I have the following criteria please advise how can I convert the below criteria into HQL , as I want to use HQL
public List<tttBook> findtooks() {
List<tttBook> tooks =null;
Criteria criteria = session.createCriteria(tttBook.class);
ProjectionList proList = Projections.projectionList();
proList.add(Projections.property("Id"));
proList.add(Projections.property("longName"));
tooks = criteria.list();
return tooks;
}
also please let me know in this above criteria what is wrong since right now it is fetching all the attributes of the object and it takes lots of time i think there is something wrong with my projections implementation.
You can create another constructor in your object tttBook
. Also you should follow naming convention and call class starting with capital letter and properties with small letter.
package yourpath;
public class TttBook {
private Long id;
private String longName;
public TttBook(Long id, String longName) {
this.id = id;
this.longName = longName;
}
// getters, setters
}
Query
List<TttBook > list = (List<TttBook >) session.createQuery("select
new yourpath.TttBook(id, longName) from TttBook").list();
