Question: What do you mean by Named - SQL query?

Answer: Named SQL queries are defined in the mapping xml document and called wherever required.
Example:
<sql-query name = "empdetails">
<return alias="emp" class="com.test.Employee"/>
SELECT emp.EMP_ID AS {emp.empid}, emp.EMP_ADDRESS AS {emp.address}, emp.EMP_NAME AS {emp.name} FROM Employee EMP WHERE emp.NAME LIKE :name
</sql-query>

Invoke Named Query :
List people = session.getNamedQuery("empdetails") .setString("TomBrady", name) .setMaxResults(50) .list();
