Question
xquery join from SQL Select
Hi
I am just starting to work with "FOR XML" queries. I have the following SQL statement in MSSQL 2005 and am unable to get any data in to the Item2 node of the XML.
SELECT (
SELECT Table1.FieldX, Table2.FieldY
FROM Table1 Left JOIN
Table2 ON Table1.ID = Table2.ID
WHERE Table1.FieldZ='abc'
for xml auto, type).query (
'<xmlDemo>
{for $sp in /*
return
<Items>
<Item1>{data($sp/@FieldX)}
<Item2>{data($sp/@FieldY)}
</Items>}
</xmlDemo>')
So far I have tried "{for $sp in /FieldX, or $sp in /FieldY" , selecting the entire Select (..) as _derived with {for $sp in /_derived
all to no avail. I have also attempted to create an XQuery join but I am not sure the syntax was correct.
I know it must be something to do with joins but I am not sure where to go.
Any help would be much appreciated.
Thanks
