如何加入mysql複選框表A和另一個表B中的複選框結果字段？

Question

我有表按本sqlFiddle： http://www.sqlfiddle.com/#!2/df04a/1

Onepiece table: 

| ID | Checkbox_IDs | 
| 1 | 1,2    | 
| 2 | 3    | 

checkbox 
| ID | Name   | 
| 1 | Luffy   | 
| 2 | Zorro   | 

請幫我查詢，我想一切從「一件式」表，而不是checkbox_id欄顯示「1,2行「或 」2,3,4「，它應該表現出什麼樣的數字鏈接上的複選框表：

Onepiece results table: 

| ID | Checkbox_IDs | 
| 1 | Luffy, Zorro | 
| 2 | Sanji   | 

Answer 1

SELECT a.ID, 
     GROUP_CONCAT(b.Name) Names 
FROM OnePiece a 
     INNER JOIN CheckBoxes b 
      ON FIND_IN_SET(b.ID, a.Checkbox_ID) > 0 
GROUP BY a.ID 

• SQLFiddle Demo
• MySQL FIND_IN_SET

輸出
