如何在Hibernate中的@Formula中编写复杂查询，或者在hibernate中将派生值发送到UI的最佳方法是什么？

我在方法中有这个查询但在@Formula下。基本上这个方法需要转换为ui中的派生列进行排序

如何在计算字段上对primefaces lazy数据表进行排序。

public Double getTaxAmount() {
        return new BigDecimal(getNetAmount() + (getNetAmount() * (taxRate != null ? taxRate.getRate() : 0))).setScale(2, RoundingMode.HALF_DOWN).doubleValue();
    }

我如何查询

@MappedSuperclass
public abstract class Bill extends IdentityEntity {


    @Column(name = "AMOUNT")
    @Setter
    private Double amount;


    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "TAX_ID")
    @Getter
    @Setter
    private TaxRate taxID;

    @Formula( "(SELECT
        invc.ID as ID,
        (invc.NET_NET_AMOUNT + ( invc.NET_NET_AMOUNT * ISNULL(tx.RATE,0) )) AS TAX_INCLUDED_AMOUNT
        FROM INVOICE invc
        left join TAX_RATE tx on invc.TAX_RATE_ID = tx.ORIGINAL_TAX_RATE_ID)")
    @Getter
    private Double totalAmount;

    public Double getNetAmount() {
        return amount;
    }

    public Double getTaxAmount() {
        return new BigDecimal(getNetAmount() + (getNetAmount() * (taxID != null ? taxID.getRate() : 0))).setScale(2, RoundingMode.HALF_DOWN).doubleValue();
    }
}

发票扩展了Bill，在UI上显示了Invoice。

    @Entity
    @Table(name = "INVOICE")
    @Audit(of = {"number"})
    public class Invoice extends Bill{

        @Column
        ...
    }

税率表

@Entity
@Table(name = "TAX_RATE")
public class TaxRate extends Name implements Serializable {

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

    @Column(name = "TAX_ID", insertable = false, updatable = false)
    @Getter
    @Setter
    private Long taxId;

    @Column(name = "RATE")
    @Getter
    @Setter
    private Double rate;

    }
到目前为止，我有：

  @Formula( "(SELECT
        invc.ID as ID,
        (invc.NET_NET_AMOUNT + ( invc.NET_NET_AMOUNT * ISNULL(tx.RATE,0) )) AS TAX_INCLUDED_AMOUNT
        FROM INVOICE invc
        left join TAX_RATE tx on invc.TAX_RATE_ID = tx.ORIGINAL_TAX_RATE_ID)")

但它不起作用。或者我可以用列名

写@Formula

(AMOUNT+(AMOUNT* ISNULL(TAXRATE.RATE,0)))。这样的事情。

<p:column styleClass="amountColumn" sortBy="#{item.totalAmount}">
...
</p:column>

所以当我打电话点击排序。它给出了一个错误：

  invoice0_.PURCHASE_ORDER_NUMBER 
as PURCHASE_ORDER_NUMBER103_143_, invoice0_.REMARK as REMARK104_143_, invoice0_.SENT as SENT105_143_,

我对Hibernate相当新，我不明白我做错了什么？为什么不允许子查询？有一些我不知道的东西。请帮忙。

编辑：即使我提出此查询，它也会抛出相同的错误。

@Formula("(select sum(oe.NET_NET_AMOUNT) from INVOICE oe where oe.ID = ID)")

1 个答案:

答案 0 :(得分：0)

select sum(oe.amount,(oe.amount* isnull(oe.taxrate,0))) from order oe

Order是一个SQL保留字，只需更改您的表名，不会抛出此异常

java.sql.SQLException: Subqueries are not allowed in an ORDER BY clause.
