I am working with springboot, spring data jpa ,Oracle db. If i changed the schema i am getting this error, without schema change everything is working fine.
I am not using sequence
@Entity
@Table(name = "CLIENTS")
public class CLIENTS implements Serializable {
private static final long serialVersionUID = 123;
@Id
@Column(name = "ID")
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer clientId;
@Column(name = "CODE")
private Integer code;
@Column(name = "REC_ID")
private Integer recId;
//setters, getters, etc
}
"I am not using sequence". Sure you are. GenerationType.AUTO
has chosen it for you out of TABLE
, SEQUENCE
and IDENTITY
.
The sequence exists in the old schema, but if you change the schema you need to create the sequence in the new schema too.
Extend to Kayaman
Oracle @GeneratedValue(strategy = GenerationType.AUTO ) Spring data jpa (or) Hibernate will create a sequence itself and it is used for all insertions , that sequence name HIBERNATE_SEQUENCE , we have to create into new schema, if not exist
To know the all sequences
SQL>select * from user_sequences;
For Creating sequence
SQL> create sequence HIBERNATE_SEQUENCE
SQL>create sequence HIBERNATE_SEQUENCE
start with 1 increment by 1 maxvalue 9999999999999999999999999999 minvalue 1 cache 20;
FOR delete Sequence
SQL> drop sequence HIBERNATE_SEQUENCE;
