mysql - MySQL-如果将表A左联接到表B，我如何对表B中的字段进行排序？

这是我的SQL查询：

    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）具有以下数据：

pts_id   time
1        Joe
2        Jack
3        Jill

表meds（即表B）具有以下数据：

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

我想ORDER BY基于time的查询结果。

有什么建议怎么做？

最佳答案

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
