Suppose we have two classes A and B: Class A:
public class A {private Long id;}
Class B:
public class B {private Long id; private String name ; private Boolean isDeleted = false; }
Is there a way to have results of Join query with some other conditions besides the condition ON I tried this but I doesn't work, the compiler doesn't recognize clause ON org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token
:
@Query( "SELECT new com.demo.DTO.resultsDTO(a.id) FROM A ate , B a ON a.id = b.id WHERE b.isDeleted = false AND b.name = ?1 ")
I tried also to include the a.id = b.id in the clause WHERE, but it doesn't return results. Please help.
Your query is off, and is mixing the old-school implicit join syntax with the modern (preferred) join syntax. Here is the version you should be using:
SELECT new com.demo.DTO.resultsDTO(a.id)
FROM A a
INNER JOIN B b
ON a.id = b.id
WHERE
b.isDeleted = false AND
b.name = ?1;
Your updated Java code:
@Query("SELECT new com.demo.DTO.resultsDTO(a.id) FROM A a INNER JOIN B b ON a.id = b.id WHERE b.isDeleted = false AND b.name = ?1")
