SQL查詢給我錯誤的順序

Question

為什么我無法通過此查詢獲得所需的訂單？

SELECT
       e_name,
       a_shortcut,
       GROUP_CONCAT(case
            when t_rank = 1 then  a_shortcut
            when t_rank = 2 then  a_shortcut
            when t_rank = 3 then  a_shortcut
            end separator ',') as group_con 
        FROM team 
        INNER JOIN event 
        ON team.EID = event.eid 
        WHERE e_type = 'nonsport'  
        GROUP BY event.eid ORDER BY t_rank

當我輸入t_rank時，此查詢始終為我提供隨機順序。 它不是給我1,2,3的命令，而是一直給我隨機的命令。 有人可以幫我嗎？

這是給我的結果

 {"nresults":[{"e_name":"Musical Festival - Song Composition","First":"2nd",
"Second":"1st",
"Third":"3rd"}]}

這是我的預期輸出

    {"nresults":[{"e_name":"Musical Festival - Song Composition","First":"1st",
"Second":"2nd",
"Third":"3rd"}]}

好吧，我現在開始工作了。 感謝大家。

 select
              e_name,
              a_shortcut,
              GROUP_CONCAT(case
                when t_rank = 1 then  a_shortcut
                when t_rank = 2 then  a_shortcut
                when t_rank = 3 then  a_shortcut
              end order by t_rank separator ',') as group_con 
            from
              team inner join event on team.EID = event.eid Where e_type = 'nonsport' 
group by event.eid

我只是將order by子句移到group_concat內部分隔符的末尾之后
