如何我可以将以下SQL查询转换为HQL查询

Question

我有以下查询。如何将以下查询转换为HQL查询。

+--------+------------+-------+ 
| type | variety | price | 
+--------+------------+-------+ 
| apple | gala  | 2.79 | 
| apple | fuji  | 0.24 | 
| apple | limbertwig | 2.87 | 
| orange | valencia | 3.59 | 
| orange | navel  | 9.36 | 
| pear | bradford | 6.05 | 
| pear | bartlett | 2.14 | 
| cherry | bing  | 2.55 | 
| cherry | chelan  | 6.33 | 
+--------+------------+-------+ 

我希望得到以下结果

+--------+----------+-------+ 
| type | variety | price | 
+--------+----------+-------+ 
| apple | fuji  | 0.24 | 
| orange | valencia | 3.59 | 
| pear | bartlett | 2.14 | 
| cherry | bing  | 2.55 | 
+--------+----------+-------+ 

select f.type, f.variety, f.price 
from (
    select type, min(price) as minprice 
    from fruits group by type 
) as x inner join fruits as f on f.type = x.type and f.price = x.minprice; 

Answer 1

我认为这应该工作（未测试）：

select f.type, f.variety, f.price 
from fruits f 
where f.price = (
    select min(f2.price) 
    from fruits f2 
    where f2.type = f.type 
) 

编辑：请记住，如果type有同一个price多于一个variety，比所有这些行将被选中与此查询。
