C#

// if you fetch all data from sql table into DataTabl dt; then use this logic 
//otherwise use Solution 1 

            DataTable dt = new DataTable();
            string item_id = string.Empty;
            DataRow[] datarows =  dt.Select("item_id = '" + item_id + "'");

            string result = item_id;

            foreach (DataRow dr in datarows)
            {
                result += "," + dr["Item"].ToString();
            }

            //you can use result;
            //TODO:
            Console.WriteLine(result);
