Mysql SQL从多个表中获取值，然后对其排序

我想做一个MySQL查询。我有4张桌子：A、B、C、D

我想从“account”=1的所有4个表中获得公共值：“wins”，然后按大多数“wins”排序。所有订购的“胜利”限制为3

如果你帮助我，我会非常高兴

我试过这样的方法：

SELECT o.*
FROM (
(SELECT wins FROM 'A')
UNION ALL
(SELECT wins FROM 'B')
UNION ALL
(SELECT wins FROM 'C')
UNION ALL
(SELECT wins FROM 'D')
UNION ALL
(SELECT * FROM 'A'
WHERE
    account=1) 
) AS o
ORDER BY wins DESC

---

但这确实是错误的。

如果您需要了解从中获得结果的表格：

SELECT *
FROM (  SELECT wins, 'Table A' AS DataTable
        FROM TableA
        WHERE account = 1
        UNION ALL
        SELECT wins, 'Table B' 
        FROM TableB
        WHERE account = 1
        UNION ALL
        SELECT wins, 'Table C' 
        FROM TableC
        WHERE account = 1
        UNION ALL
        SELECT wins, 'Table D' 
        FROM TableD
        WHERE account = 1) AS X
ORDER BY wins
LIMIT 3

如果这并不重要，而您只需要最高级别的

：

SELECT *
FROM (  SELECT wins
        FROM TableA
        WHERE account = 1
        UNION
        SELECT wins
        FROM TableB
        WHERE account = 1
        UNION
        SELECT wins
        FROM TableC
        WHERE account = 1
        UNION
        SELECT wins
        FROM TableD
        WHERE account = 1) AS X
ORDER BY wins DESC
LIMIT 3

你试过什么吗？你试过联合吗？听上去，你的数据库设置不正确。为了什么目的将相同的信息传播到四个不同的表中？在不同的表中使用相同的名称是有原因的。显示表结构和一些示例数据以及预期的输出。而且更可取的是，你已经尝试过的东西不起作用。
