mysql - 如何SELECT FROM多个子查询结果的交集？

Question

首先，好消息:我只有一张 table 。

现在，我有 3 个类似的查询:

SELECT id FROM (
  SELECT * FROM my_table
  ORDER BY columnA
  DESC LIMIT 600
  ) AS aliasA
WHERE (revenue > 10000);

SELECT id FROM (
  SELECT * FROM my_table
  ORDER BY columnB
  DESC LIMIT 400, 999999999999
  ) AS aliasB
WHERE (revenue > 10000);

SELECT id FROM (
  SELECT * FROM my_table
  ORDER BY columnC
  DESC LIMIT 800;
  ) AS aliasC
WHERE (revenue > 10000);

注意 WHERE 子句是相同的。

有没有办法组合这 3 个查询，以便我可以从 3 个子查询的交集进行搜索(查找与所有 3 个子查询以及我的 WHERE 子句匹配的行)？

顺便说一下，如果我的单个查询(合并前)可以简化，请告诉我。

谢谢!

Answer 1

SELECT ID FROM

(SELECT id FROM (
    SELECT * 
    FROM my_table
    WHERE (revenue > 10000)
    ORDER BY columnA DESC 
   LIMIT 600
) AS aliasA) AS a

INNER JOIN (
  SELECT id FROM (
     SELECT * 
     FROM my_table
     WHERE (revenue > 10000)
     ORDER BY columnB DESC
     LIMIT 400, 999999999999
  ) AS aliasB
) 
AS b ON a.id = b.id

INNER JOIN (
  SELECT id FROM (
    SELECT * 
    FROM my_table
    WHERE (revenue > 10000)
    ORDER BY columnC DESC
    LIMIT 800
  ) AS aliasC
) 
AS c ON a.id = c.id AND b.id = c.id

然后你可以搜索这个query
