Popular Subcategories: The DPL extension (version 2.3.0) produced a SQL statement which lead to a Database error.
The reason may be an internal error of DPL or an error which you made,
especially when using DPL options like titleregexp.
Query text is:
SELECT DISTINCT `page`.page_namespace AS page_namespace,`page`.page_title AS page_title,`page`.page_id AS page_id, rev_user, rev_user_text, rev_comment, rev_timestamp FROM `revision` AS rev, `page` WHERE 1=1 AND `page`.page_namespace IN (14) AND `page`.page_is_redirect=0 AND `page`.page_id=rev.rev_page AND rev.rev_timestamp=( SELECT MAX(rev_aux.rev_timestamp) FROM `revision` AS rev_aux WHERE rev_aux.rev_page=rev.rev_page ) ORDER BY rev_timestamp DESC LIMIT 5 OFFSET 0

Error message is:

We start with an example found in OOoForum under the title : Setting the page properties/margins directly from java

Here is the Java code : 

//Listing 33 A Java Code Example
// Java
// create new writer document and get text, then manipulate text 
 XComponent xWriterComponent = newDocComponent("swriter"); 
 XTextDocument xTextDocument = (XTextDocument)UnoRuntime.queryInterface(XTextDocument.class,xWriterComponent); 
 // Access the text document's multi service factory, which we will need for most of the 
 // following examples 
 mxDocFactory = (XMultiServiceFactory) UnoRuntime.queryInterface
		(XMultiServiceFactory.class,xTextDocument); 
 XText xText = xTextDocument.getText(); 
 // create a text cursor from the cells XText interface 
 XTextCursor xTextCursor = xText.createTextCursor(); 
 // Get the property set of the cell's TextCursor 
 XPropertySet xTextCursorProps = (XPropertySet)UnoRuntime.queryInterface
		(XPropertySet.class,xTextCursor); 
 // Page Style name 
 String pageStyleName= xTextCursorProps.getPropertyValue("PageStyleName").toString(); 
 // Get the StyleFamiliesSupplier interface of the document 
 XStyleFamiliesSupplier xSupplier = (XStyleFamiliesSupplier) UnoRuntime.queryInterface
		(XStyleFamiliesSupplier.class,xTextDocument); 
 // Use the StyleFamiliesSupplier interface to get the XNameAccess interface of the 
 // actual style families 
 XNameAccess xFamilies = (XNameAccess)UnoRuntime.queryInterface(XNameAccess.class,
		 xSupplier.getStyleFamilies()); 
 // Access the 'PageStyles' Family 
 XNameContainer xFamily = (XNameContainer) UnoRuntime.queryInterface
		(XNameContainer.class,xFamilies.getByName("PageStyles")); 
 // Insert the newly created style into the PageStyles family 
 XStyle xStyle= (XStyle) UnoRuntime.queryInterface(XStyle.class,xFamily.getByName
		(pageStyleName)); 
 // Get the property set of the TextCursor 
 XPropertySet xStyleProps = (XPropertySet)UnoRuntime.queryInterface
		(XPropertySet.class,xStyle); 
 xStyleProps.setPropertyValue("LeftMargin",new Short((short)1200)); 
 xStyleProps.setPropertyValue("RightMargin",new Short((short)1200)); 
 xStyleProps.setPropertyValue("BottomMargin",new Short((short)1200));

Have a look at com.sun.star.text.XTextDocument, com.sun.star.beans.XPropertySet, com.sun.star.style.XStyleFamiliesSupplier, com.sun.star.container.XNameContainer et com.sun.star.style.XStyle interfaces before the C++ translation which gives : 

//Listing 34 The corresponding C++ Translation
// C++
// create new writer document and get text, then manipulate text 

// Don't forget to add : using namespace com::sun::star::text;
// Don't forget to add : #include <com/sun/star/text/XTextDocument.hpp>
// Don't forget to add "com.sun.star.text.XTextDocument \" in the makefile

// Don't forget to add : using namespace com::sun::star::beans;
// Don't forget to add : #include <com/sun/star/beans/XPropertySet.hpp>
// Don't forget to add "com.sun.star.beans.XPropertySet \" in the makefile
// Don't forget to add : using namespace com::sun::star::style;
// Don't forget to add : #include <com/sun/star/style/XStyleFamiliesSupplier.hpp>
// Don't forget to add "com.sun.star.style.XStyleFamiliesSupplier \" in the makefile
// Don't forget to add : using namespace com::sun::star::container;

// Don't forget to add : #include <com/sun/star/container/XNameContainer.hpp>
// Don't forget to add "com.sun.star.container.XNameContainer \" in the makefile

// Don't forget to add : #include <com/sun/star/style/XStyle.hpp>
// Don't forget to add "com.sun.star.style.XStyle \" in the makefile

// the first line cannot be translated : already done in our main()
// XComponent xWriterComponent = newDocComponent("swriter"); 
 
	Reference < XTextDocument > xTextDocument (xWriterComponent,UNO_QUERY);
 // Access the text document's multi service factory, which we will need for most of the
 // following examples
	Reference< XMultiServiceFactory > mxDocFactory(xTextDocument,UNO_QUERY);
	Reference< XText > xText = xTextDocument->getText();
 // create a text cursor from the cells XText interface
	Reference< XTextCursor > xTextCursor = xText->createTextCursor(); 
 
 // Get the property set of the cell's TextCursor
	Reference< XPropertySet > xTextCursorProps(xTextCursor,UNO_QUERY); 
 
 // Page Style name 
 //*** I add a intermediate variable because of Any type returned by getPropertyValue 
	Any pageStyleName2 = xTextCursorProps->getPropertyValue
							(OUString::createFromAscii("PageStyleName"));
	OUString pageStyleName;
	pageStyleName2 >>= pageStyleName ;

  // Get the StyleFamiliesSupplier interface of the document
	Reference< XStyleFamiliesSupplier > xSupplier(xTextDocument,UNO_QUERY);

 // Use the StyleFamiliesSupplier interface to get the XNameAccess interface of the
 // actual style families
	Reference< XNameAccess > xFamilies(xSupplier->getStyleFamilies(),UNO_QUERY);

 // Access the 'PageStyles' Family 
	Reference< XNameContainer > xFamily(xFamilies->getByName
				(OUString::createFromAscii("PageStyles")),UNO_QUERY);
// Insert the newly created style into the PageStyles family
	Reference< XStyle > xStyle(xFamily->getByName(pageStyleName),UNO_QUERY);

 // Get the property set of the TextCursor 
	Reference< XPropertySet > xStyleProps(xStyle,UNO_QUERY);
	Any lm, rm, bm;
	lm<<=(short)1200; rm<<=(short)1200; bm<<=(short)1200;
	xStyleProps->setPropertyValue(OUString::createFromAscii("LeftMargin"),lm);
	xStyleProps->setPropertyValue(OUString::createFromAscii("RightMargin"),rm);
	xStyleProps->setPropertyValue(OUString::createFromAscii("BottomMargin"),bm);

My skills on Any type is not complete enough, then I don't find a straight forwarder way in using Any than using intermediate variables. See the last three lines for instance.
