java.sql.SQLException: An undefined column name was detected. (Hibernate)

Question

I have the following method that is giving me a an exception.

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;   
    }

I only seem to get an error in the second for loop (the portion that gets endOfferWeeks). It's calling the exact same method as in the startOfferWeeks for loop, but I get the following exception:

I've looked at other posts for this issue, but this one seems to be different because the query seems to run fine the first time(s) it's executed. It's only in the second section of this method that I'm having an issue. I've looked to see what's being passed in as a parameter, and the query runs fine when I use DB Visualizer.

This is what my repository looks like if that's useful.

public interface OfferWeeksRepository extends CrudRepository<OfferWeeks, String>, 
        JpaRepository<OfferWeeks, String>, JpaSpecificationExecutor<OfferWeeks> {
     @Query(value="select a.FCLYERWK, cast(sum(a.RMSALES) as decimal(18,5)) " +
            "from DWALCTNFL as a " +
            "inner join ( " +
            "select b.ITMNBR, b.CATPFX " +
            "from OECATPAG b " +
            "where (b.PAGNBR >= 0 and b.PAGNBR < 600) AND " +
            "(b.PHOSIZ+b.TXTSIZ+b.WHTSPCSIZ) > 0 AND " + 
            "Rtrim(CAST(b.BUSUNTNBR as varchar(5)))||Rtrim(b.CATNBR)||Rtrim(b.CATVER)  = :catalogNumber " +
            "group by b.itmnbr, b.catpfx ) as c " +
            "on (a.ITMNBR=c.ITMNBR and a.ITMPFX=c.CATPFX) " +
            "where trim(a.ITMCATNBR) = :catalogNumber " +
            "group by a.FCLYERWK " +
            "order by a.FCLYERWK ", nativeQuery=true)
     List<OfferWeeks> getWeeksForCatalogNumber(@Param("catalogNumber") String catalogNumber);
}

What I expect to be getting from the query is this:

Answer 1

I was able to figure out what the issue was. On the "pass" through the method where it failed, that was the only time the query returned data. Since the 2nd column was a summation of the data, it wasn't returning a named column without me declaring it as such.

My entity mapping was looking for a named column for the second column, but since it wasn't named in the result set my program didn't know what to do with the data.

@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;
    }

}
