java - hibernate 异常: unexpected token: HAVING

标签 java mysql spring hibernate rest

我必须通过比较给定的距离输入(即纬度和经度)来从数据库中整理结果。冲浪后，我在 SQL 中找到了解决方案，并将其转换为相应的 HQL。

我的查询是:

SELECT restaurantId,restaurantName,address1,((ACOS(SIN(9.9986 * PI() / 180) * SIN(latitude * PI() / 180) + COS(9.9986 * PI() / 180) * COS(latitude * PI() / 180) * COS((76.3125-longitude) * PI() / 180)) * 180 / PI()) * 60 * 1.1515) AS distanceInKm FROM Restaurants HAVING distanceInKm<=1 ORDER BY distanceInKm ASC

这会出现错误Hibernate Exception:意外 token :HAVING。 请注意，在此 distanceInKm 中是一个虚拟列。我还需要将虚拟列添加到响应中。我尝试使用 where 而不是 having 但它显示未知列距离InKm

方法 

public List<Restaurants> getRestaurantsByDistance(FilterMovieRequest filterMovieRequest) throws SQLException, ClassNotFoundException, IOException {
        Session session = sessionFactory.getCurrentSession();
        String sql = "SELECT restaurantId,restaurantName,address1,((ACOS(SIN(9.9986 * PI() / 180) * SIN(latitude * PI() / 180) + COS(9.9986 * PI() / 180) * COS(latitude * PI() / 180) * COS((76.3125-longitude) * PI() / 180)) * 180 / PI()) * 60 * 1.1515) AS distanceInKm FROM Restaurants HAVING distanceInKm<=1 ORDER BY distanceInKm ASC";
        Query query = session.createQuery(sql);
        List<Restaurants> rows = query.list();
        return rows;
    }

实体

@Entity
@Table(name = "restaurants")
public class Restaurants implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "restaurant_id")
    private int restaurantId;

    @Column(name = "restaurant_name")
    private String restaurantName;

    @Column(name = "category_id")
    private Integer categoryId;

    @Column(name = "image_url")
    private String imageUrl;

    private Float longitude;

    private Float latitude;

    @Column(name = "contact_name")
    private String contactName;

    @Column(name = "primary_phone")
    private String primaryPhone;

    @Column(name = "secondary_phone")
    private String secondaryPhone;

    private String fax;

    private String address1;

    private String address2;

//Getters and setters
}

我找到了与此相关的标签，但它不足以解决我的问题。

最佳答案

在 hibernate 中，您只能将 HAVING 子句与 GROUP BY 一起使用。如果您必须使用 HAVING，我更喜欢使用 createSQLQuery 如下。 

public List<Restaurants> getRestaurantsByDistance(FilterMovieRequest filterMovieRequest) throws SQLException, ClassNotFoundException, IOException {
            Session session = sessionFactory.getCurrentSession();
            Float latitude = Float.parseFloat(filterMovieRequest.Latitude() );//Get your latitude from request
            Float longitude = Float.parseFloat(filterMovieRequest.Longitude());//Get your longitude from request
            String sql = "SELECT restaurant_id,restaurant_name,category_id,image_url,longitude,latitude,contact_name,primary_phone,secondary_phone,fax,address1,address2,((ACOS(SIN(:lat * PI() / 180) * SIN(latitude * PI() / 180) + COS(:lat * PI() / 180) * COS(latitude * PI() / 180) * COS((:lon-longitude) * PI() / 180)) * 180 / PI()) * 60 * 1.1515) AS `distanceInKm` FROM `restaurants` HAVING `distanceInKm`<=1 ORDER BY `distanceInKm` ASC";
            Query query = session.createSQLQuery(sql).addEntity(Restaurants.class);
            query.setParameter("lat", latitude);
            query.setParameter("lon", longitude);
            List<Restaurants> restaurantses = query.list();
            return restaurantses;
        }

Entity

@Entity
@Table(name = "restaurants")
public class Restaurants implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "restaurant_id")
    private int restaurantId;

    @Column(name = "restaurant_name")
    private String restaurantName;

    @Column(name = "category_id")
    private Integer categoryId;

    @Column(name = "image_url")
    private String imageUrl;

    private Float longitude;

    private Float latitude;

    @Column(name = "contact_name")
    private String contactName;

    @Column(name = "primary_phone")
    private String primaryPhone;

    @Column(name = "secondary_phone")
    private String secondaryPhone;

    private String fax;

    private String address1;

    private String address2;

    @Column(insertable = false, updatable = false)
    private String distanceInKm; /*Virtual column for user responds*/

}

注意:如果您想将虚拟列(即 distanceInKm)传递给用户，您应该仅使用 Getter 方法。应设置条件@Column(insertable = false, updatable = false)
