Python、sqlite3 和 UPDATE 几行

Question

这是我要执行的代码

db.execute('''UPDATE WARDWINS \
    SET map = ?, 
    SET team1wards = ?, 
    SET team2wards = ?, 
    SET mostwards = ?, 
    SET winningteam = ?, 
    SET mostwardswin = ? 
    where matchID = ?''', (dic['mapID'][0], dic['team1wards'], dic['team2wards'], dic['mostwards'], dic['winningteam'], dic['wardswins'], match))

我想要实现的是让一个执行命令同时更新以上所有行，但出于某种原因我似乎无法弄清楚如何做到这一点。我收到以下错误消息：

>>> dic['mostwards'], dic['winningteam'], dic['wardswins'], match))
sqlite3.OperationalError: near "SET": syntax error

Answer 1

事实证明，答案几乎是正确的。（不总是这样吗？） sqlite3.execute 命令只需要一个 SET，其他的都是多余的，并且会造成语法错误。正确的做法如下：

db.execute('''UPDATE WARDWINS \
    SET map = ?, 
    team1wards = ?, 
    team2wards = ?, 
    mostwards = ?, 
    winningteam = ?, 
    mostwardswin = ? 
    where matchID = ?''', (dic['mapID'][0], dic['team1wards'], dic['team2wards'], dic['mostwards'], dic['winningteam'], dic['wardswins'], match))
