I have to write a single query or stored procedure or function which can display all tables data using ASP.Net WEB API.
Please help me to to find solution. 
 
public class StudentController : ApiController
    {
         EmployeeDbEntities1 entities=new EmployeeDbEntities1();
       
        public IEnumerable<Students> Get()
        {
            List<Students> ListStud = new List<Students>();
            var query = (from a in entities.tblstudents
                         select a).ToList();
            query.ForEach(s =>
            {
            ListStud.Add(new Students
            {
                StudId = s.StudentId,
                StudName = s.Name,
                StudAdd = s.Address,
                StudGender = s.Gender,
                StudStd = s.Standard
            }
                );
            }
        );
            return ListStud;
        }
 
        [Route("~/api/User")]
        public List<User> get()
        {
            List<User> users = new List<User>();
            var query = (from a in entities.tblUsers
                         select a).ToList();
            query.ForEach(u =>
            users.Add(new User { username = u.UserName, password = u.Password }
            )
            );
            return users;
        }
