php - 选择匹配值超过 4 列的球员

标签 php mysql sql

我想选择一个有 10 列的表中的所有玩家，其中玩家是关键，如果他们有超过 4 个匹配列。例如，如果 col1、col2、col3 和 col4 匹配，则列出具有相同列的所有用户，但如果 col1、col5、col4 和 col8 匹配，则还列出具有相同列的所有用户。所以基本上，如果玩家与其他玩家至少有 4 个匹配列，无论 col1 = col1 还是 col8 = col8 都会显示具有匹配列的用户

最佳答案

如果我正确地理解了您的问题，您希望查找在同一个表中超过 4 列共享相同值的记录。 由于 GROUP BY 和 COUNT() 将充当复合键，因此它只能找到分组的所有列的精确匹配。

我认为正如@Orangepill 在评论中提到的。最简单的方法是将生成的匹配列值相加，与同一个表上的联接相关，以比较不同的值，然后使用 DISTINCT 和 限制匹配值的结果>拥有。

SELECT DISTINCT 
 m.`user`,
 m.gpuid,
 m.cpuid,
 m.winkey,
 m.desktopname,
 m.windowsuser,
 m.bios,
 m.processor,
 m.video
FROM (
    SELECT p.*, (
      (p.gpuid = p2.gpuid) + 
      (p.cpuid = p2.cpuid) + 
      (p.winkey = p2.winkey) + 
      (p.desktopname = p2.desktopname) + 
      (p.windowsuser = p2.windowsuser) + 
      (p.bios = p2.bios) + 
      (p.processor = p2.processor) + 
      (p.video = p2.video)
    ) AS matches 
    FROM `table` AS p
    LEFT JOIN  `table` AS p2
    ON p.`user` != p2.`user`
    HAVING matches > 4
) AS m
