[hibernate-users] is using @GeneratedValue annotation on non-id column possible ?

Hello, I would like to use a @ GeneratedValue annotations on a non-id column, is that possible? The annotation is also used on the id : @Id @GeneratedValue (generator="naid-uuid") @GenericGenerator(name="naid-uuid", strategy="com.netappsid.erp.UUIDGenerator") @Type(type="com.netappsid.datatypes.UUIDUserType") @AccessType(value="field") public Serializable getId() { return id; } This is the field I'd like to auto-increment. @Column(name = "identifier", insertable = false, updatable = false) @Generated(value=GenerationTime.INSERT) @GeneratedValue(strategy=GenerationType.IDENTITY) @AccessType(value="field") public Long getIdentifier() { return identifier; } In PostgreSQL this column will be an int8 instead of a bigserial. In SQL Server this column will be a numeric (19,0) without identity Thank you in advance, Ghislain
