I am having some trouble getting the correct syntax for a bit if code. I am using vb to insert data into a db and outputting the data as XML, here is the code
<WebMethod()> _
Public Function addTrack(ByVal tTitle As String, ByVal tAlbum As String, ByVal tGenre As String) As String
Dim conn As New SqlConnection("Data Source=MARTIN-LAPTOPSQLEXPRESS;Initial Catalog=mp3_playlists;Integrated Security=True")
Dim sql As String = "INSERT INTO Tracks (trackTitle, trackAlbum, trackGenre) VALUES ('" & tTitle & "', '" & tAlbum & "', '" & tGenre & "') FOR XML AUTO, ELEMENTS"

The code is for a ASP.NET web service, when I click invoke on the website i get the error Incorrect syntax near the keyword 'FOR'. If I remove FOR XML AUTO, ELEMENTS everything works find, db updates but I dont get the data to output as XML. I think the issue is with the brackets required for the insert values because this issue does not occur if the SQL statement is a SELECT statement which has no brackets but i just cant figure out the correct syntax?

I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)

How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)
