Complete Hibernate 3.0 Tutorial

This tutorial provide step by step instructions on using Hibernate 3.0. Hibernate is popular open source object relational mapping tool for Java platform. It provides powerful, ultra-high performance object/relational persistence and query service for Java. Hibernate lets you develop persistent classes following common Java idiom - including association, inheritance, polymorphism, composition and the Java collections framework. The Hibernate Query Language, designed as a "minimal" object-oriented extension to SQL, provides an elegant bridge between the object and relational worlds. Hibernate also allows you to express queries using native SQL or Java-based Criteria and Example queries. Hibernate is now the most popular object/relational mapping solution for Java.

15. Hibernate Count Query
    In this section we will show you, how to use the Count Query. Hibernate supports multiple aggregate functions. when they are used in HQL queries, they return an aggregate value (such as sum, average, and count) calculated from property values of all objects satisfying other query criteria.
            
16. Hibernate Avg() Function (Aggregate Functions)
    In this section, we will show you, how to use the avg() function. Hibernate supports multiple aggregate functions. When they are used in HQL queries, they return an aggregate value ( such as avg(...), sum(...), min(...), max(...) , count(*), count(...), count(distinct ...), count(all...) ) calculated from property values of all objects satisfying other query criteria. 
           
17. Hibernate Max() Function (Aggregate Functions)
    In this section, we will show you, how to use the Max() function. Hibernate supports multiple aggregate functions.
       
18. Hibernate Min() Function (Aggregate Functions)
    In this section, we will show you, how to use the Min() function. Hibernate supports multiple aggregate functions.
           
19. HQL Where Clause Example
    Where Clause is used to limit the results returned from database. In this lesson you will learn how to use HQL Where Clause.
       
20. HQL Group By Clause Example
    Group by clause is used to return the aggregate values by grouping on returned component. In this lesson you will learn how to use HQL Group By Clause.
     
21. HQL Order By Example
    Order by clause is used to retrieve the data from database in the sorted order by any property of returned class or components. In this lesson you will learn how to use HQL Order By Clause.
      
     
    Hibernate Criteria Query
22. Hibernate Criteria Query Example
    In this lesson you will learn how to use Hibernate Criteria Query.
     
23. Narrowing the result set
    In this lesson you will learn how to use Hibernate Criteria Query to narrow down the result data.
      
24. Hibernate's Built-in criterion: Between (using Integer)
    In this tutorial,, you will learn to use "between" with the Integer class. "Between" when used with the Integer object, It takes three parameters e.g.  between("property_name",min_int,max_int).
    
25. Hibernate's Built-in criterion: Between (using Date)
    In this section, you will learn to use "between" i.e.one of the built-in hibernate criterions. Restriction  class  provides built-in criterion via static factory methods.
          

26. Hibernate Criteria Expression (eq)
    In this section, you will learn to use the "eq" method. This is one of the most important  method that is used to apply an "equal" constraint to the named property.
          

27. Hibernate Criteria Expression (lt)
    In this section, you will learn to use the "lt" method. This is one of the most important  method that is used to apply a "less than" constraint to the named property.
