I am working on website for classified ads using spring 3.1 and hibernate 3.6. I have four entities (User, UserRole, Advertisement and Category). I am using a separate dao for each class. All the operations in Daos for User and UserRoles work fine. But in the daos for Advertisement and Category, save/update throws an SQLGrammarException.
Advertisement Class
@Entity
@Table(name="ads")
public class Advertisement implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue
@Column(name = "AD_ID")
private String adId;
@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name="CAT_ID" )
private Category category;
@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name="USER_ID" )
private User user;
@Column(name = "TITLE")
private String title;
@Column(name = "DESC", nullable = true)
private String desc;
@Column(name = "PRICE")
private double price;
@Column(name ="IMG1" , nullable = true)
private String imageOne;
@Column(name ="IMG2" , nullable = true)
private String imageTwo;
@Column(name ="IMG3" , nullable = true)
private String imageThree;
@Temporal(TemporalType.TIMESTAMP)
@Column(name ="CREATED")
private Date createdOn;
//Getters and setters
}
Category Class
@Entity
@Table(name="cats")
public class Category implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue
@Column(name = "CAT_ID")
private String catId;
@Column(name = "CAT_NAME", unique=true)
private String catName;
@Column(name ="DESC" , nullable = true)
private String desc;
@OneToMany(mappedBy="category", fetch=FetchType.LAZY)
private List<Advertisement> allAds;
//getters and setters
}
AdvertisementDao
@Repository
@Transactional
public class AdvertisementDaoImpl implements AdvertisementDao {
private HibernateTemplate hibernateTemplate;
@Autowired
public void setSessionFactory(SessionFactory sessionFactory)
{
this.hibernateTemplate = new HibernateTemplate(sessionFactory);
}
@Override
public void save(Advertisement ad)
{
hibernateTemplate.save(ad);
}
@Override
public void update(Advertisement ad) {
hibernateTemplate.update(ad);
}
@Override
public void delete(Advertisement ad) {
hibernateTemplate.delete(ad);
}
@Override
public Advertisement getAdById(String adId) {
Advertisement ad = (Advertisement) hibernateTemplate.get(Advertisement.class, adId);
return ad;
}
@SuppressWarnings("unchecked")
@Override
public List<Advertisement> getAdsByUserId(String userId) {
String sql = "SELECT * FROM ads USER_ID = :uID";
List <Advertisement> adList= new ArrayList<Advertisement>();
Query qry = hibernateTemplate.getSessionFactory().getCurrentSession().
createSQLQuery(sql)
.addEntity(Advertisement.class)
.setParameter("uID", userId);
adList = ( List <Advertisement> ) qry.list();
return adList;
}
}

I tried removing the ManytoOne associations (removing USER_ID and CAT_ID FKs), but I cannot save to these two tables. But I can get an object of Advertisement class by calling advertisementDao.getAdById(id), it also loads relevent Category object and User object automatically. I have also added all the four classes to hibernate config file.
I can’t see what gives this error. Finally I tried to create a SQL Insert query in the traditional way by getting Query object from session. It also give this same error. Please help me. Thank you
DESCis a reserved word in MySQL, so you can’t use it for a column name. You should rename you column for the insertion to work.
