Convert XML in SQL Server

This is seriously cool.

In my C# I have read an xml file into a byte[] and stored it within the database in a varbinary(max) column.

If I wish to see this file as Xml in the database, all i need to do is the following SQL.

SELECT CONVERT(Xml, Source)
FROM MyFiles
WHERE MyFileID=7

Now what is even cooler, is if wish to validate said file against an Xml Schema, i can do the following.

SELECT CONVERT(Xml(MySchema), Source)
FROM MyFiles
WHERE MyFileID=7

So this is a really nice way of validating data in the database against an xml schema where you might not necessarily be able to used an Xml Typed column (accepting multiple file types)
