Java 一对多关系的HQL是“给予”；ORA-00936：缺少表达式；例外

我有两个具有一对多关系的表，如下所示：

select a.auditId, a.startTime, a.endTime, a.auditParameterDataSet from AuditDetail a;

我的实体类和hbm配置如下所示：

select a.auditId, a.startTime, a.endTime, a.auditParameterDataSet from AuditDetail a;

AuditDetail.java

public class AuditDetail implements Serializable {

    private static final long serialVersionUID = 1L;
    private String auditId;
    private Timestamp startTime;
    private Timestamp endTime;
    Set auditParameterDataSet;

    public Set getAuditParameterDataSet() {
        return auditParameterDataSet;
    }
    public void setAuditParameterDataSet(Set auditParameterDataSet) {
        this.auditParameterDataSet = auditParameterDataSet;
    }
    public String getAuditId() {
        return auditId;
    }
    public void setAuditId(String auditId) {
        this.auditId = auditId;
    }
    public void setStartTime(Timestamp startTime) {
        this.startTime = startTime;
    }
    public Timestamp getEndTime() {
        return  endTime;        
    }
    public void setEndTime(Timestamp endTime) {
        this.endTime = endTime;
    }   
}

public class AuditParameter {

    private String auditId ;
    private String parameterId;
    private String fieldName ;
    private AuditDetail auditDetail;

    public String getAuditId() {
        return auditId;
    }
    public void setAuditId(String auditId) {
        this.auditId = auditId;
    }
    public String getParameterId() {
        return parameterId;
    }
    public void setParameterId(String parameterId) {
        this.parameterId = parameterId;
    }
    public String getFieldName() {
        return fieldName;
    }
    public void setFieldName(String fieldName) {
        this.fieldName = fieldName;
    }
    public AuditDetail auditDetail() {
        return auditDetail;
    }
    public void setAuditDetail(AuditDetail auditDetail) {
        this.auditDetail = auditDetail;
    }

}

        </property>


    </class>
</hibernate-mapping>

但当我执行此查询时，它会给我以下错误：

ORA-00936：缺少表达式

下面是我的控制台输出的查询

select au0_.AUDITID as col_0_0_, au0_.STARTTIME as col_1_0_, au0_.ENDTIME as col_2_0_, . as col_3_0_ 
from AUDITDETAIL au0_ inner join AUDITPARAMETER auditparam4_ on au0_.AUDITID=auditparam4_.AUDITID

根据这个输出，我们可以看到hibernate没有为a.auditParameterDataSet生成列名。为什么会这样？我哪里做错了？

您必须使用：-

HQL：-

标准：-

Criteria criteria = session.createCriteria(AuditDetail.class);
criteria.setFetchMode("auditParameterDataSet", FetchMode.EAGER);

谢谢你的回答，加入解决了我的问题。我所做的唯一更改是在查询中将.auditParameterDataSet替换为auditParameterDataSet，并从查询中删除fetch，因为它会给我带来错误，如：查询指定的联接提取，但提取关联的所有者不在选择列表中。请参考并更新您的答案。顺便说一句，从我的结束+1解决我的问题。
