HQL Select in Join语句

querydsl spring-data-jpa hibernate spring

我试图创建HQL查询,该查询与其他细节一起,也从其他表中选择聚合。预期结果如下:

member, collectionAmount, deductionAmount, saleAmount, prePaymentAmount
------------------------------------------------------------------------
<m>   ,    250          ,  550           ,   1500    ,    4550

        "SELECT ctJoin.totalCollection, stJoin.saleAmount, dtJoin.deductionAmount, pJoin.prePaymentAmount, mp.amount, mp.memberId " +
        "FROM MemberPayment mp " +
        "LEFT JOIN ( " +
            "SELECT SUM(ct.price * ct.quantity) AS totalCollection , ct.member.memberId AS memberId  " +
            "FROM CollectionTransaction ct " +
            "WHERE ct.paymentPeriod.paymentPeriodId = ?1 AND ct.voided = false " +
            "GROUP BY ct.member.memberId) AS ctJoin ON mp.memberId.memberId = ctJoin.memberId " +
        "LEFT JOIN ( " +
            "SELECT SUM(st.saleAmount) AS saleAmount, st.memberId.memberId AS memberId " +
            "FROM SaleTransaction st " +
            "WHERE st.paymentPeriod = ?1 AND st.voided = false " +
            "GROUP BY st.memberId.memberId) AS stJoin ON stJoin.memberId = mp.memberId.memberId "+
        "LEFT JOIN ( " +
            "SELECT SUM(dt.amount) AS deductionAmount, dt.memberId.memberId AS memberId " +
            "FROM DeductionTransaction dt " +
            "WHERE dt.paymentPeriod = ?1 AND dt.voided = false " +
            "GROUP BY dt.memberId.memberId ) AS dtJoin ON dtJoin.memberId = mp.memberId.memberId "+
        "LEFT JOIN ( " +
            "SELECT SUM(p.paymentTransaction.amount) AS prePaymentAmount, p.memberId.memberId AS memberId " +
            "FROM MemberPayment p " +
            "WHERE p.paymentPeriodId = ?1 AND p.voided = false AND p.paymentTransaction.paymentType.id = 7 " +
            "GROUP BY p.memberId.memberId ) AS pJoin ON pJoin.memberId = mp.memberId.memberId "+
        "WHERE mp.memberId.memberId IN (?2)"

Intellij在运行时抛出此错误:

问题

使现代化

会员支付模式

public class MemberPayment extends BaseEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "payment_id")
    private Integer paymentId;
    @JoinColumn(name = "member_id", referencedColumnName = "member_id")
    @ManyToOne(optional = false)
    private CoopMember memberId;

    @Column(name = "paymentperiod_id")
    private Integer paymentPeriodId;

    @JoinColumn(name = "payment_transaction")
    @OneToOne(cascade = CascadeType.ALL)
    private PaymentTransaction paymentTransaction;
}

CollectionTransaction , DeductionTransaction SaleTransaction 所有人都有一个

@JoinColumn(name = "member_id", referencedColumnName = "member_id")
@ManyToOne(optional = false)
private CoopMember memberId;

在没有看到模型的情况下,很难构建SQL语句。但我试过了)

select 
    m as member, 
    sum(ct.price * ct.quantity) as collectionAmount, 
    sum(dt.amount) as deductionAmount, 
    sum(st.saleAmount) as saleAmount, 
    sum(pt.amount) as prePaymentAmount
from 
    MemberPayment mp
    left join mp.collectionTransaction ct
    left join mp.saleTransaction st
    left join mp.deductionTransaction dt
    left join mp.paymentTransaction pt
    join pt.paymentType type
    join mp.memberId m
where
    ct.paymentPeriod = ?1 and ct.voided = false and 
    st.paymentPeriod = ?1 and st.voided = false and
    dt.paymentPeriod = ?1 and dt.voided = false and
    mp.paymentPeriod = ?1 and mp.voided = false and type.id = 7 and
    m.memberId in ?2
group by
    m

select 
    m as member, 
    sum(ct.price * ct.quantity) as collectionAmount, 
    sum(dt.amount) as deductionAmount, 
    sum(st.saleAmount) as saleAmount, 
    sum(pt.amount) as prePaymentAmount  
from 
    MemberPayment mp, CollectionTransaction ct, DeductionTransaction dt, SaleTransaction st
    join mp.memberId m
    join mp.paymentTransaction pt
where 
    mp.paymentPeriodId = ?1 and
    m.memberId in ?2 and 
    ct.memberId = m and ct.paymentPeriodId = mp.paymentPeriodId and
    dt.memberId = m and dt.paymentPeriodId = mp.paymentPeriodId and
    st.memberId = m and st.paymentPeriodId = mp.paymentPeriodId 
group by
    m
