TypedQuery 错误“未设置所有命名参数”。 JPA / Hibernate

Question

I'm trying to build and execute a dynamic query that looks like this:

String query = "SELECT e FROM Employee e WHERE (1=1) AND (UPPER(e.lastName) LIKE :lastName)";

final TypedQuery<Employee> dbQuery = entityManager.createQuery(query, Employee.class);
dbQuery.setParameter("lastName", "%" + value.toString().toUpperCase() + "%"));

But it fails with this error:

org.hibernate.QueryException: Not all named parameters have been set: [lastName]

Most interesting is that in debug mod i can see that dbQuery has a bind for "lastName" parameter and contains the specified value inside its "parameterRegistrations" field. So i have no idea.

Alternative with using positional parameters like dbQuery.setParameter(1, "%" + value.toString().toUpperCase() + "%")); is not my case, so pls lets do not discuss it.

This question is similar to mine but it's still unanswered.

Answer 1

Sorry guys. It was my inattention, A super strange and legacy code was there, which was creating a new instance of TypedQuery much later based on my query. but without parameters. I didn't expect it. That was the reason.
