@Query is returning error when I pass more than one object in the select query.
Error - Validation failed for query for method public abstract java.util.List
Pojo
@Entity
@Table(name = "SUBJECT")
public class Subject {
private long id;
private Long fkCode;
private Long fkData;
private Date assignedDate;
private Data data;
private Code code;
//setters getters
@OneToOne
@JoinColumn(name="fkCode",insertable=false, updatable=false)
public Code getCode() {
return code;
}
@OneToOne
@JoinColumn(name="fkData",insertable=false, updatable=false)
public Data getData() {
return data;
}
public Subject(long id, Long fkEquipment, Long fkCode,Date assignedDate, Long fkData,Data data,Code code) {
super();
this.id = id;
this.fkCode = fkCode;
this.fkData = fkData;
this.assignedDate = assignedDate;
this.data = data;
this.code=code;
}
In my repository
@Query(" select new Subject(id, fkCode, fkData, assignedDate, data, code)"
+ " from Subject a where trunc(a.assignedDate) = TO_DATE(?1, 'yyyy-mm-dd') "
+ " order by a.id desc")
List<Subject> findByAssignedDate(String assignedDate);
Here is the error

if I remove either code or data from the query it works..
@Query(" select new Subject(id, fkCode, fkData, assignedDate, data)" - working
@Query(" select new Subject(id, fkCode, fkData, assignedDate, code)" - working
@Query(" select new Subject(id, fkCode, fkData, assignedDate, data, code)" not working
not working together. Need you help/suggestions
