我正在尝试将值列表添加到数据库的表中

QuestionAnswer = [['x','y','z'],['x','y','z']]

(cursor.executemany('INSERT question (QuizID,question,answer) VALUES (%s,%s,%s)',QuestionAnswer)

db.commit()


错误如下:


  追溯(最近一次通话):文件“ C:\ Users \ georgia
  vost \ AppData \ Local \ Programs \ Python \ Python37-32 \ lib \ tkinter__init __。py“,
  1705行,正在通话中

      “失败的处理格式参数;%s”%err)mysql.connector.errors.ProgrammingError:处理失败
  格式参数; Python“方法”无法转换为MySQL类型

最佳答案

现有代码中可能需要进行许多更改,包括查询语法

cursor.executemany('INSERT INTO question (QuizID,question,answer) VALUES (?,?,?)',list(map(tuple,QuestionAnswer)))
