, exception=None) 

Description

custom_error_exception.__doc__

Define custom exceptions for MySQL server errors

    This function defines custom exceptions for MySQL server errors and
    returns the current set customizations.

    If error is a MySQL Server error number, then you have to pass also the
    exception class.

    The error argument can also be a dictionary in which case the key is
    the server error number, and value the exception to be raised.

    If none of the arguments are given, then custom_error_exception() will
    simply return the current set customizations.

    To reset the customizations, simply supply an empty dictionary.

    Examples:
        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,
            })

        # Reset
        mysql.connector.custom_error_exception({})

    Returns a dictionary.
