From your question there’s one thing not clear: The naming of the output columns.
In your expected output they are named like their attribute-id
. But in your comments it sounds, like you are picking the first 4 attributes and you want to omit the rest.
I want to show two approaches, pick the one you like more:
DECLARE @mockupTable TABLE(ID INT IDENTITY, YourXml XML);
INSERT INTO @mockupTable VALUES
(N'<orders xmlns="www address">
<order>
<order-date>2019-09-05</order-date>
<created-by>storefront</created-by>
<original-order-no>000001</original-order-no>
<currency>USD</currency>
<taxation>gross</taxation>
<invoice-no>0099999</invoice-no>
<custom-attributes>
<custom-attribute attribute-id="t01">c01</custom-attribute>
<custom-attribute attribute-id="t02">c02</custom-attribute>
<custom-attribute attribute-id="t03">c03</custom-attribute>
<custom-attribute attribute-id="t04">c04</custom-attribute>
</custom-attributes>
</order>
</orders>');
–This query will use the attribute-id
to pick the corresponding attribute.
–We can savely return this with the same name
–If your XML does not have the corresponding attribute, there will be a NULL value
WITH XMLNAMESPACES(DEFAULT 'www address')
SELECT o.value('(order-date/text())[1]','date') OrderDate
--As in your other questions
,o.value('(custom-attributes/custom-attribute[@attribute-id="t01"]/text())[1]','varchar(100)') AS t01
,o.value('(custom-attributes/custom-attribute[@attribute-id="t02"]/text())[1]','varchar(100)') AS t02
,o.value('(custom-attributes/custom-attribute[@attribute-id="t03"]/text())[1]','varchar(100)') AS t03
,o.value('(custom-attributes/custom-attribute[@attribute-id="t04"]/text())[1]','varchar(100)') AS t04
FROM @mockupTable t
CROSS APPLY t.YourXml.nodes('/orders/order') A(o);
–This one is easier. It will pick just the first four attributes, no matter what id they have.
WITH XMLNAMESPACES(DEFAULT 'www address')
SELECT o.value('(order-date/text())[1]','date') OrderDate
--As in your other questions
,o.value('(custom-attributes/custom-attribute[1]/text())[1]','varchar(100)') AS ca1
,o.value('(custom-attributes/custom-attribute[2]/text())[1]','varchar(100)') AS ca2
,o.value('(custom-attributes/custom-attribute[3]/text())[1]','varchar(100)') AS ca3
,o.value('(custom-attributes/custom-attribute[4]/text())[1]','varchar(100)') AS ca4
FROM @mockupTable t
CROSS APPLY t.YourXml.nodes('/orders/order') A(o);
