我在一个SQL查询中需要两个子查询 其中一个结果可能是' 1,3,2'另一个是' 1,2,3' 我怎么能判断这两个结果是平等的 我真的需要他们是平等的......
两个子查询是sql
SELECT t.project_id,GROUP_CONCAT(t.type,',') AS seg_type FROM
t_project_bid_announce_draft t WHERE t.project_id = '6639124947eb4e0cafc054b9ddcf9f54'
和sql
SELECT p.segment_type FROM t_project_segment p WHERE p.project_id =
'6639124947eb4e0cafc054b9ddcf9f54'
答案 0 :(得分:0)
使用order by
:
SELECT t.project_id,
GROUP_CONCAT(t.type ORDER BY t.type SEPARATOR ',' ) AS seg_type
FROM t_project_bid_announce_draft t
WHERE t.project_id = '6639124947eb4e0cafc054b9ddcf9f54'
