Summary: I am unable to use columns with names identical to function names in projections. Context: Given I have an entity with a column called `sign`:
@Entity
@Table(name = "test")
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
public class TestEntity{
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "task_id", nullable = false, updatable = false)
private UUID taskId;
@Column(name = "title", nullable = false)
private boolean sign;
}
With a pojo defined that I want to project into:
public class TestProjection {
private boolean title;
public TestProjection(boolean title){
this.title = title;
}
}
Now, defining and running the following jpql query
public interface TestRepository extends JpaRepository<TestEntity, UUID> {
@Query(
"""
select new some.entity.TestProjection(
t.sign
)
from TestEntity t
"""
)
List<TestProjection> getAll();
}
leads to an exception
org.springframework.dao.InvalidDataAccessApiUsageException: org.springframework.data.jpa.repository.query.BadJpqlGrammarException: Line 2:10 no viable alternative at input 't.sign'; Bad JPQL grammar [ select new some.entity.TestProjection(
t.sign
)
from TestEntity t

I would expect it to resolve `t.sign` to be the `sign` property of the `TestEntity` what I think is what really happens is that `sign` is resolved to be the `sign()` function (i.e. `sign(-10) = -1`). A similar exception occurs, when the column gets renamed to other popular function names such as `log` or `exp`. Renaming the column to `signing` leads to the query working as expected. |
