How do I get a document handle in Open XML?
First, sp_xml_preparedocument is called to obtain a document handle. This document handle is passed to OPENXML. In the OPENXML statement, the rowpattern ( /ROOT/Customers) identifies the nodes to process.
How is element-centric mapping applied to XML documents?
Therefore, element-centric mapping is applied. The XML document in this example is made up of the < Customer > and < Order > elements. The OPENXML statement retrieves a rowset that is made up of the oid attribute from the < Order > element, the ID of the parent of the node identified by rowpattern, and the leaf-value string of the element content.
