Make hibernate ignore class variables that are not mapped

Question

I thought hibernate takes into consideration only class variables that are annotated with  Column   But strangely today when I added a variable  that is not mapped to any column  just a variable i need in the class   it is trying to include that variable in the select statement as a column name and throws the error -      Unknown column  team1  agencyName  in  field list    My class -    Entity  Table name  team   public class Team extends BaseObject implements Serializable     Id   GeneratedValue strategy GenerationType AUTO  private Long id    Column length 50  private String name    Column length 10  private String code    Column name    agency id   private Long agencyId   private String agencyName    note  not annotated       FYI   I use the above class in another class with many to many mapping   ManyToMany fetch   FetchType EAGER    JoinTable          name  user team           joinColumns      JoinColumn  name  user id              inverseJoinColumns    JoinColumn  name  team id         public Set lt Team gt  getTeams         return teams      Why is this happening

For folks who find this posting through the search engines  another possible cause of this problem is from importing the wrong package version of  Transient   Make sure that you import javax persistence transient and not some other package

Placing  Transient on getter with private field worked for me   private String name        Transient     public String getName             return name             public void setName String name            this name   name

JPA will use all properties of the class  unless you specifically mark them with  Transient    Transient private String agencyName    The  Column annotation is purely optional  and is there to let you override the auto-generated column name  Furthermore  the length attribute of  Column  is only used when auto-generating table definitions  it has no effect on the runtime
