i need help with a reader that is within a dataset

Question

public OdbcDataReader SelectDataReader(string connString,string Columns,string TableName,string Filters, string OrderBy)
{

OdbcDataReader MyReader;
System.Data.Odbc.OdbcConnection odbcConn = new System.Data.Odbc.OdbcConnection(connString);
string strSQL;
strSQL="SELECT " + Columns + " ";
strSQL+="FROM " + TableName + " ";

if (Filters.Length!=0)
{
strSQL+="WHERE " + Filters + " ";
}


if (OrderBy.Length!=0)
{
if (OrderBy.StartsWith("LIMIT 0,"))
strSQL+=OrderBy + " ";
else
strSQL+="ORDER BY " + OrderBy + " ";
}
System.Data.Odbc.OdbcCommand odbcCommand = new System.Data.Odbc.OdbcCommand(strSQL);
odbcCommand.Connection=odbcConn;
odbcCommand.Connection.Open();
try
{
MyReader=odbcCommand.ExecuteReader();
return MyReader;
}
catch(Exception exc)

{
throw exc;
}






}

this is where i am calling the method

private DataSet CreatePostDataTable(int type)
{

string sRequestID = Request.QueryString["rID"].ToString();
DataSet myDs = new DataSet();
string sSQL = "";
sSQL = " CONCAT('<a class=hyperlinksBlue href=''#'' onclick=window.open(''../default.aspx?tID=',topicID,'&rID=', RequestID,'''',',''myWindow''',',''width=600,height=600,location=no,menubar=no,scrollbars=yes,resizable=yes''',')>',Subject , '</a> <i>',username,'</i> <font color=''#a9a9a9''>',' on ',DATE_FORMAT(createdate, '%m/%d/%Y'),'</font>') as topics ";
myDs = daData.SelectDataODBC(Session["connITRequest"].ToString(),sSQL,"tbltopic","(type='"+type+"') and (requestID="+sRequestID+")","topicID desc");


for (int i =0; i < myDs.Tables[0].Rows.Count; i++)
{

//get the topic ID first.
string sTopicID = myDs.Tables[0].Rows[i][0].ToString();
int Beg=sTopicID.IndexOf("?tID=") + 5 ;
sTopicID=sTopicID.Substring(Beg);
int End=sTopicID.IndexOf("rID=") - 1;
sTopicID=sTopicID.Substring(0,End);
//Find the total number of posts. (Topic (posts) on main page)
MyNewReader= SelectDataReader(Session["connITRequest"].ToString(),"Count(*) as Replies","tblpost","topicID="+sTopicID,"topicID desc");


}
return myDs;

}

i am calling the method above and i need help. as you see i am picking up the id from the dataset and passing it to the method and looping through and calling it according to the dataset. is there a way to move the reader to the next position to add the value again to it. it is only picking up the last values but i need it to add every value to the reader. should i use an array to call or any ideas would help. thanks


here is where i am calling it everytime but i need to store all values but it is storing the last one of course, once the first one is stored i need to move the position to next, any ideas? thanks in advance

MyNewReader= SelectDataReader(Session["connITRequest"].ToString(),"Count(*) as Replies","tblpost","topicID="+sTopicID,"topicID desc");
