JPA + @ManytoOne unidirection foreign key parent key not found
Hi Team,
I have two table one is master table and second table is reference table
table 1 - create new row in this table this will generate new sequence no lets say : r_id
table 2 - it has few row and we need to update row in this table with r_id
Class Table1
@SequenceGenerator(name="SEQ_MAP_GEN",sequenceName="SEQ_id", allocationSize=1,initialValue=1)
public class Table1 implements Serializable{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQ_MAP_GEN")
@Column(name="R_ID")
private Long rId;
---------
Class Table2
@ManyToOne(fetch=Fe-tchType.LAZY)
@JoinColumn(name = "R_ID")
private Table1 table1;
problem :
when i insert into table1 : it will generate new sequence and i need to update same in to table2. but i got below error...
