sql - I need to pass column names using variable in select statement in Store Procedure but i cannot use dynamic query

Here is my SQL query below. I want to select values from the column names given as variables. Is there any appropriate way of doing this except using a dynamic query?

SELECT EPV.EmployeeCode, @RateOfEmployee, @RateOfEmployer
FROM [HR_EmployeeProvisions] EPV

One way to do this without using dynamic sql is using CASE statement

But this is ugly

SELECT EPV.EmployeeCode, case @RateOfEmployee  when 'RateOfEmployee' then RateOfEmployee
when 'X' then X 
..
end , case @RateOfEmployer  when 'RateOfEmployer' then RateOfEmployer
when 'Y' then Y
..
end 
FROM [HR_EmployeeProvisions] EPV

You have to check all the column's in CASE statement.
