Convert XML data into Relational Table data using Teiid

In this article I will show how to convert XML data into relational form using Teiid using "XMLTABLE" SQL/XML function. XMLTABLE is defined in SQL/XML 2006 specification and is supported by most major databases like Oracle, DB2 etc. XMLTABLE functionality is introduced in Teiid 7.0. If you are already familiar with using this function it is no different in using it in Teiid. Please see this WIKI article for complete information. Generating XML data from the Relational Data: If you need to produce the XML data Teiid provides various SQL/XML functions for that purpose too. Check out this article on the available SQL/XML functions . These are functions are also supported by Teiid. In a future article, we will how show you how to use these SQL/XML functions and create a web service by just using the Teiid Designer and Teiid.

Teiid 7.1 Final Released

Teiid 7.1 continues the 7.x series with numerous features and performance improvements. Here are some highlights: ODBC Support - Support for ODBC access is now available through PostgreSQL ODBC driver clients. See the Client Developer's Guide for more on how to use Teiid's ODBC access. Native Materialized Tables - views marked as materialized without a target table will be materialized internally by Teiid. Materialized view tables will be indexed by the primary key of the view if present and can be controlled through the expanded cache hint. There are also new system procedures refreshMatView and refreshMatViewRow to refresh materialized view table contents. Expanded Cache Hint - The cache hint can now specify pref_mem to indicate that data should prefer to be held in memory, ttl to indicate the time-to-live, and updatable to indicate that a materialized view with a primary key can be updated by row with the refreshMatViewRow system procedure. SQL Support Added NU

7.1 CR2

7.1 CR2 is now available. This should be the last CR prior to the final release. This CR provides an expanded cache hint to control result set cache and materialized view entries. VDB versioning, which allows multiple VDBs with the same name to be deployed at the same time, is now supported through the use of a file naming convention vdbname.version.vdb - dynamic VDBs may use use the vdb.xml version attribute to denote version. See the release notes in the kit and the JIRAs for more information. More documentation changes will be coming before the release. The Teiid Team
