Answer 1

If anyone is getting this error after a Phpmyadmin export, using the custom options and adding the "drop tables" statements cleared this right up.

Answer 2

As already stated, it's a warning not an error, but (if like me) you want things to run without warnings, you can disable that warning, then re-enable it again when you're done.

SET sql_notes = 0;      -- Temporarily disable the "Table already exists" warning
CREATE TABLE IF NOT EXISTS ...
SET sql_notes = 1;      -- And then re-enable the warning again

Answer 3

Create mysql connection with following parameter. "'raise_on_warnings': False". It will ignore the warning. e.g.

config = {'user': 'user','password': 'passwd','host': 'localhost','database': 'db',   'raise_on_warnings': False,}
cnx = mysql.connector.connect(**config)
