Can you please help me how to convert the following codes to using "in" operator of criteria builder? I need to filter by using list/array of usernames using "in".
I also tried to search using JPA CriteriaBuilder - "in" method but cannot find good result. So I would really appreciate also if you can give me reference URLs for this topic. Thanks.
Here is my codes:
//usersList is a list of User that I need to put inside IN operator
CriteriaBuilder builder = getJpaTemplate().getEntityManagerFactory().getCriteriaBuilder();
CriteriaQuery<ScheduleRequest> criteria = builder.createQuery(ScheduleRequest.class);
Root<ScheduleRequest> scheduleRequest = criteria.from(ScheduleRequest.class);
criteria = criteria.select(scheduleRequest);
List<Predicate> params = new ArrayList<Predicate>();
List<ParameterExpression<String>> usersIdsParamList = new ArrayList<ParameterExpression<String>>();
for (int i = 0; i < usersList.size(); i++) {
ParameterExpression<String> usersIdsParam = builder.parameter(String.class);
params.add(builder.equal(scheduleRequest.get("createdBy"), usersIdsParam) );
usersIdsParamList.add(usersIdsParam);
}
criteria = criteria.where(params.toArray(new Predicate[0]));
TypedQuery<ScheduleRequest> query = getJpaTemplate().getEntityManagerFactory().createEntityManager().createQuery(criteria);
for (int i = 0; i < usersList.size(); i++) {
query.setParameter(usersIdsParamList.get(i), usersList.get(i).getUsername());
}
List<ScheduleRequest> scheduleRequestList = query.getResultList();
The internal Query String is converted to below, so I don't get the records created by the two users, because it is using "AND".
select generatedAlias0 from ScheduleRequest as generatedAlias0 where ( generatedAlias0.createdBy=:param0 )
and ( generatedAlias0.createdBy=:param1 ) order by generatedAlias0.trackingId asc
Please need your advise. Thank you in advance.
