獲取所有WHERE在一個查詢案件

Question

我有了這個查詢

SELECT users.name 
FROM users 
LEFT JOIN weapon_stats ON users.id = weapon_stats.zp_id 
WHERE weapon_stats.weapon = 26 
ORDER BY weapon_stats.kills DESC 
LIMIT 1; 

它使y需要得到的結果變化，其中從1到30，那奇怪的問題..

是否有可能在一個查詢中獲得所有結果？

我想大多數殺死每個用戶每一種武器

武器1

SELECT users.name 
FROM users 
LEFT JOIN weapon_stats ON users.id = weapon_stats.zp_id 
WHERE weapon_stats.weapon = 01 
ORDER BY weapon_stats.kills DESC 
LIMIT 1; 

武器2

SELECT users.name 
FROM users 
LEFT JOIN weapon_stats ON users.id = weapon_stats.zp_id 
WHERE weapon_stats.weapon = 02 
ORDER BY weapon_stats.kills DESC 
LIMIT 1; 

提前感謝！

Answer 1

select U.name, W.weapon, W.kills 
FROM users U 
INNER JOIN weapons W on W.zp_id = U.id 
INNER JOIN 
    (SELECT WW.weapon, MAX(WW.kills) AS kills 
    FROM weapons WW 
    WHERE WW.weapon BETWEEN 1 AND 30 
    GROUP BY WW.weapon) K 
    ON W.kills = K.kills AND W.weapon = K.weapon 

我敢肯定，它可以製成通過優化速度更快，但這個最後的作品

Answer 2

WHERE weapon_stats.weapon BETWEEN 1 AND 30 

Answer 3

我不知道你的意思是通過不斷變化的，其中從1到30 '但看到以下內容：

[..] WHERE wearpon_stats.weapon BETWEEN 1 AND 30;

Answer 4

除非我誤解你在找什麼，你就不能下？

SELECT users.name 
FROM users 
LEFT JOIN weapon_stats ON users.id = weapon_stats.zp_id 
WHERE weapon_stats.weapon BETWEEN 1 and 30 
ORDER BY weapon_stats.kills DESC 
LIMIT 1;
