更新表与另一个表中的SUM

Question

我想要什么，我想是一个表与另一个表的总和的简单更新，但由于某种原因，它只是更新一行。以下是从表中的相关信息如下所示：

游戏

gameplayer|points 
---------------- 
John  |5 
Jim  |3 
John  |3 
Jim  |4 

playercareer

playercareername|playercareerpoints 
----------------------------------- 
John   |0 
Jim    |0 

现在最后，我想最后的表看起来像这样后运行更新：

player职业

playercareername|playercareerpoints 
----------------------------------- 
John   |8 
Jim    |7 

这是我尝试，只有更新的第一行查询：

UPDATE playercareer 
SET playercareer.playercareerpoints = 
    (
SELECT 
    SUM(games.points) 
FROM games 
    WHERE 
    playercareer.playercareername=games.gameplayer 
    ) 

我似乎无法找到这个问题的答案。预先感谢您的时间和建议！

Answer 1

UPDATE playercareer c 
INNER JOIN (
    SELECT gameplayer, SUM(points) as total 
    FROM games 
    GROUP BY gameplayer 
) x ON c.playercareername = x.gameplayer 
SET c.playercareerpoints = x.total
