Question

I have the following XML:

<query>
  <param weight="0.3">
    <item type="1" low="18" hi="20" pos="1" />
    <item type="1" low="220" hi="220" pos="0" />
  </param>
  <param weight="0.7">
    <item type="2" low="5" hi="5" pos="1" />
  </param>
</query>

I want it to result in the following data set:

1   0.3 1   18  20  1
2   0.3 1   220 220 0
3   0.7 2   5   5   1

ROW_NUMBER() would make the row number. I’m only getting the first row (item[1]), but not the others. If I remove the ‘[1]’, I get a “singleton error”. How do I write this?

This is what I have so far:

SELECT  x.node.value('@weight', 'float') As [Weight],
        x.node.value('(item/@type)[1]', 'int') AS [Type],
        x.node.value('(item/@low)[1]', 'float') AS Low,
        x.node.value('(item/@hi)[1]', 'float') AS Hi,
        x.node.value('(item/@pos)[1]', 'bit') AS Pos
FROM    @Input.nodes('/query//*') AS x(node)

Answer 1

I figured it out with OPENXML:

INSERT  INTO @ref
SELECT  *
FROM    OPENXML (@idoc, '/query/param/item', 2)
WITH    ([Weight]   float   '../@weight',
        ParamType   int     '@type',
        Low         float   '@low',
        Hi          float   '@hi',
        Pos         bit     '@pos')
