【问题描述】：

我正在尝试对特定日期执行聚合操作。请在下面找到相同的查询。

@Modifying
@Query("SELECT new AggregateJourneyFoodOrder(mealRetrievalTime, SUM(head_count), SUM(bread), SUM(achar), SUM(jam) ,SUM(others), SUM(puri), SUM(roti), SUM(thepla))"
        + "  FROM JourneyFoodOrder WHERE isRemoved=false AND mealRetrievalTime = :mealRetrievalDate")
List<AggregateJourneyFoodOrder> getOrdersByDateAndNotDisabled(Boolean isRemoved, Date mealRetrievalDate);

我遇到了例外情况

AggregateJourneyFoodOrder.java

public class AggregateJourneyFoodOrder 
    private int totalHeadCount;
    private int totalBread;
    private int totalAchar;
    private int totalJam;
    private int totalOthers;
    private int totalPuri;
    private int totalRoti;
    private int totalThepla;
    private Date mealRetrievalDate;
    //Getter Setters and Constructors

JourneyFoodOrder.java

@Entity
public class JourneyFoodOrder
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long orderId;
        
    private Integer headCount;
        
    @DateTimeFormat(pattern = "dd/MM/yyyy")
    private Date dateOfOrderPlaced;
        
    @DateTimeFormat(pattern = "dd/MM/yyyy")
    private Date dateOfDeparture;
        
    @DateTimeFormat(pattern = "dd/MM/yyyy h:mm a")
    private Date mealRetrievalTime;
    
    @ManyToOne
    private UserEntity user; 
        
    private Integer thepla;
        
    private Integer puri;
        
    private Integer roti;
    
    private Integer achar;
        
    private Integer jam;
        
    private Integer bread;
        
    private Integer others;
        
    private Boolean isRemoved;
    //Getters and setters

我不明白我到底做错了什么。还建议是否查询如何对特定日期执行聚合操作。

【参考方案1】：

我认为这与聚合函数没有任何关系，但与您尝试将 LIKE 运算符（和通配符修饰符 %）应用于 Date 类型的参数无关，这不起作用。

由于我不确定该构造应该意味着什么，因此我真的不能推荐其他替代方法：使用 String 或不同的比较运算符，例如 = 或 >=。

注意：@Modifying 注释似乎是错误的，因为此查询是纯选择查询，应该按原样执行。

【讨论】：

“似乎不起作用”究竟是什么意思？

我将查询更改为 - ` @Modifying @Query("SELECT new AggregateJourneyFoodOrder(SUM(head_count), SUM(bread), SUM(achar), SUM(jam) ,SUM(others), SUM (puri), SUM(roti), SUM(thepla))" + " FROM JourneyFoodOrder WHERE isRemoved=false AND mealRetrievalTime = :mealRetrievalDate") List getOrdersByDateAndNotDisabled(@Param("mealRetrievalDate")Date mealRetrievalDate);` 但它不要改变我得到的错误。

@Andronicus 请让我知道我在这里做错了什么。我是 Spring Data JPA 的新手，正在努力从中获得结果。
