comment_icon 0 Learning Resources for DB2 pure XML with samples


XForms and DB2 pureXML
Handle pureXML data in Java applications with pureQuery



pureXML Samples

The pureXML feature enables well-formed XML documents to be stored in their hierarchical format within columns of a table. XML columns are defined with the new XML data type. Because the pureXML feature is fully integrated into the DB2 database system, the stored XML data can be accessed and managed by leveraging DB2 functionality. This functionality includes administration support, application development support and efficient search and retrieval of XML via support for XQuery, SQL or a combination of SQL/XML functions.
There are various samples provided to demonstrate the XML support; these are broadly categorized as:
Administration samples
These samples demonstrate the following features:
  • XML schema support : Schema registration and validation of XML documents
  • XML data indexing support : Indexes on different node types of XML value
  • Utility support for XML : Import , export, runstats, db2look, and db2batch support for the XML data type
Application Development samples
These samples demonstrate the following features:
  • XML insert, update, and delete : Inserting XML values in XML typed columns, updating and deleting existing values
  • XML parsing, validation, and serialization support : Implicit and explicit parsing of compatible data types, validating an XML document, serializing XML data
  • Hybrid use of SQL and XQuery : Using SQL/XML functions like XMLTABLE, XMLQUERY and the XMLEXISTS predicate
  • XML data type support in SQL and external procedures: Passing XML data to SQL and external procedures by including parameters of data type XML
  • Annotated XML schema decomposition support : Decomposing an XML document based on annotated XML schemas
  • XML publishing functions : Using functions to construct XML values
XQuery samples
These samples demonstrate the use of axes, FLWOR expressions, and queries written with XQuery and SQL/XML.
These samples can be found in the following location:
  • On Windows: %DB2PATH%\sqllib\samples\xml (where %DB2PATH% is a variable that determines where DB2® database server is installed)
  • On UNIX: $HOME/sqllib/samples/xml (where $HOME is the home directory of the instance owner)
