Create a table of XML documents with a type of XML. Use a primary key (you can't use an XML type) so add a field of type INT that is an identity.
Insert several records into the XML field in this new table. Use the following template:
Once these have been added, modify the structure of XML inside of your XML typed field to add another tag of <Material></Material>
Within the Features tag, use the "modify" function to make this happen.
Once this is complete, write an XQuery query using the value clause to return a single record.
CREATE TABLE script, the INSERT statements, the "modify" script, and the XQuery script.
Please find attached SQL script. It will first create a table product with identity ...
The solution contains SQL script that creates database table, inserts a couple of XML records, then runs XPath based queries to update or fetch records.
