Sorry, really new to JPA.|
I have an Embedded ID class used as the primary key. How do I select data only using one of the fields in the key??
I have two fields in the EmployeePK: (emp_grp, hire_date). emp_grp and hire_date would be a unique record. I want to select all records with emp_grp.
I can do this: "select m from Employee m where m.id = 'id'"
But the id field is the EmployeePK class and I must also use the hire_date.
I want something like this: select m from Employee m where m.emp_grp = "emp_grp"
but the "m.emp_grp" field is not visible since its in the EmployeePK class.
