MySQL從不同的表聯接數據

Question

好的，我從mySQl數據庫中提取了一個用戶列表，然后在另一個表中尋找組分配。 如果將它們分配給多個組，則應返回多行。

我的問題是如何將組名稱合並到結果的一欄中。

  SELECT `u`.`ID`
         ,CONCAT(`First-Name`," ",`Last-Name`) as `Name`
         ,`g`.`Group-Name`
    FROM `application-users` AS `u`
    JOIN `groups` AS `g` ON (`g`.`Assigned-Users` LIKE CONCAT("%|",`u`.`ID`,"|%") )
   WHERE `u`.`Status` = "Active" && `u`.`Type` = "Business Development" 
ORDER BY `First-Name` ASC

提前致謝！

Answer 1

SELECT `u`.`ID`,CONCAT(`First-Name`," ",`Last-Name`) as `Name`,
GROUP_CONCAT(`g`.`Group-Name` SEPARATOR ', ') as `Groups`,
CONCAT('|',GROUP_CONCAT(`g`.`ID` SEPARATOR '|'),'|') as `GroupIDs`
FROM `application-users` AS `u`
JOIN `groups` AS `g` ON (`g`.`Assigned-Users` LIKE CONCAT("%|",`u`.`ID`,"|%"))
WHERE `u`.`Status` = "Active" && `u`.`Type` = "Business Development" 
GROUP BY `u`.`ID`

感謝您的寶貴時間！
