Question

以下是我尝试执行的代码

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所有上述行，但由于某种原因，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

所以，事实证明，答案几乎是正确的。（不是一直吗？） sqlite3.execute命令只需要一个SET，其他的都是冗余的，并且会产生语法错误。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))

Python，sqlite3和UPDATE几行
