    Hi All,
    I am using sql plus. whenever i am creating primary key with @generatedValue and @SequenceGenerator annotations .. it is not creating the sequence numbers... instead it creates
    random number like generation type.AUTO.. can anybody tell why it is happening?

    Hi,
    thanks for replying..

    The data type is Integer..

    and the exact syntax i've written is,
    @Id
    @GeneratedValue(strategy=GenerationType.SEQUENCE,g enerator="xyz")
    @SequenceGenerator(initialValue=1,allocationSize=1 , name = "xyz", sequenceName="xyz")
    private int id;

    It should generate the sequence like 1,2,3... But actually it is creating the random numbers like 32,0,273,52,401..
    But my friends are telling that it will work fine with mySql .. But for sql plus it is not working...
