The below function creates an XML document that is then written to disk.  Also below is an T-SQL command that converts part of the XML document into an SQL table.  It all works.  

QUESTION:  Can the step of writing the XML document to disk be skipped and the XML document object be sent directly to the T-SQL statement that is sent to SQL 2008?
    Public Function xCMP() As XDocument

        Return _
         <?xml version="1.0"?>
         <CMPDocument>
             <Title>EPOWERdoc - CMP Document</Title>
             <Client>
                 <DateProcessed><%= Dt2Db(Now()) %></DateProcessed>
                 <CliNo><%= Clino %></CliNo>
                 <CliServerName><%= CliServerName %></CliServerName>
                 <RAMTotal><%= RAMTotal %></RAMTotal>
                 <RAMSQL><%= RAMSQL %></RAMSQL>
                 <LastFDBUpdate><%= LastFDBUpdate %></LastFDBUpdate>
             </Client>
             <CMPData>
                 <%= xDiskDrives %>
                 <%= xVolume %>
                 <%= xExecutables %>
                 <%= xEPDApplicationErrors %>
                 <%= xEventLog %>
             </CMPData>
         </CMPDocument>
    End Function

Hi,

Since SQL has an xml data type, you may add it to the procedure's parameters and then directly pass an xml to the sp instead of writting it to the disk.

For calling it through your program you may check the following link:
