这是我的Hibernate Statment。它应该告诉我我的订单费用多少 或者我可以使用其他东西来获得成本吗？
public Query sum() {
Session session = NewHibernateUtil.getSessionFactory().getCurrentSession();
Transaction transaction = session.beginTransaction();
Query baum = session.createQuery("SELECT SUM(Anz_Normal*Preis_normal+Preis_family*Anz_family) from Bestellung,Pizza p,Kunde where p.Id = pizza and Email = 'a@f'");
transaction.commit();
return baum;
}
我在程序中运行它：
Query cost = bestellungRepository.sum();
jLabel3.setText(cost + " €");
这就是我得到的错误。我已经干了以使用createSQLQuery（）但这没有帮助。

有人能帮助我吗？+
这是我的披萨班：
package pizzahibernate.model;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class Pizza implements Serializable {
private static final long serialVersionUID = 6946049944294004465L;
@Id
private int id;
private String text;
@Column(name="NAME")
private String pName;
private float preis_normal;
private float preis_family;
public Pizza() {
}
public Pizza(final int Id, final String pName, final String Text,final float Preis_normal,final float Preis_family) {
this.preis_normal = Preis_normal;
this.preis_family = Preis_family;
this.id = Id;
this.text = Text;
this.pName = pName;
}
public int getId() {
return id;
}
public void setId(final int id) {
this.id = this.id;
}
public String getText() {
return text;
}
public void setText(final String Text) {
this.text = Text;
}
public String getpName() {
return pName;
}
public void setpName(final String pName) {
this.pName = pName;
}
public float getPreis_normal() {
return preis_normal;
}
public void setPreis_normal(final float Preis_normal) {
this.preis_normal = (int) Preis_normal;
}
public float getPreis_family() {
return preis_family;
}
public void setPreis_family(final float Preis_family) {
this.preis_family = (int) Preis_family;
}
}
如果我在Select查询中写了那个id，它就不会给出错误，但是我得到了输出：来自Bestellung，Pizza p，Kunde的QueryImpl（SELECT SUM（Anz_Normal Preis_normal + Preis_family Anz_family）其中p .id =披萨和电子邮件='a @ f'€
答案 0 :(得分：2)
在查询中应该 id 而不是 ID 。
Query baum = session.createQuery("SELECT SUM(Anz_Normal*Preis_normal+Preis_family*Anz_family) from Bestellung,Pizza p,Kunde where p.id = pizza and Email = 'a@f'"
