  What you can do is if the parameter is null set it to equal itself. If you pass a parameter it will use the value otherwise it will ignore it.

  SELECT Emp_No,Emp_Name,Emp_Surname

  FROM Employees

  WHERE Emp_Name LIKE ISNULL(@Emp_Name + '%', Emp_Name) AND

  Emp_Surname LIKE ISNULL(@Emp_Surname + '%', Emp_Surname)
