如何在MySQL中組合這兩個查詢？

Question

好吧，我是小白，我接受。但我試圖結合這兩個查詢，由於某種原因，我不明白如何。

查詢1.

select t.id from tickets t 

查詢2.

SELECT name 
FROM groups 
WHERE id = (
      SELECT DISTINCT immediateparentid 
      FROM cachedgroupmembers c 
      LEFT JOIN groups g 
      ON c.groupid = g.id 
      LEFT JOIN tickets t 
      ON t.id = g.instance 
      WHERE t.Id = 1234 
      AND g.type = 'AdminCc' 
      AND immediateparentid <> c.groupid 
     ) 

在第一查詢中的票ID是第二的where子句中被使用。有沒有辦法將這兩個查詢結合起來？

Answer 1

SELECT 
     g.name, 
     (SELECT id FROM tickets) as ID 
FROM groups as g 
WHERE id = (
      SELECT 
       DISTINCT immediateparentid 
      FROM cachedgroupmembers c 
      LEFT JOIN groups g ON c.groupid = g.id 
      LEFT JOIN tickets t ON t.id = g.instance 
      WHERE t.Id = ID 
      AND g.type = 'AdminCc' 
      AND immediateparentid <> c.groupid 
     )  

這是一個依賴子查詢
