如何进行两个查询并结合一个答案？

Question

我的表格如下：tables 输出需要如下所示：output

但是根据Gamer或gsExperiencePoints，我得到的所有代码都是空白答案。我相信我需要将问题分开，然后将答案结合起来，但我不太清楚如何解决这个问题，任何人都能解释如何做到这一点（我不想要答案）

SELECT
    gamerFirst + ' ' + gamerLast as 'Gamer',
    gsExperiencePoints
FROM GAMER
    JOIN GAME_STAT ON GAMER.gamerID = GAME_STAT.gamerID
        JOIN GAME ON GAME_STAT.gameID = GAME.gameID
            JOIN DEVELOPER ON GAME.devID = DEVELOPER.devID
WHERE devName = 'Blizzard Entertainment' AND gsExperiencePoints = (SELECT MAX(gsExperiencePoints) AS gsExperiencePoints FROM GAME_STAT)
GROUP BY gsExperiencePoints, gamerFirst, gamerLast

Answer 1

如果我理解正确，您只需要TOP 1和ORDER BY：

SELECT TOP 1 gamerFirst + ' ' + gamerLast AS Gamer,
       gsExperiencePoints
FROM GAMER g JOIN
     GAME_STAT gs
     ON g.gamerID = gs.gamerID JOIN
     GAME g
     ON gs.gameID = g.gameID JOIN
     DEVELOPER d
     ON g.devID = d.devID
WHERE devName = 'Blizzard Entertainment'
ORDER BY gsExperiencePoints DESC;
