hql query to retrieve data that has max date value - sql

Question

I'm using Spring Data JPA and I need to retrieve a set of data.
Entities I'm working with:
NationalPart
#Id #GeneratedValue(strategy=GenerationType.IDENTITY)
private Long idNationalPart;
private Date nationalPartStartDate;
#ManyToOne
#JoinColumn(name="idCategory")
private Category nationalCategory;
#ManyToOne
#JoinColumn(name="idInstitution")
private Institution nationalInstitution;
Institution
#Id #GeneratedValue(strategy=GenerationType.IDENTITY)
private Long idInstitution;
#Column(length=200)
#NotEmpty
#Size(min=3,max=200)
private String institutionName;
#OneToMany(mappedBy="nationalInstitution",fetch=FetchType.LAZY)
private Collection<NationalPart> nationalParts;
I have multiple NationalParts that contain the same Institution, but in each NationalPart, Institution is paired with a different Category. In order to show a specific Institution "inst1" details I need to retrieve the Category currently attached to it through NationalPart. The correct Category to show would be the most recent one, which means I need to retrieve the NationalPart that has the max value of nationalPartStartDate and "inst1" as its Institution.
This is what I did:
public interface NationalPartRepository extends JpaRepository<NationalPart, Long> {
#Query("select np1 from NationalPart np1 where np1.nationalInstitution.idInstitution =:x and np1.nationalPartStartDate = max(select np2.nationalPartStartDate from NationalPart np2 where np2.idNationalPart=np1.idNationalPart)")
public NationalPart getLatestNationalPart(#Param("x")Long idInstitution);}
However this doesn't work and I get the following exception:
com.microsoft.sqlserver.jdbc.SQLServerException: Cannot perform an aggregate function on an expression containing an aggregate or a subquery.

I'm a beginner when it comes to HQL/SQL so I really don't know what to + the query I came up with looks pretty messy and I'm sure there is a better way to retrieve the info I need~ Also should I use a join in my query?

Answer 1

#Query("select np1 from NationalPart np1 where np1.nationalInstitution.idInstitution =:x and np1.nationalPartStartDate = (select max(np2.nationalPartStartDate) from NationalPart np2 where np2.idNationalPart=np1.idNationalPart)")
