Extract the data from a table and create Output table value as XML using SSIS

In the present example I am using AdventureWorks2012 database. You could use any other database. I am writing a sql script that selects a number of columns from a table in the database using the For XML clause. The Select query would return an XML fragment from the database.
SELECT [BusinessEntityID]
      ,[PersonType]
      ,[NameStyle]
      ,[Title]
      ,[FirstName]
      ,[MiddleName]
      ,[LastName]
      ,[Suffix]
      ,[EmailPromotion]
      ,[AdditionalContactInfo]
      ,[Demographics]
  FROM [Person].[Person]
  FOR XML AUTO,ELEMENTS,ROOT('row')

See the output


We need to create an xml file which stores this xml result.
Open SSDT
Take Execute sql task

Double click on this and set the configuration.
Select Result set as XML
  
And create connection.

Select the source type as direct input and click on the SQL statement.

Click ok.

Create a variable
  
Now go to the Result set and map the variable name.

Click ok.
Now we need to take the Sql script task.
  
Double click on the Script task
Select the variable and click edit script button.


Writing the blow script
public void Main()
                                {
            //User::ResultSetXML
                                                // TODO: Add your code here
            string fileName = @"F:\TestXMLFile.xml";
            try
            {
                // Check if file already exists. If yes, delete it.
                if (File.Exists(fileName))
                {
                    File.Delete(fileName);
                }
                // Create a new file
                using (FileStream fs = File.Create(Dts.Variables["User::ResultSetXML"].Value.ToString()))
                {
                    // Add some text to file
                    Byte[] title = new UTF8Encoding(true).GetBytes("New XML File");
                    fs.Write(title, 0, title.Length);
                    byte[] author = new UTF8Encoding(true).GetBytes("Bagesh Kumar Singh");
                    fs.Write(author, 0, author.Length);
                }
            }
            catch (Exception Ex)
            {
                Console.WriteLine(Ex.ToString());
            } 
                                                Dts.TaskResult = (int)ScriptResults.Success;
                                }
