MySQL - 如果表A是左連接到表B，那麼我如何在表B中的字段ORDER BY？

Question

這是我的SQL查詢：

SELECT pts.pts_id, 
      pts.pts_name, 
      meds.* 
    FROM pts 
      LEFT JOIN meds 
      ON pts.pts_id = meds.pts_id_fk 
    WHERE pts.id_fk = $id 
     AND pts_current = 1 

表pts（即表A）具有以下數據：

pts_id time 
1  Joe 
2  Jack 
3  Jill 

表meds（即表B）具有以下數據：

pts_id_fk time 
1   7AM 
1   8AM 
1   9AM 
2   7AM 
2   10AM 
3   11AM 

我想ORDER BY該查詢結果基於time。

任何建議如何做到這一點？

Answer 1

SELECT pts.pts_id, 
      pts.pts_name, 
      meds.* 
    FROM pts 
      LEFT JOIN meds 
      ON pts.pts_id = meds.pts_id_fk 
    WHERE pts.id_fk = $id 
     AND pts_current = 1 

ORDER BY pts.pts_id, meds.time 

Answer 2

嚴正約ORDER BY meds.time
