Question

I am pretty new to Hibernate based Application Developing.
Recently i run the same code(which is shown in the below) in Eclipse Juno IDE. It works fine.
But when coming to Netbeans it doesn’t work.And it shows the error as

SEVERE: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘.users users0_ where users0_.uname=’username” at line 1

Here Iam using the Mysql 5.5,IDE-NetBeans-7.2.1.

Here the code i am executing is,

Hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

package hibernatefiles;
public class Users  implements java.io.Serializable {

}

I am Executing the HQL in the below JSP File by using Query Class.

<%@page import="hibernatefiles.Users"%>
<%@page import="java.util.Iterator"%>
<%@page import="org.hibernate.Query"%>
<%@page import="org.hibernate.Session"%>
<%@page import="org.hibernate.Transaction"%>
<%
    String user_id = request.getParameter("uid");
    String u_pass = request.getParameter("upass");
    out.println("got it dude we get the details..."+user_id+"\n"+u_pass);

    //writing the hibernate code

    Transaction transaction;

    Session ses = hibernatefiles.NewHibernateUtil.getSessionFactory().openSession();
    try{
             transaction = ses.beginTransaction();
             String HQL = "FROM Users u WHERE u.uname='"+user_id+"'";
             Query query = ses.createQuery(HQL);
            java.util.List li = query.list();
            Iterator itera = li.iterator();
            while(itera.hasNext()){
        //getting record
                Users u= (Users) itera.next();
        out.println("user name is:"+u.getUname());
                out.println("user password is :"+u.getUpass());         

            }

    }
    catch(Exception error){
        error.printStackTrace();

    }

Answer 1

The problem seems to be in the schema “OFFICE MANAGER”. It has blank space, so it needs to be quoted. Is really “OFFICE MANAGER” the right name? If it is right, then you have to change your hibernate mapping file, to quote the catalog attribute:

<class name="hibernatefiles.Users" table="users" catalog="`OFFICE MANAGER`">

However, I don’t know why it worked in Eclipse. If you are curious, you could try to run it again in eclipse with <property name="hibernate.show_sql">true</property> <property name="hibernate.format_sql">true</property> so that is shows the query.
