I’ve two tables. EMP and DEPTNO related collectively refrential Integrity contraint.
EMP.DEPTNO = DEPT.DEPTNO
I’ve to replace EMP.DEPTNO relying upon deptName entered by person. See question under.
replace emp set dept_no = (choose dept_no from dept the place dept_name = 'HR') the place emp_no = 3
I wish to do that utilizing JPA, Hibernate queries.
I’ve two entites
EMP @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(title = "dept_no", referencedColumnName = "dept_no") non-public Dept dept; DEPT
The adjustments to emp.dept_no isn’t taking place. CascadeType won’t assist as a result of I haven’t got to insert into dept desk. It is simply an replace to emp desk.
What am I lacking right here?
