SQL Query values out of XML using - sql-server

Question

I can't figure out what I'm doing wrong. I have XML stored in a table column as text. I'm taking the ID, and the XML text and querying it into a temp table that stores the XML as XML type.
Each Order in the XML has multiple licenses in it that I need to pull out and create a new table with OrderID and License ID. But I can't tell what I'm doing wrong.
So, I'm trying to start basic but I can't seem to even just get the Account Info from the first Node.
The XML looks like this:
<ns1:OrderFromCRM xmlns:ns1="http://company.com/licensing/neworder/v2">
<ns1:AccountInfo Name="Company Name" AccountId="A012345" />
<ns1:OrderInfo CRMOrderId="S147360" Date="2/23/2017 12:00:00 AM" ffEmail="emailaddress.#gmail.com" >
<ns1:Licensing>
<ns1:Foundations>
<ns1:Foundation LicenseId="L012345678" Action="Create" Environment="Production" Type="Enterprise">
<Metadata>
<AllowedInstances>999</AllowedInstances>
</Metadata>
</ns1:Foundation>
<ns1:Foundation LicenseId="L012345698" Action="Create" Environment="Production" Type="Enterprise">
<Metadata>
<AllowedInstances>999</AllowedInstances>
</Metadata>
</ns1:Foundation>
</ns1:Foundations>
<ns1:Licenses Type="Create">
<ns1:License LicenseId="L0123451234" ProductFamily="Fam1" Product="EStudio" LicenseType="Perpetual" StartDate="2017-02-23" ExpiryDate="2017-12-18" MaintenanceExpiryDate="2017-12-18">
<ns1:Capabilities>
<ns1:Capability Name="T1" />
<ns1:Capability Name="Q1" />
<ns1:Capability Name="B1" />
</ns1:Capabilities>
</ns1:License>
<ns1:License LicenseId="L333356675" ProductFamily="Fam1" Product="EStudio" LicenseType="Perpetual" StartDate="2017-02-23" ExpiryDate="2017-12-18" MaintenanceExpiryDate="2017-12-18">
<ns1:Capabilities>
<ns1:Capability Name="T1" />
<ns1:Capability Name="Q1" />
<ns1:Capability Name="B1" />
</ns1:Capabilities>
</ns1:License>
The SQL I wrote is:
CREATE TABLE #demoData
(
ActivationCode NVARCHAR(100) NOT NULL,
OrderXMLText XML
)
SELECT OrderId, OrderXMLText.value('(/OrderFromCRM/AccountInfo)[1]', 'varchar(30)')
FROM #DEMODATA
I mentioned I need the OrderID and the LicenseId but even with this, I can't get anything. Am I on right track? First, what am I missing? Second, once this is formatted correctly, how do I get the nested LicenseIds in the XML?
Thanks so much for any help. I've been trying to make this work for a couple days

Answer 1

You’re missing the namespace so the query isn’t matching the xml, therefore it doesn’t find the elements you’re querying.
Add
;WITH XMLNAMESPACES

Answer 2

Assuming you have a complete, valid XML document in your table (the one you're showing is lacking several closing tags), then you could try something like this:
;WITH XMLNAMESPACES('http://company.com/licensing/neworder/v2' AS ns1)
SELECT
ActivationCode,
CRMOrderId = XC.value('#CRMOrderId', 'varchar(100)'),
FoundationsLicenseId = xcf.value('#LicenseId', 'varchar(50)'),
LicensesLicenseId = xcl.value('#LicenseId', 'varchar(50)')
FROM
#demoData
CROSS APPLY
OrderXMLText.nodes('/ns1:OrderFromCRM/ns1:OrderInfo') AS XT(XC)
CROSS APPLY
XC.nodes('ns1:Licensing/ns1:Foundations/ns1:Foundation') AS XTF(XCF)
CROSS APPLY
XC.nodes('ns1:Licensing/ns1:Licenses/ns1:License') AS XTL(XCL)
First of all, you need to include and respect the XML namespace in your XQuery - that's what I do with the WITH XMLNAMESPACES() directive.
Next, you need to use .nodes() to get a list of XML fragments for each <OrderInfo> node, which is located below the root node (<OrderFromCRM>). This is the first CROSS APPLY. This returns a list of XML fragments, one for each <OrderInfo> node.
Then you need to reach into these XML fragments, and again use CROSS APPLY with the .nodes() function to get a list of the <Foundation> elements (contained in the <Licensing>/<Foundations> subtree to get the license Id's from those nodes. In addition, you need a second CROSS APPLY to get all the <License> subnodes under <Licensing>/<Licenses> to get those LicenseId attributes.
That should return an output something like:
Hope this helps you some!
