Detailed Description

Parses an input XML tabular data stream, bind its data to a SQL statement and outputs resulting data as a tabular XML data stream.

Definition at line 76 of file sqlstreamer.hpp.

Public Methods
	SAXSQLHandler (DBStreamerFactory *p_pStreamerFactory, StreamerParams *p_pParameters, XMLFlowContext *p_pStreamContext, XMLStreamConsumer *p_pStreamConsumer)
	~SAXSQLHandler ()
	Destructor.
void	startDocument ()
	Receive notification of the beginning of a document. Inits parsing global variables.
void	startElement (const XMLCh *const uri, const XMLCh *const localname, const XMLCh *const qname, const Attributes &attrs)
	Receive notification of the beginning of an element. Updates paring depth.
void	characters (const XMLCh *const chars, const unsigned int length)
	Receive notification of character data. If parsing a "cell" of the tabular data, appends received characters to the field data buffer.
void	endElement (const XMLCh *const uri, const XMLCh *const localname, const XMLCh *const qname)
	Receive notification of the end of an element. If element is a "cell" of tabular XML data, tries to bind its content to the SQL statement. If element is a "row" of tabular XML data, performs flush and commit operations.
void	endDocument ()
	Receive notification of the end of a document. Performs last flush and commit operations.
void	ignorableWhitespace (const XMLCh *const chars, const unsigned int length)
void	processingInstruction (const XMLCh *const target, const XMLCh *const data)
void	setDocumentLocator (const Locator *const locator)
void	startPrefixMapping (const XMLCh *const prefix, const XMLCh *const uri)
void	endPrefixMapping (const XMLCh *const prefix)

Member Function Documentation

void SAXSQLHandler::characters (  const XMLCh *const    chars, const unsigned int    length )

Receive notification of character data. If parsing a "cell" of the tabular data, appends received characters to the field data buffer. Parameters: chars  The characters from the XML document. length  The number of characters to read from the array. Exceptions: SAXException  Any SAX exception, possibly wrapping another exception. Definition at line 167 of file sqlstreamer.cpp. References concatCharBuffer(), DEBUG_FUNC, XMLFlowContext::getTranscoder(), releaseCharBuffer(), and XSTR().

void SAXSQLHandler::endDocument (    )

Receive notification of the end of a document. Performs last flush and commit operations. Exceptions: SAXException  Any SAX exception, possibly wrapping another exception. XMLFlowException  ERRCODE_CAUSE_DATAACCESS Definition at line 258 of file sqlstreamer.cpp. References CATCH_XML_FLOW_ERROR_RELEASE_AND_RETURN, DEBUG_FUNC, ON_XML_FLOW_ERROR_DO, PREP_CATCH_XML_FLOW_ERROR, SQLSTREAMER_TAGNAME, and WATCH_XML_FLOW_ERROR.

void SAXSQLHandler::endElement (  const XMLCh *const    uri, const XMLCh *const    localname, const XMLCh *const    qname )

Receive notification of the end of an element. If element is a "cell" of tabular XML data, tries to bind its content to the SQL statement. If element is a "row" of tabular XML data, performs flush and commit operations. Parameters: uri  The URI of the asscioated namespace for this element localname  The local part of the element name qname  The QName of this element Exceptions: SAXException  Any SAX exception, possibly wrapping another exception.
