XML joining Nested resultsets
ccot...@yahoo.com
<Client>
<Report id = "01">
<Item id = "01" Description = ",a.mdfbnelt;yuk" </Item>
<Item id = "02" Description = "AAAAA;yuk" </Item>
<Item id = "03" Description = "XXXXX" </Item>
</Report>
<Report id = "02">
<Item id = "01" Description = ",ABCDEF" </Item>
<Item id = "02" Description = "JHIKLM" </Item>
<Item id = "03" Description = "OPQRST" </Item>
</Report>
</Client>
I would like to extract and insert data into the following file
Table MyTable(Client, Report_id, Item_id, Description)
So I created the following query
SELECT
extractValue(VALUE(x), '/Client/@id')) Client,
extractValue(VALUE(d), '/Report/@id') Report,
extractValue(VALUE(e), '/Item/@id') Description,
extractValue(VALUE(e), '/Item/@Description) Description
FROM XMLDOC2 x,
TABLE(xmlsequence(extract(VALUE(x), '/Client/Report'))) d,
TABLE(xmlsequence(extract(VALUE(x), '/Client/Report/Item'))) e
But I get the cartesian product of the reports and the items. I would
like to get the items related to a reports AND the report id on the
same line. If it is not possible, I would like to filter out the items
belonging to report; some kind of where clause.
Anybody has an idea?
Thank you,
CCote
