MySQL查詢顯示其ID的具有特定記錄

Question

很抱歉的模糊標題，不知道怎麼回事來形容它

基本上我有這樣的（汽車用分離^^）表

id| cars 
------------------------- 
1|car1 ^^ car2 ^^ car3 
2|car2 ^^ car3 
3|car1 
4|car1 ^^ car 2 
5|car3 

基本上我想列出所有的汽車行駛它們匹配喜歡這個

car |id 
------------- 
car1|1,3,4 
car2|1,2,4 
car3|1,2,5 

這是可能在MySQL中做，什麼將是它的查詢ID的？

任何幫助非常感謝！

這應該工作。我使用表變量「@Cars」填充我的結果，但是，您可以用數據庫中的實際表名替換它。

--Table Defination: 
    DECLARE @Cars TABLE 
    (ID INT IDENTITY, 
    Cars VARCHAR(255) 
    ); 
    INSERT INTO @Cars(Cars) 
    VALUES('car1 ^^ car2 ^^ car3'); 
    INSERT INTO @Cars(Cars) 
    VALUES('car2 ^^ car3'); 
    INSERT INTO @Cars(Cars) 
    VALUES('car1'); 
    INSERT INTO @Cars(Cars) 
    VALUES('car1 ^^ car2'); 
    INSERT INTO @Cars(Cars) 
    VALUES('car3'); 

--SQL 
    SELECT distinct Cars, STUFF(
       (
        SELECT ', '+CAST([id] AS NVARCHAR(256)) 
        FROM 
        (
         SELECT A.id, 
           LTRIM(RTRIM(Split.a.value('.', 'VARCHAR(100)'))) AS Cars 
         FROM 
         (
          SELECT ID, 
            CAST('<M>'+REPLACE(Cars, '^^', '</M><M>')+'</M>' AS XML) AS String 
          FROM @Cars 
         ) AS A 
         CROSS APPLY String.nodes('/M') AS Split(a) 
        ) T1 
        WHERE T1.Cars = T2.Cars 
        FOR XML PATH('') 
       ), 1, 1, '') AS id 
    FROM 
    (
     SELECT A.id, 
       LTRIM(RTRIM(Split.a.value('.', 'VARCHAR(100)'))) AS Cars 
     FROM 
     (
      SELECT ID, 
        CAST('<M>'+REPLACE(Cars, '^^', '</M><M>')+'</M>' AS XML) AS String 
      FROM @Cars 
     ) AS A 
     CROSS APPLY String.nodes('/M') AS Split(a) 
    ) T2;
