Hi,
Thanks for the prompt answer. As I have explained that there is no PK in that table but as I must have to declare one Column as an @ID to get it deployed.
But now the problem is the PK is not getting inserted.

Any help on this is appreciated.

Thanks,
Tanujit

PK value assigned to the object is ignored if  @GeneratedValue(strategy = GenerationType.IDENTITY) is specified.

Hi,
I have a table which does not have PrimaryKey. But I have to declare a column as PK by this annotations:
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "UserKeyfield")

When I am performing an INSERT in this table using JPQL I am getting exception as null value can not be inserted into database for the column "UserKeyfield". I have checked that my Java object representing that table is having that PK value but while inserting it is just not getting inserted. May be because it is defined as "@GeneratedValue(strategy = GenerationType.IDENTITY)".

Is there any workaround to explicitely add the PK value while inserting the object into database?
