Difference between name and referencedColumnName in @JoinColumn annotation?

Question

@ManyToOne
@JoinColumn(name = "someValue" , referencedColumnName = "someOtherValue" )

what values are to be placed in name and r

Answer 1

Suppose you have Two tables:

1. Department table with columns:
 a. Dept_ID (primary key)
 b. Dept_Name

2. Employee Table with following column:
  a. Emp_Id (primary key)
  b. Dept_Id_fk (foreign key)
  c. Salary

Now your join column for Employee Entity class will be

@ManyToOne
@JoinColumn(name = "Dept_Id_fk", referencedColumnName = "Dept_ID")
Department department;

So referencedColumnName means column that you are referencing to from your foreign key column.
