Automagically create database schema from XML dataset
I am trying to create a database from an XML file. I am able to create a dataset from the XML doc, but how can I create a database schema from the dataset and populate the database? Or is this even possible using VS.NET 2003?
Part of the XML file follows. Thanks for any help.

Has anyone run into problems creating typed datasets from complex schemas?
I am attempting to create a Typed Dataset in Visual Studio .Net from a .xsd

it is just something odd about .Net's parser. Here is the section of the

I have converted some reports in Access to SQL 2008 Reporting Services.
However, some of the reports have subreports in them and they look fine in
design but when I try to run the report previewing it from VS 2008 I get the
main report but not the subreport. Apparently, the subreport is not tied to
a Dataset even though the dataset shows up in the Report Data section on left

I transfer data from a dataset to an XML-document by

can I force to generate elements (with no content) for
this kind of datafields ?

I want to take a dataset and save the data as an xml document. I know how
to do this, but I need the xml to be formatted in a certain way. What are
my options? I have thought about using a stylesheet to format from xml to
xml. I can create an xsd, but that does not seem to save the dataset the
way I need it. It just adds the schema to the top, but does not put the xml
in a hierarchical format.
You can do it using the XMLdoc.
Because I do not know what you are reformating it is difficult to say more.

Before a delete on any table, I would like to write the contents of the
soon-to-be-deleted row to that application's single "graveyard" table
(alternate: or document as coded below).
SQL Server 2005 solution: I would store the tablename, today's date,
username, and the key column values of the soon-to-be deleted row as the
composite key of the new graveyard table row. The soon-to-be-deleted row's
data would be stored in a single xml-type column.
XML File solution: composite key from above would be the name of a
filename.xml file. The data from the soon-to-be-deleted...Lookup in DataGridView? Any Progress? Worth Trying?

Any suggestions, comments welcome.
probably you will encounter problems when opening this with Excel:

your dataset on several worksheets
- Depends on the dataset format (text format, Access database, etc.) ->
so you may provide some more details

I can easily create an xsd from an xml file in Visual Studio 2005. But
I want a typed DataSet, so is there an option to create that typed

so I don't want to create them from scratch.
On a sidenote: I am loading the XML from http, I transform it via xslt

lot of inefficient things. I am always having trouble with "how to get
