Question

My SQL stored procedure is as follows:

CREATE  PROCEDURE [dbo].[GetTradeByLevel](
@LevelId INT                  
)
AS
BEGIN
if(@LevelId=1)
BEGIN
select * from CHANNELCLASS 
select a.* from accountmaster a join CHANNELCLASS b on        a.ChannelClassificationId=b.ChannelClassificationId 
select r.* from REGION r join accountmaster a on r.Accountid=a.AccountID 
select s.* from STORE s join REGION r on s.RegionID=r.RegionId
END
else if(@LevelId=2)
BEGIN
select a.* from accountmaster a join CHANNELCLASS b on  a.ChannelClassificationId=b.ChannelClassificationId
select r.* from REGION r join accountmaster a on r.Accountid=a.AccountID
select s.* from STORE s join REGION r on s.RegionID=r.RegionId
END
else if(@LevelId=3)
BEGIN
select r.* from REGION r join accountmaster a on r.Accountid=a.AccountID
select s.* from STORE s join REGION r on s.RegionID=r.RegionId
END
else if(@LevelId=4)
BEGIN
select s.* from STORE s join REGION r on s.RegionID=r.RegionId
END
END

I have to call this stored procedure in C# console application. If my parameter value is 1 it means I have to store 4 table values in a C# List<>. I have tried, but it stores only the first table’s data.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.Data.SqlClient;

namespace ConsoleApplication3
{
class Program
{
    static void Main(string[] args)
    {
        int v = 1;
        int cl;
        SqlConnection con = new SqlConnection("Data Source=CTSINDLFVMOSS;Initial Catalog=DB_CGTPO_DEVE;User ID=DB_CGTPO_DEVE;Password=cgtpo");
        con.Open();
        SqlCommand cmd = new SqlCommand("GetTradeByLevel", con);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@LevelId", v);
        List<string> customers = new List<string>();
        using (SqlDataReader dr = cmd.ExecuteReader())
        {
            cl = dr.FieldCount;
            while (dr.Read())
            {
                for (int i = 0; i < cl; i++)
                {
                    customers.Add(dr[i].ToString());
                    //customers.Add(dr[1].ToString());
                    //customers.Add(dr[2].ToString());
                }
            }
        }
        for (int i = 0; i < customers.Count; i++) // Loop through List with for
        {
            Console.WriteLine(customers[i]);
        }
        con.Close();
    }
    }
}

yupes NextResult()

example:

dim dr as sqldatareader = <your command that will return data>

while dr.read
'do stuff
end while

dr.NextResult()

while dr.read...

if you perform multiple selects in your stored procedure, all will be contained in the SqlDataReader, it’s just your method of advancing the reader…
