我正在尝试使用 Python 和 MySQLdb 将一些数据插入 MySQL 数据库。当我在我的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、密码和数据库正确，表存在且授予所有权限。

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()

哪里错了？

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))
  File "/usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-freebsd-9.0-RELEASE-p3-amd64.egg/MySQLdb/cursors.py", line 174, in execute

@schlamar 回答了它。错误的类型传递给 MySQL。

当我生成一个SELECT查询时，我遇到了这个错误，其中的列选择括在括号中（错误地）SELECT (id, name, age) FROM members：;

请注意，如果括号中仅列出一列，则不会引发此错误。
