Question

是否可以用一行更新SQL中的多个字段。

这是一个例子：

"UPDATE badgeownedbadges SET badgeID =(SELECT badgeID FROM badges WHERE badgename=%s) SET scoutID = (SELECT scoutID FROM scoutinfo WHERE firstname=%s AND secondname=%s)"

将％s作为适用变量

是的，就像使用select查询一样，只需使用逗号分隔字段即可：

UPDATE badgeownedbadges 
SET 
    badgeID = (SELECT badgeID FROM badges WHERE badgename=%s),
    scoutID = (SELECT scoutID FROM scoutinfo WHERE firstname=%s AND secondname=%s)

UPDATE语句可连续更新多个字段
