我怎么能没有得到mysql转换元组错误？

Question

我只想使用UPDATE命令刷新。这给出了错误，我在哪里犯错误？

for checkNewAbility in list(newAbilities1):
    if not checkNewAbility in list(oldAbility[1]):
        my_cursor.execute(
           "UPDATE mydb.skill SET skill_name='%s' WHERE Person_person_id='%s' 
                AND skill_id='%d';",(checkNewAbility, url[0], oldAbility[0]))
        realdb.commit()

错误：

“处理格式参数失败;％s”％错误）mysql.connector.errors.ProgrammingError：处理格式参数失败; Python'tuple'无法转换为MySQL类型

我的名单有：

oldAbility = [（43，'PHP'），（44，'HTML'），（45，'CSS'）]

newAbilities1 = ['Java'，'Python'，'JavaScript']

我只想根据id用newAbilities1替换oldAbilities。

如果你正确地复制并粘贴你的代码，那么在执行后会丢失双引号（“我假设你使用了pyodbc。

for checkNewAbility in list(newAbilities1):
    if not checkNewAbility in list(oldAbility[1]):
        my_cursor.execute("UPDATE mydb.skill SET skill_name='?' WHERE Person_person_id='?' AND skill_id='?'", (checkNewAbility, url[0], oldAbility[0]))
        realdb.commit()
