Bulk Load vs Shredding

Do both methodologies achieve the same goal; migrating data from a given XML
element to its corresponding column in a relational table?
If that is correct, I would appreciate your comments asserting why one
methodology should be used rather than the other.

However, it it less flexible, since it needs an annotated schema, whereas
OpenXML's shredding is more flexible with XPath, but since it loads all the
data apriori, is not as fast and scalable...

I'm trying to kill several birds with as few stones as possible; using the
XmlTextWriter to write a file on the disk, get the data from that file and
map its data to table(s) in SQL Server and then based on a choice selected
in the form used to construct the XML apply a given XSLT to HTML or display
the raw XML in the browser.

Build-In Functions

Hi,
We are migrating from MS Access to Reporting Services.
When building a query in MS Access we have the possibility to create
functions with the expression builder.
The builder contains a lot of standard functions (Built-In Functions).
Question 1:
Is there such a system when building queries for Reporting Services.
Question 2:
It is possible to create user_defined functions in SQL-server.
Are there libraries outhere of user_defined functions Microsoft or the
community has build ?
Thanks for you reply.....
Regards,
Frank1. Yes there is a query builder built in to the development environment (
pretty much the same thing as in Access.)
2. Yes you can create UDFs in SQL... Many people share their UDFs on the
web, you just have to search or ask onthe newsgroups. Additionally RS allows
the use of Excel, and VB functions automatically...
