Hibernate Return integer value
34,770
Solution 1
Use the uniqueResult() method in Query. see here for an example or read the api here.
Here is an example. Replace the place holders as need to use them.
sessionFactory = getHibernateTemplate().getSessionFactory();
Session session = sessionFactory.getCurrentSession();
Query query = session
.createQuery("select value from table where ...");
query.setParameters("param1", value1);
result = (Type) query.uniqueResult();
Solution 2
You could do something like:
String sql = "select count(*) from table where ...";
BigDecimal count = (BigDecimal) hibernateTemplate.execute(
new HibernateCallback() {
public Object doInHibernate(Session session) throws HibernateException {
SQLQuery query = session.createSQLQuery(sql);
return (BigDecimal) query.uniqueResult();
}});
return count;
