Cannot commit a read statement (3 replies)

```
>>> import mysql.connector
>>> cnx = mysql.connector.connect(user="root")
>>> cur = cnx.cursor()
>>> cur.execute('select count(*) from test.test')
>>> cnx.commit()
Traceback (most recent call last):

```

commit a select statement always return a "Unread result found" error. Is this expected? Same code works well with mysqlclient and PyMySQL.
