Hibernate interview questions

!!! Hibernate interview questions !!!

addScalar() method in hibernate...




Double max = (Double) sess.createSQLQuery("select max(cat.weight) as maxWeight from cats cat")
.addScalar("maxWeight", Hibernate.DOUBLE);
.uniqueResult();

addScalar() method confim that maxWeight is always double type.

This way you don't need to check for it is double or not.
