Challenge:
Question 34
The sp_XML_PrepareDocument stored procedure requires a parameter that is an XML data type. What is the output

parameter for?

1.The handle as an INT
2.The handle as an XML
3.The handle as a Varchar

Correct Answer:
The correct choice is #1: The handle as an INT

Explanation:
sp_XML_PrepareDocument requires two parameters. The first parameter is an INTEGER that is declared as OUTPUT. This parameter will be the handle to use in further queries to retrieve the XML data you want. The second
parameter for sp_XML_PrepareDocument is the variable defined as type XML, with contains the XML data you want to store in SQL Server’s memory.

Explanation
Reads the Extensible Markup Language (XML) text provided as input, then parses the text using the MSXML parser (Msxml2.dll), and provides the parsed document in a state ready for consumption. This parsed document is a tree representation of the various nodes (elements, attributes, text, comments, and so on) in the XML document.

sp_xml_preparedocument returns a handle that can be used to access the newly created internal representation of the XML document. This handle is valid for the duration of the connection to Microsoft® SQL Server™ 2000, until the connection is reset, or until the handle is invalidated by executing sp_xml_removedocument.

Note A parsed document is stored in the internal cache of SQL Server 2000. The MSXML parser uses one-eighth the total memory available for SQL Server. To avoid running out of memory, run sp_xml_removedocument to free up the memory.

Syntax

sp_xml_preparedocument hdoc OUTPUT
[, xmltext]
[, xpath_namespaces]

Arguments

hdoc

Is the handle to the newly created document. hdoc is an integer.

[xmltext]

Is the original XML document. The MSXML parser parses this XML document. xmltext is a text (char, nchar, varchar, nvarchar, text, or ntext) parameter. The default value is NULL, in which case an internal representation of an empty XML document is created.

[xpath_namespaces]

Specifies the namespace declarations that are used in row and column XPath expressions in OPENXML. The default value is .
xpath_namespaces provides the namespace URIs for the prefixes used in the XPath expressions in OPENXML by means of a well-formed XML document. xpath_namespaces declares the prefix that must be used to refer to the namespace urn:schemas-microsoft-com:xml-metaprop, which provides meta data about the parsed XML elements. Although you can redefine the namespace prefix for the metaproperty namespace using this technique, this namespace is not lost. The prefix mp is still valid for urn:schemas-microsoft-com:xml-metaprop even if xpath_namespaces contains no such declaration. xpath_namespaces is a text (char, nchar, varchar, nvarchar, text, or ntext) parameter.

The handle serves as our “claim ticket” for getting the data back.

Pretty cool, thanks!

Option 1 is correct.

Since we need to get the handle number(i.e claim ticket) of the xml saved in the memory, and our handle will be an integer and even to open the ticket we need the int handle

33) The sp_XML_PrepareDocument stored procedure requires a parameter that is an XML data type. What is the output parameter for?

1) The handle as an INT

First parameter integer holds the handle value of XML data passed in second parameter. using this integer value in openXml function to get rowset of records.

Option 1 is the correct Answer “The handle as an INT”

As According To MSDN :
/*
sp_xml_preparedocument
hdoc
OUTPUT
[ , xmltext ]
[ , xpath_namespaces ]

hdoc
Is the handle to the newly created document. hdoc is an integer.
*/

Declare @hdoc integer
Declare @Doc xml
–Set @Doc with required xml
EXEC sp_xml_preparedocument @hdoc OUTPUT, @Doc

when you send an XML document to be tailored into memory, SQL Server gives you a claim number (called a handle) in the form of an integer which you need later when referring to that document.

Explanation :

sp_XML_PrepareDocument which is a system supplied stored procedure reads the xml which is given as a input, parses it and stores it in the internal cache of SQL Server and returns a reference number which is the Handle to the newly created xml document.

This handle number is used as a reference.
