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. zGet the exception matching the MySQL error This function will return an exception based on the SQLState. The given message will be passed on in the returned exception. The exception returned can be customized using the mysql.connector.custom_error_exception() function.
