Is it possible to have autoincrement number without it being an ID?

Question

I keep googling and find that the only way is to use

@Id
@GeneratedValue(strategy = GenerationType.Identity)

But I already have a primary key,

Answer 1

Perhaps you can try:

@GeneratedValue(GenerationType.strategy=SEQUENCE, generator="internal_seq")
@SequenceGenerator(name="internal_seq", sequenceName="internal_seq", allocationSize=1)
@Column(name="internalID")
public Long internalID;
