Question

I need further assistance with extracting records from XML and loading it into a SQL Server table.

I have this as my @xml:

<admin submitter_id="login0" effective_date="mm/dd/yyyy">
<rec effected_id="login1" adjustment="100.00" type="foo">
<reason reason_id="1" />
<reason reason_id="2" />
</rec>
<rec effected_id="login2" adjustment="50.00" type="bar">
<reason reason_id="3" />
</rec>
</admin>

I need this from a result set:

login0, login1, mm/dd/yyyy, 100.00, foo, 1
login0, login1, mm/dd/yyyy, 100.00, foo, 2
login0, login2, mm/dd/yyyy, 50.00, bar, 3

Does that make sense? The adjustment to the reason_id is one to many. I have figured out how to extract all the values except for the second line. I can only obtain the first reason_id and then it proceeds to the next record. I think this can be beaten with a CROSS APPLY but I cannot get it to work. Please help!

oh, I may also have received bogus XML. So if that’s wrong, please tell me!

How about something like

DECLARE @Xml XML

SELECT @Xml = '<admin submitter_id="login0" effective_date="mm/dd/yyyy"> 
<rec effected_id="login1" adjustment="100.00" type="foo"> 
<reason reason_id="1" /> 
<reason reason_id="2" /> 
</rec> 
<rec effected_id="login2" adjustment="50.00" type="bar"> 
<reason reason_id="3" /> 
</rec> 
</admin>'

SELECT  @Xml,
        A2.B.value('(../../@submitter_id)[1]','VARCHAR(50)'),
        A2.B.value('(../@effected_id)[1]','VARCHAR(50)'),
        A2.B.value('(../../@effective_date)[1]','VARCHAR(50)'),
        A2.B.value('(../@adjustment)[1]','FLOAT'),
        A2.B.value('(../@type)[1]','VARCHAR(50)'),
        A2.B.value('(@reason_id)[1]','INT')
FROM    @XML.nodes('//admin/rec/reason')  A2(B)
