Call is not passing from controller to model in web api - oracle

Question

I am totally new in web api. I have created web api simply to retrive data from oracle DB with the help of few articles which i found on internet. I am trying to find out error since morning but no success till now. When i try to run the code, it dont give any error or anything. Debugger passed to my DB class and stops. Below is my controller code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Data;
using System.Data.SqlClient;
namespace iLearnWebApi.Controllers
{
public class ValuesController : ApiController
{
DAL.DBAccess dblayer = new DAL.DBAccess();
public DataSet Getrecord(int programid)
{
DataSet ds = dblayer.GetRecordbyid(programid);
return ds;
}
} }
And below is my DBClass code.

Can anyone please tell me what mistake i have done in above code.

This sounds like a routing issue (without seeing your route config).
Try changing: public DataSet Getrecord(int programid)
To: public DataSet Get(int id)
And call: localhost:60908/api/Values/1
