hibernate Criterias and Projections Using Projections
Example
Should we wish to retrieve only a few columns, we can use the Projections class to do so. For example, the following code retrieves the title column
// Selecting all title columns
List review = session.createCriteria(TravelReview.class)
.setProjection(Projections.property("title"))
.list();
// Getting row count
review = session.createCriteria(TravelReview.class)
.setProjection(Projections.rowCount())
.list();
// Fetching number of titles
review = session.createCriteria(TravelReview.class)
.setProjection(Projections.count("title"))
.list();
