休眠-（）之间的限制

Question

 Criteria cr=session.createCriteria(Student.class).add(Restrictions.between("strStudentMark1", "90", "100"));

In the above code snippet, I have given the mark between 90 and 100. In the Student table, there are fields between marks 90 and 100. but am not getting those in the output.

What could be the problem? Am I making any mistake?

EDIT

Yes am getting the whole list when I run.

Criteria cr=session.createCriteria(Student.class);

Student entity is below with generated Getters and Setters.

import java.io.Serializable;

public class Student implements Serializable {

private String strStudentID;
private String strStudentRegNO;
private String strStudentName;
private String strStudentMark1;
private String strStudentMark2;
private String strStudentDegree;
private String strStudentMobileNO;
private String strStudentMailID;
private String strSalary;


public String getStrSalary() {
    return strSalary;

    this.strSalary = strSalary;

    return strStudentID;

Answer 1

Please make sure that the data stored in the Database is an INT. The between will only work with INT Datatype. Also try passing the value as int in code.
