Question

I have an xml file which is given as an input to a stored procedure in SQL Server. I have a table which has columns element name and parent id. The root element parent id is 0 the first element parent id is 1and so on. How do I achieve this?

I have several complex types in my xml

<VoyageOrderMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="voyage.xsd">
    <MessageHeader>
            <MessageId>ID</MessageId>
            <MessageDate>2009-11-01T11:42:07.414+03:00</MessageDate>
            <MessageTypeVersion>Version</MessageTypeVersion>
            <SenderId>SI</SenderId>

                <ReceiverAddress></ReceiverAddress>
                </ReceiverDetails>
    </MessageHeader>
    <VoyageOrder>
            <VoyageID>RG-FUW-001</VoyageID>
            <Amendment>4</Amendment>

            <Passage>
                <PassageNumber>1</PassageNumber>
                <PassageType>Laden</PassageType>
                <DeparturePortName>Ras Laffan</DeparturePortName>
                <DeparturePortCode>RLF</DeparturePortCode>
                <DepartureTime>2009-10-06T19:06:00.000+03:00</DepartureTime>

            </Passage>

Example output

elementname parent id column
------------------------------
voyageorder   0             1
messageheader 1           2
messageid     2           3
etc

Any help is appreciated

Looks like the Edge Table Format returned by OPENXML is something you could use.

declare @idoc int

exec sp_xml_preparedocument @idoc output, @xml

select *
from openxml(@idoc, '*')

exec sp_xml_removedocument @idoc
