PSQLException: ERROR: column "drink1_.id" must appear in GROUP BY clause or used in aggregate function
问题
I am writing a REST MVC web-application with Spring Boot, Hibernate, and PostgreSQL. I need to get the 6 most popular drinks out of all the carts I have. To do this, I first wrote a query in SQL:
SELECT drink_id, sum(count) as count
FROM cart_items
GROUP BY drink_id
ORDER BY 2 DESC
LIMIT 6
There is a result and this code worked well:
Since I am working with JPA-repositories, I decided to write the same query in HQL. I wrote the request, but I had to remove LIMIT for a while since I didn't know how to implement it in HQL.
@Query("select C.drink, sum(C.count) as count from CartItem C group by C.drink order by 2 DESC")
Page<Drink> getMostPopularDrinks(Pageable pageable);
Then I decided to write a method for the output to check what I got:
Service:
public PageDTO<DrinkDTO> findAllDrinks(int page, int pageSize) {
PageRequest pageRequest = PageRequest.of(page, pageSize);
Page<Drink> drinkList = cartItemRepository.getMostPopularDrinks(pageRequest);
return new PageDTO<>(drinkMapper.drinksToDrinksDTO(drinkList));
}
Controller:
@GetMapping("/drinks")
public PageDTO<DrinkDTO> getAllDrinks(@RequestParam(value = "page", defaultValue = "0") int page,
@RequestParam(value = "page_size", defaultValue = "2") int pageSize) {
return drinkService.findAllDrinks(page, pageSize);
}
CartItem Entity:
@Getter
@Setter
@Entity
@NoArgsConstructor
@Table(name = "cart_items")
public class CartItem {
// ... (other fields and annotations)
}
Drink Entity:
@Data
@Entity
@NoArgsConstructor
@Table(name = "drink")
@Inheritance(strategy = InheritanceType.JOINED)
public class Drink {
// ... (other fields and annotations)
}
But unfortunately, I got an error. The error message indicates that the column "drink1_.id" must appear in the GROUP BY clause or be used in an aggregate function. This issue seems to be related to the construction of your query in HQL.
Please note that the logs provided are not complete, and there might be more information that could help diagnose the issue. If you need further assistance, feel free to provide more details about the specific error you are facing, and I'll do my best to help.

**得分**: 0
你需要在查询和类投影中使用 `join` 来映射你的数据
仅获取 Id 和 count
```java
@Query("select new com.example.dto.DrinkDTO(dr.id, sum(ci.count)) from CartItem ci join ci.drink dr "
+ "group by dr.id order by sum(ci.count) DESC")
Page<DrinkDTO> getMostPopularDrinks(Pageable pageable);
投影类
class DrinkDTO {
private Integer drinkId;
private long count;
public DrinkDTO(Integer drinkId, long count) {
this.drinkId = drinkId;
this.count = count;
}
// getter, setter
}
获取带有 count 的 Drink 实体
@Query("select new com.example.dto.DrinkDTO(dr, sum(ci.count)) from CartItem ci join ci.drink dr "
+ "group by dr order by sum(ci.count) DESC")
Page<DrinkDTO> getMostPopularDrinks(Pageable pageable);
投影类
class DrinkDTO {
private Drink drink;
private long count;
public DrinkDTO(Drink drink, long count) {
this.drink = drink;
this.count = count;
}
//getter, setter
}
英文:
You need to use join in query and class projection to map your data
Fetch only Id and count
@Query("select new com.example.dto.DrinkDTO(dr.id, sum(ci.count)) from CartItem ci join ci.drink dr "
+ "group by dr.id order by sum(ci.count) DESC")
Page<DrinkDTO> getMostPopularDrinks(Pageable pageable);
Projection class
class DrinkDTO {
private Integer drinkId;
private long count;
public DrinkDTO(Integer drinkId, long count) {
this.drinkId = drinkId;
this.count = count;
}
// getter, setter
}
Fetch Drink enity with count
@Query("select new com.example.dto.DrinkDTO(dr, sum(ci.count)) from CartItem ci join ci.drink dr "
+ "group by dr order by sum(ci.count) DESC")
Page<DrinkDTO> getMostPopularDrinks(Pageable pageable);
Projection class
class DrinkDTO {
private Drink drink;
private long count;
public DrinkDTO(Drink drink, long count) {
this.drink = drink;
this.count = count;
}
//getter, setter
}

以下是翻译好的内容：
@Query("select C.drink.id, sum(C.count) as count from CartItem C group by C.drink order by 2 DESC")
List<Long> getMostPopularDrinksIds();
英文:
It is not important for me to get exactly drinks directly from the database, you can also drink ID. After receiving the ID, I can find them in the same database, so I slightly changed my request.
@Query("select C.drink.id, sum(C.count) as count from CartItem C group by C.drink order by 2 DESC")
List<Long> getMostPopularDrinksIds();
