Doing an “IN” query with Hibernate

Question

I have a list of IDs in a String, and want to use Hibernate to get the rows with these IDs. TrackedItem is a Hibernate/JPA entity (sorry if I\'m getting the nam

Answer 1

The syntax of your JPQL query is incorrect. Either use (with a positional parameter):

List ids = Arrays.asList(380L, 382L, 386L);
Query query = em.createQuery("FROM TrackedItem item WHERE item.id IN (?1)");
query.setParameterList(1, ids)
List items = query.getResultList();

Or (with a named parameter):

List ids = Arrays.asList(380L, 382L, 386L);
Query query = em.createQuery("FROM TrackedItem item WHERE item.id IN :ids");
query.setParameterList("ids", ids)
List items = query.getResultList();

Below, the relevant sections of the JPA 1.0 specification about parameters:

4.6.4.1 Positional Parameters

The following rules apply to positional parameters.

• Input parameters are designated by the question mark (?) prefix followed by an integer. For example: ?1.
• Input parameters are numbered starting from 1.
  Note that the same parameter can be used more than once in the query string and that the ordering of the use of parameters within the query string need not conform to the order of the positional parameters.

4.6.4.2 Named Parameters

A named parameter is an identifier that is prefixed by the ":" symbol. It follows the rules for identifiers defined in Section 4.4.1. Named parameters are case sensitive.

Example:

SELECT c
FROM Customer c
WHERE c.status = :stat

Section 3.6.1 describes the API for the binding of named query parameters
