内容图文

我有这个查询,效果很好.我使用MIN(home_price)显示作为起始价格,我使用此查询为api和WHERE子句添加到它,所以如果我按价格搜索MIN(home_price)更改.

SELECT MIN(home_price) as min_home_price,
   id,
   name,
   community,
   maplocation,
   locationLabel,
   logo 
FROM ourCommunity 
INNER JOIN readyBuilt 
   ON community = home_community 
INNER JOIN rb_locations 
   ON readyBuilt.home_location = rb_locations.locationId 
WHERE id IN ( SELECT DISTINCT id 
                 FROM ourCommunity 
                 INNER JOIN readyBuilt 
                        ON community = home_community 
                 WHERE isDeleted = 0 AND is_upcoming = 0) 
   AND home_status = 1 
 GROUP BY id,name,community,mapLocation,locationLabel,logo 
 ORDER BY name

所以我的解决方案是使用子查询

SELECT id,
   name,
   community,
   maplocation,
   locationLabel,
   logo, 
   (SELECT MIN(home_price) as min_home_price 
          FROM ourCommunity 
          INNER JOIN readyBuilt 
                 ON community = home_community 
          INNER JOIN rb_locations 
                 ON readyBuilt.home_location = rb_locations.locationId 
          WHERE id IN ( SELECT DISTINCT id 
                        FROM ourCommunity 
                        INNER JOIN readyBuilt 
                               ON community = home_community 
                        WHERE isDeleted = 0 
                               AND is_upcoming = 0) 
                 AND home_status = 1 
          GROUP BY id,name,community,mapLocation,locationLabel,logo 
          ORDER BY name) as org_min_home_price 
FROM ourCommunity 
INNER JOIN readyBuilt 
   ON community = home_community 
INNER JOIN rb_locations 
   ON readyBuilt.home_location = rb_locations.locationId 
WHERE id IN ( SELECT DISTINCT id 
                 FROM ourCommunity 
                 INNER JOIN readyBuilt 
                        ON community = home_community 
                 WHERE isDeleted = 0 AND is_upcoming = 0) 
   AND home_status = 1 
 GROUP BY id,name,community,mapLocation,locationLabel,logo 
 ORDER BY name

但是当我执行第二个查询时,我收到此错误

Subquery returns more than 1 row

当我删除GROUP BY时,MIN(home_price)没有错误,每行都是相同的.有没有人对如何完成我想要完成的事情有任何建议？

解决方法:

通常情况下,如果您将价格作为过滤器添加,则返回的最低价格将不是表格的实际最小值.

您可以加入由社区分组的每个min(home_price)的结果集

SELECT min_home_price,   
   id,
   name,
   community,
   maplocation,
   locationLabel,
   logo 
FROM ourCommunity
INNER JOIN (select min(home_price) min_home_price, home_community from readyBuilt group by home_community) b on b.home_community = community
INNER JOIN readyBuilt a ON community = a.home_community 
INNER JOIN rb_locations ON a.home_location = rb_locations.locationId 
WHERE id IN ( SELECT DISTINCT id 
                 FROM ourCommunity 
                 INNER JOIN readyBuilt ON community = home_community 
                 WHERE isDeleted = 0) 
AND home_status = 1 
GROUP BY id,name,community,mapLocation,locationLabel,logo 
ORDER BY name;
