查询删除重复记录

Question

我有一个像

这样的查询

SELECT
  SM.*
FROM sorted_stop_master AS SM
INNER JOIN route_master AS RM
  ON SM.station_code = RM.station_code
WHERE RM.route_code = '102D'
AND SM.COMPANY_CODE = '0103'
ORDER BY CAST(RM.sequence_no AS int);

这会返回数据，但它包含重复记录。我想删除具有相同查询的重复行..

请帮我编辑查询..我尝试了一些修改，但没有成功。

试试这个？

SELECT DISTINCT SM.* 
FROM sorted_stop_master AS SM 
  INNER JOIN route_master AS RM ON SM.station_code = RM.station_code 
where RM.route_code= "102D" 
  AND SM.COMPANY_CODE='0103' 
ORDER BY CAST(RM.sequence_no as INT);
