Question

我正在尝试使用Python和MySQLdb将一些数据插入到MySQL数据库中。当我在程序中执行以下函数时，MySQL返回错误“1241，'操作数应包含1列'”

用户，密码和数据库是正确的，表格是现有的，所有权利都被授予。

def write_to_mysql(pname, dat, like, reachs, talker, friendsfans):
''
    try:
        con = mdb.connect(user='user', passwd='password', host='localhost', db='database');
    except Exception. err:
        print(err)

    with con:

        cur = con.cursor()
        cur.execute("INSERT INTO fbinsights (page, datum, likes, reach, talking, fanfriends) VALUES( %s, %s, %s, %s, %s, %s)", (pname, dat, like, reachs, talker, friendsfans))

    connection.commit()

哪里出错？

完整追溯：

File "insights.py", line 111, in <module>
    main()
  File "insights.py", line 108, in main
    write_to_mysql(PAGE_NAME, date, likes_atm, reach_day, talking_day, friends_of_fans)
  File "insights.py", line 90, in write_to_mysql
    cur.execute("INSERT INTO fbinsights (page, datum, likes, reach, talking, fanfriends) VALUES( %s, %s, %s, %s, %s, %s)", (pname, dat, like, reachs, talker, friendsfans))

Answer 2

当我使用列生成SELECT查询以在括号中选择括号（错误）时，我遇到此错误：SELECT (id, name, age) FROM members;

请注意，如果括号中只列出一列，则不会引发此错误。

MySQLdb：操作数应包含1列
