Question

I am using Oracle as backend and when i try to insert any entry the sequence which hibernate is generating is of the order of “50010255” but in my db the current value of SEQ_AD_WORK sequence shows only “1000221” i am unable to figure out how that can happen.

following are my configurations

   <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.query.startup_check">false</prop>
            <!-- 
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            -->
        </props>
    </property>`

   @Id
@Column(name = "ITEM_ID", unique = true, nullable = false,  scale = 0)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQ_AD_WORK")
 @SequenceGenerator(name="SEQ_AD_WORK", sequenceName="SEQ_AD_WORK")
public Long getAdWorkItemId() {
    return this.adWorkItemId;
}

@Dhirendra: try this:-

@SequenceGenerator(name=”SEQ_AD_WORK”,sequenceName=”SEQ_AD_WORK”,,allocationSize=1)

SequenceHiLoGenerator is the default sequence generator for JPA and the default allocationSize value of 50,
