Querying SQL for grouped data and receiving it in BizTalk? - sql

Question

I have a query that returns data organized by group. I am wanting to have them come out in a grouped XML similar to the format below. I am planning to pass it in as a XML message into BizTalk using the WCF-SQL port adapter.
Data:
ID GroupID Item ID FileName
1 1 1 File001.txt
2 1 2 File001.txt
3 2 3 File002.txt
4 2 4 File002.txt
5 2 5 File002.txt
6 3 6 File003.txt
7 3 7 File003.txt
8 null 8 File004.txt
9 null 9 File005.txt
XML Ouput (input to BizTalk)
<GroupInfo ID=1 FileName=File001.txt>
<Items>
<Item ID=1 />
<Item ID=2 />
</Items>
</GroupInfo>
<GroupInfo ID=2 FileName=File002.txt>
<Items>
<Item ID=3 />
<Item ID=4 />
<Item ID=5 />
</Items>
</GroupInfo>
<GroupInfo ID=3 FileName=File003.txt>
<Items>
<Item ID=6 />
<Item ID=7 />
</Items>
</GroupInfo>
<GroupInfo FileName=File004.txt>
<Items>
<Item ID=8 />
</Items>
</GroupInfo>
<GroupInfo FileName=File005.txt>
<Items>
<Item ID=9 />
</Items>
</GroupInfo>
I'm not sure what to do to get the output in the required format. Please help.

To accomplish this, you would have to use FOR XML results from the Stored Procedure.
All documented here: http://technet.microsoft.com/en-us/library/ms178107.aspx
In this case, you might find it easier to join the table to itself on GroupID as FOR XML AUTO will automatically create child records for the joined rows.
