Abstract: The XML support included in SQL and DB2 for i with Release 7.1 does not only allow XML
documents to be generated, but also allow XML documents to be consumed. Annotated XML
Document Decomposition is a SQL stored procedures that shreds XML documents based on
registered XML schemas directly into database tables. With the XMLTABLE table function
XML documents can be parsed, converted into a relational representation and data picked
specifically out. Additional scalar functions allow SQL to directly access XML documents
located within the IFS (Integrated File System) or in source physical file members. Last but
not least new SQL functions for getting access to web services are introduced. In
composition with the XMLTABLE function the XML answers returned by web services can be
consumed. The focus of this session is parsing XML documents located in either SQL tables
or within the IFS or returned by web services.
Learning Objectives:
Learn how well-formed XML documents located in either the IFS or an XML column can be
parsed with the XMLTABLE table function, converted into a relational representation and
data specifically selected. You’ll also get an overview over the new http-functions and how to
use them for getting access to web services.
Audience: Developers and Users who are experienced in SQL Queries and need to process XML
documents located in either SQL tables or the IFS or look for an easy way to access web
services or simply want to enhance their SQL know-how.
