java.sql.SQLException:检测到未定义的列名。（冬眠）

我有下面的方法，它给了我一个异常

private double doFullCalculation(Iterable<OfferToCatalog> startOfferCatalogs, Iterable<OfferToCatalog> endOfferCatalogs){
        double fullWeeksSales=0d;
        int startWeeks=0;
        int startIteration =0;
        for(OfferToCatalog startOfferToCatalog: startOfferCatalogs){
            List<OfferWeeks> startOfferWeeks = offerWeeksRepository.getWeeksForCatalogNumber(startOfferToCatalog.getOfferToCatalogKey().getBusinessUnitNumber()+""+startOfferToCatalog.getOfferToCatalogKey().getCatalogNumber()+""+startOfferToCatalog.getOfferToCatalogKey().getCatalogVersion());
            startIteration++;
            if(startIteration==1){
                startWeeks=startOfferWeeks.size();
            }
         fullWeeksSales += addStartWeeks(startWeeks, startOfferWeeks);   
        }
        for(OfferToCatalog endOfferToCatalog: endOfferCatalogs){    
            List<OfferWeeks> endOfferWeeks = offerWeeksRepository.getWeeksForCatalogNumber(endOfferToCatalog.getOfferToCatalogKey().getBusinessUnitNumber()+""+endOfferToCatalog.getOfferToCatalogKey().getCatalogNumber()+""+endOfferToCatalog.getOfferToCatalogKey().getCatalogVersion());
            fullWeeksSales += addEndWeeks(startWeeks, endOfferWeeks);   
        }
        return fullWeeksSales;   
    }

我能找出问题所在。在“传递”失败的方法时，这是查询返回数据的唯一时间。因为第二列是数据的总和，所以如果我没有声明，它就不会返回命名列

我的实体映射正在为第二列寻找一个命名列，但由于它在结果集中没有命名，我的程序不知道如何处理数据

@Entity
@Table(name = "OECATPAG")
public class OfferWeeks implements Serializable{
    String week;
    BigDecimal sales;

    @Id
    @Column(name = "FCLYERWK", columnDefinition = "varchar2(40)")
    public String getWeek() {
        return week;
    }

    public void setWeek(String week) {
        this.week = week;
    }

    @Column(name = "RMSALES", columnDefinition = "decimal(18,9)")
    public BigDecimal getSales() {
        return sales;
    }

    public void setSales(BigDecimal sales) {
        this.sales = sales;
    }

}

失败时，

：catalogNumber

的值是多少？您是否查看了IBM i服务器上连接会话的作业日志中的消息？服务器上有IBM i的哪个版本&TR#？当它失败时，：catalogNumber是“1202312A”。工作：catalogNumber为“1202830B”
