Hibernate Built-in criterion "between" Date
In this tutorial you will learn about how to use the built-in criterion ' between ' with the Date.
Hibernate provides the facility to make a Criteria query restricted. An interface Criterion is responsible for representing a query criterion as an object oriented this query might be used in a Criteria query to make it restricted. However, this interface may be implemented in the class where a custom restriction criteria is to be defined. A class Restrictions is a factory class that provides the built-in criterion.
Example :
Here I am going to give an example of built-in criterion "between" which is provided by the Restrictions factory class. Between criterion applied the between constraint on the specified properties i.e it returns the value between the specified minimum and maximum range. In this example I will fetch the id, name, gender of Employee2 from the table employeename2 between the specified date.
Table employeename2
CREATE TABLE `employeename2` ( `id` int(10) NOT NULL, `name` varchar(15) default NULL, `gender` varchar(5) default NULL, `age` int(10) default '0', `dateOfBirth` date default NULL, PRIMARY KEY (`id`) )
Employee2.java
package roseindia;
import java.util.Date;
public class Employee2 {
private int id;
private String name;
private String gender;
private int age;
private Date dateOfBirth;
public Employee2()
{
}
public Employee2(String name, String gender, int age, Date dateOfBirth)
{
this.name = name;
this.gender = gender;
this.age = age;
this.dateOfBirth = dateOfBirth;
}
public int getId()
{
return id;
}
public void setId(int id)
{
this.id = id;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
public String getGender()
{
return gender;
}
public void setGender(String gender)
{
this.gender = gender;
}
public int getAge()
{
return age;
}
public void setAge(int age)
{
this.age = age;
}
public Date getDateOfBirth()
{
return dateOfBirth;
}
public void setDateOfBirth(Date dateOfBirth)
{
this.dateOfBirth = dateOfBirth;
}
}

Output :

When you will execute the java file HibernateBetweenDateExample.java ( RightClick -> Run As -> Java Application ) a query and output will be displayed on your console as :
