Question

I am not seeing anymore where i am doing my mistake. Working with Spring 3 and Hibernate and Mysql so far worked perfectly and was ok, but on this one it just doesn’t work.

This is my class:

@Entity
@Table(name = "order")
@XmlRootElement(name = "order")
public class Order implements java.io.Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "idOrder", length = 11)
    private int id;

    @Column(name = "latitude", nullable = true, length = 45)
    private String latitude;

    @Column(name = "longitude", nullable = true, length = 45)
    private String longitude;

    @Column(name = "orderDate", length = 30)
    @DateTimeFormat
    private Date orderDate;

    @Column(name = "city", nullable = true, length = 45)
    private String city;

    @Column(name = "country", nullable = true, length = 45)
    private String country;

    @Column(name = "street", nullable = true, length = 45)
    private String street;

    @Column(name = "streetNo", nullable = true, length = 45)
    private String streetNo;

    @Column(name = "created", length = 30)
    @DateTimeFormat
    private Date created;

    @JoinColumn(name = "idTaxi")
    @JoinTable(name= "taxi")
    @Column(name = "idTaxi", length = 11)
    private Integer idTaxi;

    @Column(name = "orderstatus", nullable = false, length = 45)
    private String orderstatus;

    @Column(name = "clientname", nullable = true, length = 45)
    private String clientName;

    //public getters and setters

}

In db, my table name is “order”. I have checked all fields for typo.
In persistence xml config file:

[...]
 <property name="annotatedClasses">
     <list>
           <value>test.bean.Taxi</value> 
           <value>test.bean.Order</value>
     </list>
</property>
<property name="hibernateProperties">
    <props>
        <prop key="hibernate.dialect">
            org.hibernate.dialect.MySQLDialect
        </prop>
        <prop key="hibernate.hbm2ddl.auto">create</prop>
        <prop key="lazy">true</prop>
        <prop key="hibernate.show_sql">true</prop>
        <!-- Show and print nice SQL on stdout -->  
        <prop key="hibernate.format_sql">true</prop>
        <prop key="hibernate.archive.autodetection">class</prop>
    </props>
</property>
</bean>
[...]

In DAO class:

public List<Order> showAllOpenOrders() {

    List<Order> history = new ArrayList<Order>();
    history = getHibernateTemplate().find("FROM Order o where o.orderstatus ='open'");

    return history;
}

My Error:

I have successfully mapped another class(Taxi), but this one..just doesn’t work.I don’t get why… Do you see something i don’t?
So my db table is lowecase “order” and in my Class Order i am mapping that table.
But if I try to access all the records from database with status set on “open” like this:

public List<Order> showAllOpenOrders() {
    ;
    List<Order> history = new ArrayList<Order>();
    history = getHibernateTemplate().find("FROM Order o where o.orderstatus ='" + TaxiStatus.OPEN + "'");

    return history;
}

I receive an error that there is an SQL Exception.

Thank you for your time.

Answer 1

order – is reserved keyword in MySQL, and must be backquoted if it used not as part of order by

rewrite you query as:

history = getHibernateTemplate().find("FROM `Order` o where o.orderstatus ='" + TaxiStatus.OPEN + "'");
