Question

 SELECT distinct r.rate as Rate,f.bthid as Batchid,CASE  WHEN r.rate = '1' THEN '100' WHEN r.rate = '2' THEN '75' WHEN r.rate = '3' THEN '50' WHEN r.rate = '4' THEN '25' ELSE '0' END AS Translated_Rate FROM bthfac AS f,batch AS b, faculty AS fa,facfeedback AS r where  month(b.examdate)= '9' and year(b.examdate)= '2011' and b.bthid=f.bthid and r.bfid = f.bfid and fa.facname = 'MADHAVAN'

when i  execute the above query  output as follows;

rate  Batchid Translated_Rate

 0  13         0

3  13       50

4  9       25

1  8     100

4  14     25

Hi Can you try this too,

public static string Serialize(object dataToSerialize)     {         if(dataToSerialize==null) return null;          using (StringWriter stringwriter = new System.IO.StringWriter())         {             var serializer = new XmlSerializer(dataToSerialize.GetType());             serializer.Serialize(stringwriter, dataToSerialize);             return stringwriter.ToString();         }     }      public static T Deserialize<T>(string xmlText)     {         if(String.IsNullOrWhiteSpace(xmlText)) return default(T);          using (StringReader stringReader = new System.IO.StringReader(xmlText))         {             var serializer = new XmlSerializer(typeof(T));             return (T)serializer.Deserialize(stringReader);         }     }

Hi Good day,

Suppose I have a collection 

List<Employee> empList = new List<Employee>();

            empList.Add(new Employee() { ID = 1, FName = "John", LName = "Shields", DOB = DateTime.Parse("12/11/1971"), Sex = 'M' });

            empList.Add(new Employee() { ID = 2, FName = "Mary", LName = "Jacobs", DOB = DateTime.Parse("01/17/1961"), Sex = 'F' });

            empList.Add(new Employee() { ID = 3, FName = "Amber", LName = "Agar", DOB = DateTime.Parse("12/23/1971"), Sex = 'M' });

            empList.Add(new Employee() { ID = 4, FName = "Kathy", LName = "Berry", DOB = DateTime.Parse("11/15/1976"), Sex = 'F' });

            empList.Add(new Employee() { ID = 5, FName = "Lena", LName = "Bilton", DOB = DateTime.Parse("05/11/1978"), Sex = 'F' });

            empList.Add(new Employee() { ID = 6, FName = "Susanne", LName = "Buck", DOB = DateTime.Parse("03/7/1965"), Sex = 'F' });

            empList.Add(new Employee() { ID = 7, FName = "Jim", LName = "Brown", DOB =DateTime.Parse("09/11/1972"), Sex = 'M' });

            empList.Add(new Employee() { ID = 8, FName = "Jane", LName = "Hooks", DOB = DateTime.Parse("12/11/1972"), Sex = 'F' });

            empList.Add(new Employee() { ID = 9, FName = "Robert", LName = "", DOB =DateTime.Parse("06/28/1964"), Sex = 'M' });

            empList.Add(new Employee() { ID = 10, FName = "Cindy", LName = "Fox", DOB = DateTime.Parse("01/11/1978"), Sex = 'M' });


Code to convert to xml

var xEle = new XElement("Employees",

                from emp in empList

                select new XElement("Employee",

                             new XAttribute("ID", emp.ID),

                               new XElement("FName", emp.FName),

                               new XElement("LName", emp.LName),

                               new XElement("DOB", emp.DOB),

                               new XElement("Sex", emp.Sex)

                           ));
