Question

我有3个具有HQL类的表的查询。有一对一的关系。

我的数据库或每个实体类没有问题..

我有一些类hibernate DAO查询，除了这个之外一切都很好..

用于jasperreport的类reportserviceimpl，

我得到了这样的错误

线程中的异常“AWT-EventQueue-0”org.hibernate.hql.ast.QuerySyntaxException：意外的令牌：ase靠近第1行，第84列[选择s.product.name作为productName，sum（s.quantity）as quantity，s.sales.noTable ase noTable，s.sales.member as member，s.price as price，sum（s.subtotal）as subTotal from restodeskapp.model.SalesDetail s其中s.sales.id =：id group by s.product.name order by s.product.name] 在org.hibernate.hql.ast.QuerySyntaxException.convert（QuerySyntaxException.java:31）在org.hibernate.hql.ast.QuerySyntaxException.convert（QuerySyntaxException.java:24）在org.hibernate.hql.ast.ErrorCounter.throwQueryException（ErrorCounter.java:59）在org.hibernate.hql.ast.QueryTranslatorImpl.parse（QueryTranslatorImpl.java:258）在org.hibernate.hql.ast.QueryTranslatorImpl.doCompile（QueryTranslatorImpl.java:157）在org.hibernate.hql.ast.QueryTranslatorImpl.compile（QueryTranslatorImpl.java:111）在org.hibernate.engine.query.HQLQueryPlan。（HQLQueryPlan.java:77）在org.hibernate.engine.query.HQLQueryPlan。（HQLQueryPlan.java:56）

这里是我的HBL代码

List<SalesReport> salesReports =
        sessionFactory.getCurrentSession()
        .createQuery("select s.product.name as productName,"
        + " sum(s.quantity) as quantity,"
        + " s.sales.noTable as noTable,"
        + " s.sales.member as member,"
        + " s.price as price,"
        + " sum(s.subtotal) as subTotal from SalesDetail s "
        + " where s.sales.id = :id "
        + " group by s.product.name order by s.product.name")
        .setParameter("id", id)
        .setResultTransformer(
        Transformers.aliasToBean(SalesReport.class))
        .list();

这是我的SalesReport

public class SalesReport {
    private String productName;
    private String member;
    private int noTable;
    private Long quantity;
    private BigDecimal subTotal;
    private BigDecimal price;
//setter getter
}

这是我的销售

public class Sales implements Serializable{

    @Id @GeneratedValue
    @Column(name="ID")
    private Long id;

    @Column(name="NO_TABLE", nullable=false)
    private int noTable;

    @Temporal(TemporalType.TIMESTAMP)
    @Column(name="SALES_DATE",nullable=false)
    private Date salesDate;

    @OneToMany(mappedBy="sales",cascade=CascadeType.ALL)
    @Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
    private List<SalesDetail> salesDetails;

    @Column(name="TOTAL_SALES",precision=18,scale=0,nullable=false)
    private BigDecimal totalSales;

    @ManyToOne
    @JoinColumn(name="Member_ID")
    private Member member;
//setter getter
}

这里是我的salesdetail

public class SalesDetail implements Serializable{

    @Id @GeneratedValue
    @Column(name="ID")
    private Long id;

    @ManyToOne
    @JoinColumn(name="PRODUCT_ID",nullable=false)
    private Product product;

    @Column(name="QUANTITY",nullable=false)
    private Integer quantity;

    @Column(name="PRICE",nullable=false,precision=18,scale=0)
    private BigDecimal price;

    @Column(name="SUBTOTAL",nullable=false,precision=18,scale=0)
    private BigDecimal subtotal = BigDecimal.ZERO;

    @ManyToOne
    @JoinColumn(name="SALES_ID",nullable=false)
    private Sales sales;
}

这是我的产品

public class Product implements Serializable {

    @Id @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="ID")
    private Long id;
    @Column(name="NAME",unique=true,length=200)
    private String name;
    @Column(name="DESCRIPTION",unique=false,length=500)
    private String description;
    @Column(name="PRICE",unique=false,length=200)
    private BigDecimal harga;
    @Column(name="note",unique=false,length=500)
    private String note;
    @Enumerated(EnumType.STRING)
    @Column(name="STATUS",length=20)
    private EnumStatus status;
    @Enumerated(EnumType.STRING)
    @Column(name="TYPE",length=20)
    private EnumJenisMakanan type;
    @Lob
    @Column(name="PICTURE")
    private byte[] picture;

}

我真的不知道那是错的.. 请帮忙..

谢谢你...... 最好的考虑:)）

Answer 1

您的例外情况显示为unexpected token: ase near line 1, column 84，错误进一步显示您已在此处使用 - ＆gt; s.sales.noTable ase noTable

因此，查找ase，您的HBL代码没有此错误。我会说，搜索你的代码库并尝试找出你在其他地方指定了这个拼写错误s.sales.noTable ase noTable。您修复s.sales.noTable ase noTable - ＆gt; s.sales.noTable as noTable错误应该消失。

你有可能修复它但仍面临同样的错误。在这种情况下，尝试清理缓存，删除工作＆amp;临时文件夹并重复构建和部署。

查看问题是否消失。

Answer 2

    + " s.sales.noTable ase noTable,"

代码ase中有一个拼写错误，不应该是as吗？
