In my SQL 2008 database table, I have one column name AUTHOR that contains XML data. The XML is not well formed and has data like below

<Author>
<ID>172-32-1176</ID>
<LastName>White</LastName>
<FirstName>Johnson</FirstName>
<Address>
<Street>10932 Bigge Rd.</Street>
<City>Menlo Park</City>
<State>CA</State>
</Address>
</Author>

Some XML have all of above data and some have just one tag.

<ID>172-32-1176</ID>

I want to write query that returns me a column as identiry.
I tried using AUTHOR.query(‘data(/Author/ID)’) as identity but it fails when XML does not have Author node.

Thanks,
Vijay

    Have you tried something like /Author/ID|/ID ? i.e. try for the first scenario, and with no match, the second ?

    (note that the | operator is a set union operator, as described here)
