I am trying to query a table as follows
select * from client c
where EXISTS (select * from visit v where c._id = v.client_id)
Can i do this with ORMLITE?
Yes you can. Where.exists()
has been supported my ORMLite for some time. Here are the meager docs on exists .
You would do something like the following:
QueryBuilder<Visit, Integer> visitQb = visitDao.queryBuilder();
visitQb.where().eq(Visit.CLIENT_ID_FIELD, client.getId());
QueryBuilder<Client, Integer> clientQb = clientDao.queryBuilder();
clientQb.where().exists(visitQb);
List<Client> results = clientQb.query();
