How to export a DataTable to Xml with ALL columns as attributes?

Question

Question: I\'m exporting a System.Data.DataTable to XML. So far it works fine. But I want to have all the data in attributes, which works fine as well. But my problem now, i

Answer 1

Two points:

First: The ExportTable() threw an exception: "DataTable already belongs to another DataSet." When I executed:

ds.Tables.Add(dtt)

I corrected this by making a local copy of the table:

Dim dtX As DataTable = dtt.Copy
ds.Tables.Add(dtX)
ds.DataSetName = strTable

This worked well.

Second: If you use the XML to create a dynamic SQL statement, there is no need to be concerned about the columns/fields with NULL value being omitted in the XML export. Simply walk through the a attributes that are in the XML record, build the INSERT or UPDATE statement and execute a connection command. This is faster than using a DataSet.

For INSERT it has one drawback. If the primary key is created by incrementing an identity column, an ADO.Net DataSet will return it. Dynamic SQL will require a SELECT statement to retrieve it.

Also, it would be good idea to obfuscate your code.
