3 Why Overland Park Home (Lenexa, KS) of more than half of the IBM Informix Development and Support team - just a few miles down the road Central USA that is why the Airport is code name: MCI for Mid Continent International International Informix Users Group We Speak Informix!

4 Call for Presentations The Conference Planning Committee is currently accepting presentation proposals for the 2008 IIUG Informix Conference on Informix-related topics in any of the areas listed below. Subjects related to all current Informix and Informix-heritage products are welcome, as well as products that operate in those environments such as other IBM products, plus third party, Open Source and cross-platform products. Technical Session Tracks Conference sessions will be organized into four general subject area tracks that will run concurrently: The Database Applications and Tools track will cover such topics as application development tools and methodologies, application and database architecture, and maximizing application and SQL performance. The Informix Administration and Performance track will feature sessions on topics including database and data warehouse design and administration, performance tuning, backup and restore, and security. The Informix Edge track will contain talks on aspects of Informix that provide a distinct edge in application development and processing such as emerging technologies like XML and Web services, operation in crossplatform and heterogeneous environments, and support for Open Source and third-party tools. The Advanced Support Topics track will feature studies and advanced sessions on support topics, many taken from real-life development and support scenarios. Session Topics A survey was recently conducted to help determine the technical topics that would be of most interest to attendees. One key finding was that there is significant interest across a broad range of Informix-related subject areas. If you are knowledgeable in an Informix-related area, there are likely a number of other users that would like to hear about it. Some areas that scored particularly high on the survey were: Performance Tuning and Monitoring SQL Optimization Replication Development Languages, Tools and Web Programming Linux and Open Source Web Services and SOA Encryption, Auditing and Compliance Advanced Support Case Studies and Topics New Features in IDS 11 / Cheetah Interested in Presenting.

17 What s in Cheetah? IDS Client genxml functions genxml() genxmlelem() genxmlqueryhdr() UDR invoking the XSLT4C and XML4C libraries within IDS XSLT4C Processor XML4C Parser IDS Client Extract functions extract() extracevalue() existsnode() idsxmlparse() Informix Dynamic Server ICU XSLT4C and XML4C

18 What s in Cheetah? XML Publishing Functions Genxml() and GenxmlClob() Genxmlqueryhdr() and GenxmlqueryhdrClob() Genxmlelem() and genxmlelemclob() XPath functions for pattern matching and extraction within XML document Extract() and Extractclob() ExtractValue() ExistsNode() idsxmlparse()

19 Genxml() and GenxmlClob() Genxml(row_for_publishing, doc name ) returns lvarchar(32739) Built-in function Aggregate function Output limited to max size of lvarchar bytes Resultset larger than that will raise error SELECT genxml(row(c.cno, c.fname, c.lname, o.ordid), cust_order') FROM customer c, orders o Where c.cno = and o.ord_date = 05/20/2006 c.cno = o.cno; GenxmlClob() -- Same except the return type is CLOB for larger docs

20 Genxml() and GenxmlClob() SELECT genxml(classes, row ) from classes where classid < 5;; SELECT genxmlclob(classes, row ) from classes where classid < 5; The output for both queries (type is different) : (expression) <row classid="1" class="125" subject="chemistry"/><row classid="2" class="250" subject="physics"/><row classid="3" class="375" subject="mathematics"/><row classid="4" class="500" subject="biology"/>

21 Genxmlelem() and GenxmlelemCLOB() Same as Genxml() except generates tags for each element separately SELECT genxmlelem(row(c.cno, c.fname, c.lname, o.ordid), cust_order') FROM customer c, orders o Where c.cno = and o.ord_date = 05/20/2006 c.cno = o.cno;

22 Genxmlquery() and GenxmlqueryClob() Genxmlquery( docname, query) returns lvarchar(32760) GenxmlqueryClob( docname, query) returns Clob Makes it easier to generate queries for static queries No need to write the ROW( ) in the projection list. Only XML document is returned Query passed in will have to be prepared and executed everytime. The elements name will be same as the column names in projection list.

23 Genxmlqueryhdr() and GenxmlqueryhdrClob() EXECUTE FUNCTION genxmlqueryhdr('manufact_set','select * FROM manufact'); (expression) <?xml version="1.0" encoding="iso "?> <!DOCTYPE manufact_set SYSTEM "../manufact_set.dtd"> <?xml-stylesheet type="text/xsl" href="../manufact_set.xsl"?> <manufact_set> <row> <manu_code>smt</manu_code> (removed for brevity) <manu_code>nkl</manu_code> <manu_name>nikolus </manu_name> <lead_time> 8</lead_time> </row> <row> <manu_code>prc</manu_code> <manu_name>procycle </manu_name> <lead_time> 9</lead_time> </row> </manufact_set> 1 row(s) retrieved.

24 Extract() and ExtractValue() SELECT extract(col2, '/personnel/person[3]/name/given') FROM tab; SELECT extractvalue(col2, '/personnel/person[3]/name/given') FROM tab; execute function extract( <person><name><fname>john</fname><lna me>kelly</lname></person>, /person/name/lname ); select col1 from tab where existsnode(col2, '/personnel/person/*/ ') = 1;

25 ExtractClob() and ExtractValueClob() SELECT extractclob(col2, '/personnel/person[3]/name/given') FROM tab_clob_neg; SELECT extractvalueclob(col2, '/personnel/person[3]/name/given') FROM tab_clob_neg;

26 ExistsNode() SELECT customer, extract(purchaseorder, ) AS purchase_orders FROM orders WHERE existsnode(purchaseorder, /purchaseorder[list/item/desc/text = Shoes ] ) = 1;

27 IDS XML Roadmap

28 XML Extraction (In IDS Cheetah) Support extraction of xml nodes from an XML document via XPATH expression SELECT customer, extract(purchaseorder, ) AS purchase_orders FROM orders WHERE XMLExists(purchaseOrder, /purchaseorder[list/item/desc/text= Shoes ] ); Support extraction of values from an XML document via XPATH expression SELECT customer, extract(purchaseorder, /purchaseorder/@orderdate ) AS purchase_orders FROM orders WHERE XMLExists(purchaseOrder, /purchaseorder[list/item/desc/text= Shoes ] );

29 Fulltext Index for XML Use when you store XML documents into columns Helpful when looking for an XPath expression in the doc. Efficient because the XPath expression is evaluated by the index SELECT customer, address XML Document AS purchase_orders FROM orders WHERE XMLExists(purchaseOrder, /purchaseorder[list/it em/desc/text= Shoes ] ); XMLExists evaluates the document for XPath expression and XML aware index should handle it. XPath Expression

30 XML Shredding Shredding is the mechanism to map XML schema into relational schema and shred the XML document into relational tables. Schema has annotations indicating how xml data is entered into database Based on actual values and serializations of input Applications register Schema with IDS. Then, simply use stored procedures to shred XML documents and insert into tables. xdbdecompxml(rschema,xmlschemaname,xmldoc,documentid, Validation_flag, )

31 XSLT Transformation XSLT is used to transform XML documents XML to XML (transform to confirm different schema/standard) XML to HTML XML to PDF The XSLT DataBlade creates several UDRs that take an XML document and an XSL stylesheet as input and return the transformed document -- Transforming XML documents stored in tables select xslt_transform(s.style_doc, x.xml_doc) FROM style_sheets s, xml_docs x WHERE s.style_title = 'ecommerce_root.xsl' AND x.xml_transaction_id = 12345; -- Transforming dynamically generated XML documents select xslt_transform(s.style_doc, genxml( transaction, row(o.trnid, o.custid, o.addr))) FROM style_sheets s, orders o WHERE s.style_title = 'ecommerce_root.xsl' AND o.trnid = 12345;
