org.hibernate.exception.GenericJDBCException: could not execute statement in hibernate

Question

I am trying to use embeddable annotation to store different values in one object to be persisted in one table.

I have two classes: userDetails:

package org.hibernet.src;
@Entity
@Table (name="UserDetails")
 public class userDetails {
 @Id 
@GeneratedValue(strategy = GenerationType.AUTO)
private int userId;
@Temporal(TemporalType.DATE)
private Date dob;
public Date getDob() {
    return dob;
}
public void setDob(Date dob) {
    this.dob = dob;
}
private String userName;
@Embedded
private Address address;

public Address getAddress() {
    return address;
}
public void setAddress(Address address) {
    this.address = address;
}
public int getUserId() {
    return userId;
}
public void setUserId(int userId) {
    this.userId = userId;
}
public String getUserName() {
    return userName;
}
public void setUserName(String userName) {
    this.userName = userName;
}

}

2. Address class which is embeddable class:

    @Embeddable
   
    public class Address {
   
   @Column(nullable=true)
   private String street;
   
   @Column(nullable=true)
   private String city;
   
    @Column(nullable=true)
    private String state;
   
   
   public String getStreet() {
   return street;
   }
   public void setStreet(String street) {
   this.street = street;
   }
   public String getCity() {
       return city;
   }
    public void setCity(String city) {
       this.city = city;
    }
   public String getState() {
   return state;
   }
   public void setState(String state) {
       this.state = state;
   }
   

   } this is my main class:

   public static void main(String[] args) {
   
   userDetails user = new userDetails();
   Address add = new Address();
   
   user.setUserName("Dipesh");
   user.setDob(new Time(0));
   add.setCity("vadodara");
   add.setState("gujarat");
   add.setStreet("raopura");
   
   
   
   SessionFactory sessionfactory = new     
    Configuration().configure().buildSessionFactory();
   Session session = sessionfactory.openSession();
   session.beginTransaction();
   session.save(user);
   session.save(add);
   /*user = (userDetails)session.get(userDetails.class, 6);*/
   
   session.getTransaction().commit();
   session.close();
   

   }

I was trying to store the data but it was showing:

   ERROR: Field 'pincode' doesn't have a default value

I had pincode in my address but it was showing an error so i removed it but still it showing that error.

Please help me to solve it.

Answer 1

The table in your db has a field pincode for which you've not defined a default value and is not nullable. However, your entity has no mapping for that field and you are not sending a value for this field. Thus, java.sql.SQLException: Field 'pincode' doesn't have a default
value
