Question

我正在尝试使用Criteria构建一个复杂的查询。我在SQL中创建了查询，以便向您解释我想要的内容：

SELECT ID, DATE
FROM SELLS v
WHERE DATE > (SELECT min(DATE)
            FROM SELLS
            WHERE CODE IN (12345, 12344)
            AND ID = v.ID)
AND DATE>TO_DATE('2015-01-01', 'YYYY-MM-DD')
AND DATE<TO_DATE('2016-01-01', 'YYYY-MM-DD')
GROUP BY ID, DATE

这是我的班级：

@Entity
@Table(name = "SELLS")
@Getter
public class Sells {

    @Id
    @Column(name = "SELL_ID")
    private Integer idSell;

    @Column(name = "ID")
    private Integer id;

    @Column(name = "DATE")
    private Date date;

    @Column(name = "CODE")
    private String code;
}

我在Criteria中尝试的内容（开始和结束是WHERE中的两个日期（'2015-01-01'和'2016-01-01'）：

    Criteria c = getSession().createCriteria(Sells.class);

    List subquery = getSession().createCriteria(Sells.class)
            .add(Restrictions.in("code", {"12345", "12344"}))
            .createAlias("Sells.id", "id")
            .setProjection(Projections.projectionList()
                    .add(Projections.min("date")))
            .list();

    c.add(Restrictions.ge("date", subquery));
    c.add(Restrictions.ge("date", start));
    c.add(Restrictions.le("date", end));
    c.setProjection(Projections.projectionList()
            .add(Projections.groupProperty("date"))
            .add(Projections.groupProperty("id")));

我也尝试使用DetachedCriteria但失败了。

DetachedCriteria query = DetachedCriteria.forClass(Sells.class, "v");
DetachedCriteria subquery = DetachedCriteria.forClass(Sells.class, "bv")
    .add(Restrictions.in("bv.code", codes))
    .add(Restrictions.eq("bv.id", "v.id")
    .setProjection(Projections.projectionList()
        .add(Projections.min("bv.date")));


query.add(Restrictions.ge("v.date", subquery))
    .add(Restrictions.ge("v.date", start))
    .add(Restrictions.le("v.date", end))
    .setProjection(Projections.projectionList()
        .add(Projections.groupProperty("v.date"))
        .add(Projections.groupProperty("v.id")));

如果有人知道如何做到这一点会对我有所帮助！

编辑：这看起来更好但仍无效：

Criteria query = getSession().createCriteria(Sells.class, "v");
DetachedCriteria subquery = DetachedCriteria.forClass(Sells.class, "bv")
    .add(Restrictions.in("bv.code", codes))
    .add(Restrictions.eq("bv.id", "v.id")
    .setProjection(Projections.projectionList()
        .add(Projections.min("bv.date")));


query.add(Restrictions.ge("v.date", subquery))
    .add(Restrictions.ge("v.date", start))
    .add(Restrictions.le("v.date", end))
    .setProjection(Projections.projectionList()
        .add(Projections.groupProperty("v.date"))
        .add(Projections.groupProperty("v.id")));

org.hibernate.criterion.DetachedCriteria无法强制转换为java.util.Date

使用Criteria查询子查询
