如何用不同的ID來爆炸行？

Question

我需要幫助。我的Qurum表

qurum table    data table 
qurum_id|qurum   id|qurum1 
     1|one    1|3 
     2|two    2|2 
     3|three    3|1 
     4|four    4|7 
     5|five    5|5,6 
     6|six    6|4 
     7|seven    7|5 
where qurum_id = data.qurum1 

的結果必須是

qurum_id|qurum|qurum1 
     1|one |3 
     2|two |2 
     3|three|1 
     4|four |7 
     5|five |5 
    **6|six |6 
     6|six |4** 
     7|seven|5 

這是查詢

`SELECT qurum_id, qurum,qurum1, 
     SUM(CASE WHEN DATE_FORMAT(aa.input_date, '%m') BETWEEN 01 AND 06 
      THEN 1 END) AS I, 
     SUM(CASE WHEN DATE_FORMAT(aa.input_date, '%m') BETWEEN 07 AND 12 
      THEN 1 END) AS II 
FROM qurum AS qur 
INNER JOIN (SELECT id, qurum1,input_date FROM DATA) AS aa 
      ON qur.qurum_id = aa.qurum1 
WHERE DATE_FORMAT(aa.input_date, '%Y') = $year 
GROUP BY qurum_id 
ORDER BY qurum_id` 

結果是here

有第六行與qurum1 = 6 | 7在表中，但我需要爆炸6 | 7，因爲qurum_id 6和qurum_id 7有不同的qurum。 PIC將show盡我想說

Answer 1

SELECT SUBSTRING_INDEX(qurum1, ' ', 1) AS first_part, 
SUBSTRING_INDEX(qurum1, ' ', -1) as second_part FROM qurum;
