Problem with Hql Update

[Sujoy Mukherjee]

hi,
I am very new to hibernate. I am trying my hands on HQL. I am trying Updating a table but facing a problem. I will try to explain it in as much detail I can.
First of all I am using netbeans 7.2, Oracle 10G express edition.

(1)The Table called book and its like this:

create table book
(
bookid varchar2(10) primary key,
bookname varchar2(50),
bookprice number(5)
)

(2)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">
<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
    <property name="hibernate.connection.driver_class">oracle.jdbc.OracleDriver</property>
    <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:XE</property>
    <property name="hibernate.connection.username">hr</property>
    <property name="hibernate.connection.password">hr</property>
    <property name="hibernate.show_sql">true</property>
    <property name="hibernate.current_session_context_class">thread</property>
    <property name="hibernate.query.factory_class">org.hibernate.hql.ast.ASTQueryTranslatorFactory</property>
    <property name="hibernate.hbm2ddl.auto">update</property>
    <mapping resource="code/Book.hbm.xml"/>
  </session-factory>
</hibernate-configuration>

(3)hibernate.reveng.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd">
<hibernate-reverse-engineering>
  <schema-selection match-schema="HR"/>
  <table-filter match-name="BOOK"/>
</hibernate-reverse-engineering>

(4)book.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- Generated Jan 21, 2013 10:01:49 PM by Hibernate Tools 3.2.1.GA -->
<hibernate-mapping>
    <class name="code.Book" table="BOOK" schema="HR">
        <id name="bookid" type="string">
            <column name="BOOKID" length="10" />
            <generator class="assigned" />
        </id>
        <property name="bookname" type="string">

        </property>
        <property name="bookprice" type="java.lang.Integer">
            <column name="BOOKPRICE" precision="5" scale="0" />
        </property>
    </class>
</hibernate-mapping>

(5)The POJO class, book.java

package code;
// Generated Jan 21, 2013 10:01:48 PM by Hibernate Tools 3.2.1.GA



/**
 * Book generated by hbm2java
 */
public class Book  implements java.io.Serializable {


     private String bookid;
     private String bookname;
     private Integer bookprice;

    public Book() {
    }

	
    public Book(String bookid) {
        this.bookid = bookid;
    }
    public Book(String bookid, String bookname, Integer bookprice) {
       this.bookid = bookid;
       this.bookname = bookname;
       this.bookprice = bookprice;
    }
   
    public String getBookid() {
        return this.bookid;
    }
    
    public void setBookid(String bookid) {
        this.bookid = bookid;
    }
    public String getBookname() {
        return this.bookname;
    }
    
    public void setBookname(String bookname) {
        this.bookname = bookname;
    }
    public Integer getBookprice() {
        return this.bookprice;
    }
    
    public void setBookprice(Integer bookprice) {
        this.bookprice = bookprice;
    }

@Override
    public String toString() {
        return "Book {" + "bookId= " + bookid + " "+"bookName= " + bookname + " "+"bookPrice=" + bookprice + " "+'}';
    }

   

}

(6)And finally, HQLUpdate.java, where the problem occurs

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
package code;

import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import util.NewHibernateUtil;
/**
 *
 * @author Sujoy
 */
public class HQLUpdate {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
         Transaction tx = null;
        Book b = new Book();
         SessionFactory sf = NewHibernateUtil.getSessionFactory();
        Session s=sf.openSession();
        tx = s.beginTransaction();
        String hql = "update book set bookname :bname where bookid :bid";
        Query query = s.createQuery(hql);
        query.setParameter("bname", "The C Programming Language");
query.setParameter("bid", "");
int result = query.executeUpdate();
        System.out.println("Rows affected: "+result);
        /*List results = query.list();
        System.out.println("Results: "+results);*/
    }
}

[Sujoy Mukherjee]

When I am executing HQLUpdate.java, the following Exception message comes:
Exception in thread "main" org.hibernate.hql.ast.QuerySyntaxException: expecting EQ, found ':' near line 1, column 26 [update book set bookname :bname where bookid :bid]

The full output looks like this:

Can you please tell me where is the problem?
Thanks in advance.

[Salil Vverma]

The problem is with HQL you are using. You are using below query -

update book set bookname :bname where bookid :bid

while it should be as mentioned below (= operator is missing in your query) -

update book set bookname = :bname where bookid :bid

Kindly try it and let us know if you are still facing any issues

[Emanuel Kadziela]

I think the last post is still missing a "=", try this ...

update book set bookname = :bname where bookid = :bid

[Salil Vverma]

Hey Emanuel,

Good catch..
The correct hql would be -

update book set bookname = :bname where bookid = :bid  

[Sujoy Mukherjee]

Extremely sorry for replying so late. Thanks to both Salil and Emanuel for replying.
I tried your solution....but an exception is thrown now.
it is saying....Exception in thread "main" org.hibernate.hql.ast.QuerySyntaxException: book is not mapped [update book set bookname =:bname where bookid =:bid]
