Office Documents - Using XQuery with ODF & OOXML

New office document standards like the OpenDocument Format(ODF) and Office Open XML (OOXML) are making office document integration in business processes a reality. This article discusses using XQuery to query these formats of office documents.

Quick Start

This quick start provides basic information for getting started with DataDirect XQuery® immediately after installation. In addition, this quick start describes the DataDirect XQuery® command-line utility that is available for quickly running and testing XQueries through a console window.

XQueryWebService Example

Follow along with this example on XQueryWebService that shows how to create a web service using DataDirect XQuery®. View as either as an HTML or as a downloadable PDF. This example has been tested using Tomcat 5.x and 6.x.

Updating Relational Data with DataDirect XQuery®

DataDirect XQuery® supports updates to relational database tables from inside an XQuery by providing three built-in functions. These functions are: ddtek:sql-insert, ddtek:sql-update, ddtek:sql-delete. The DataDirect XQuery® update functionality requires extensions to the XQuery processing model for function declaration, XQuery expressions, and snapshot semantics.

Resolving fn:collection() Errors

No standard way exists to access a relational table in XQuery, so each XQuery implementation defines its own way to do this. DataDirect XQuery® uses fn:collection() to access a relational table. This paper provides guidelines to help you troubleshoot and correct common causes of errors that occur when using fn:collection() in an XQuery query.

Update on XQJ: XQuery API for Java

XQJ enables a Java application to submit XQuery queries to an XML data source and process the results. XQJ is analogous to JDBC, which in conventional SQL environments, a Java application uses to connect to a database, issue SQL queries, and obtain result sets. So, XQJ is to XQuery what JDBC is to SQL.

XML Examples

DataDirect XQuery wants you to learn more about how you can get software to work for you. So, we've put together numerous pages that provide a comprehensive set of XML tools and features for working with XML, XQuery, SQL/XML, Web services, XML publishing, and many other XML technologies.

JDBC Pooling

Connection pooling allows your application to reuse connections. DataDirect XQuery® supports connection pooling through JDBC. Learn how to configure JDBC connection pool managers in several popular application server environments including Tomcat, JBoss, BEA WebLogic, and IBM WebSphere Application Server.

MySQL Examples

Users with MySQL database deployments (Enterprise version) can now take advantage of all the benefits of DataDirect's XQuery engine. The following examples show you how you can use DataDirect XQuery to work with data in a MySQL relational database.
