mysql.connector.errors.InternalError: Unread result found

from mysql import connector

conn = connector.connect(
            host='xxx.xxx.xxx.xxx',
            port=3306,
            user='xxxxxxx',
            passwd='xxxxxxxxxx',
            db='xxxxxxxxxxxxxxxxx',
            charset='utf8'
            )

cur = conn.cursor()

message_sum = cur.execute("select * from xxxxxxxxxxx")

print(message_sum)

fiveD_upass_tuple = cur.fetchmany(message_sum)

# print(type(fiveD_upass_tuple))

# for fiveD_upass in fiveD_upass_tuple:
#     print(fiveD_upass)

cur.close()
conn.commit()
conn.close()

解决办法

cur = conn.cursor(buffered=True)

加上 buffered=True

即可
