Question

How do I select data from a XML column in a SQL Server table in SQL Server Management Studio?
I would like to get this result:

<quantity unit="BOX">1.0</quantity>

</product-lineitem>
<product-lineitem>

<quantity unit="PCS">1.0</quantity>

I have the last problem (i hope) ;)
How to return data from product-lineitems. I mean: Quantity, Quantity-unit
Im trying like that: But it's return duplicate rows :(
WITH XMLNAMESPACES(DEFAULT N'www address')
SELECT
o.value(N'(current-order-no/text())[1]',N'varchar(10)') AS OrderNo
,n.value(N'(quantity/text())[1]',N'varchar(10)') AS Qty
,u.value(N'#unit',N'varchar(10)') AS Unit
FROM
dbSupply.dbo.MyXmlTable t
CROSS APPLY
t.XMLData.nodes(N'/orders/order') A(o)
OUTER APPLY
A.o.nodes(N'product-lineitems/product-lineitem') B(n)
OUTER APPLY
A.o.nodes(N'product-lineitems/product-lineitem/quantity') C(u)

You can try it like this:
DECLARE #mockupTable TABLE(ID INT IDENTITY, YourXml XML);
INSERT INTO #mockupTable VALUES
(N'<orders xmlns="www address">
<order order-no="000001">
<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>
<customer>
<customer-name>Jonh Smith</customer-name>
<customer-email>JonhSmith#gmail.com</customer-email>
</customer>
</order>
</orders>');
WITH XMLNAMESPACES(DEFAULT N'www address')
SELECT o.value(N'#order-no',N'varchar(10)') AS OrderNo
,o.value(N'(order-date/text())[1]',N'date') AS OrderDate
,o.value(N'(created-by/text())[1]',N'varchar(100)') AS CreatedBy
,o.value(N'(original-order-no/text())[1]',N'varchar(10)') AS OriginalOrderNo
,o.value(N'(currency/text())[1]',N'varchar(10)') AS Currency
,o.value(N'(taxation/text())[1]',N'varchar(10)') AS Taxation
,o.value(N'(invoice-no/text())[1]',N'varchar(10)') AS InvoiceNo
,o.value(N'(customer/customer-name/text())[1]',N'varchar(100)') AS CustomerName
,o.value(N'(customer/customer-email/text())[1]',N'varchar(100)') AS CustomerEMail
FROM #mockupTable t
CROSS APPLY t.YourXml.nodes(N'/orders/order') A(o);
Be aware of the need to declare your (default) name space correctly. I used .nodes() because "orders" sounds like plural. Your sample includes just one order, but there might be more...
UPDATE: Your additional "notes"
In any case of 1:n relationship (many nodes related to one partent node), you need .nodes() in order to get each fragment as a separate row:
WITH XMLNAMESPACES(DEFAULT N'www address')
SELECT o.value(N'#order-no',N'varchar(10)') AS OrderNo
,o.value(N'(order-date/text())[1]',N'date') AS OrderDate
,o.value(N'(created-by/text())[1]',N'varchar(100)') AS CreatedBy
,o.value(N'(original-order-no/text())[1]',N'varchar(10)') AS OriginalOrderNo
,o.value(N'(currency/text())[1]',N'varchar(10)') AS Currency
,o.value(N'(taxation/text())[1]',N'varchar(10)') AS Taxation
,o.value(N'(invoice-no/text())[1]',N'varchar(10)') AS InvoiceNo
,o.value(N'(customer/customer-name/text())[1]',N'varchar(100)') AS CustomerName
,o.value(N'(customer/customer-email/text())[1]',N'varchar(100)') AS CustomerEMail
,n.value(N'(created-by/text())[1]',N'nvarchar(100)') AS Note_CreatedBy
,n.value(N'(creation-date/text())[1]',N'datetime') AS Note_CreatedBy
,n.value(N'(subject/text())[1]',N'nvarchar(100)') AS Note_CreatedBy
,n.value(N'(text/text())[1]',N'nvarchar(1000)') AS Note_CreatedBy
FROM #mockupTable t
CROSS APPLY t.YourXml.nodes(N'/orders/order') A(o)
OUTER APPLY A.o.nodes(N'notes/note') B(n);
The last line will pick the current order and pass it into .nodes(). This will return a derived set with one row per <note>.

You can use OPENROWSET
CREATE DATABASE MyXmlDataBase
GO
USE MyXmlDataBase
GO
CREATE TABLE MyXmlTable
(
Id INT IDENTITY PRIMARY KEY,
Name NVARCHAR(50),
XMLData XML
)
INSERT INTO MyXmlTable(Name, XMLData)
SELECT CONVERT(XML, BulkColumn) AS BulkColumn, GETDATE()
FROM OPENROWSET(BULK 'D:\MyXmlFileOnDisk.xml', SINGLE_BLOB) AS x;
SELECT * FROM MyXmlTable
