Question

I’m trying to exclude a bunch of results from a database SELECT using the “NOT IN” keywords, but the exclusion list is still being returned. Using JPQL (JPA2.0) my query looks like:

Query query = em.createQuery("SELECT foo.id FROM FooEntity fooEntity WHERE foo.id NOT IN ('" + exclusionList.toString() + "') ORDER BY foo.id").setFirstResult(startPosition).setMaxResults(numberOfAppsToReturn);

exclusionList is a StringBuffer. There is no error reported that I can see, but the id’s in the exclusion list are still returned. Is there an alternative JPQL way of doing this?

Thanks in advance.

I think the mistake is in foo. What is foo you have to defined it any where.

Write FooEntity foo instead of FooEntity fooEntity
