named query in hibernate

Hibernate Named Queries Example
Using Named Query
named query example

Calling a named query
In Hibernate, the getNamedQuery() method obtains a Query instance for a named query:
session.getNamedQuery("findItemsByName")
.setString("desc", description);



Java
Persistence also supports named
queries:

em.createNamedQuery("
findItemsByName").setParameter("desc",
 description);

 


Named queries don't have to be HQL or JPA QL strings; they may even be native 
SQL queries—and your Java code doesn't
 need to know the difference:

<sql-query name="findItemsByName">
    <return alias="item"
 class="Item"/>
    <![CDATA[
        select {item.*} 
from item where name like :desc
    ]]>
</sql-query>



named query with annotations

Assume you consider 
a particular named query to belong to a particular entity class:

package auction.model

import ...;

@NamedQueries({
 
   @NamedQuery(
     name = "findItemsByName",
     query = "select i from Item i where i.name like :name"
    ),
    ...
})
@Entity
@Table(name = "ITEM")
public class Item { ... }
