I think the problem is around the namespaces. I have updated the code to the following and i think it works how you need it to:

-- DROP the previous SCHEMA COLLECTION

IF EXISTS(

SELECT * FROM sys.xml_schema_collections

WHERE name = 'Lab1'

) BEGIN

DROP XML SCHEMA COLLECTION Lab1

END

GO

-- CREATE the SCHEMA COLLECTION with the updated

-- definition.

CREATE XML SCHEMA COLLECTION Lab1 AS

'<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="myNS" xmlns:ns="myNS">

The changes that i made were:

1. prefixed type on homePhone to: type="ns:emptyorint"

2. changed simpleType to use regular expression to validate numbers only

3. changed namespaces on xml example

This seems to allow nil values and only numbers in the homePhone node.

Hope this helps or gets you closer.

excellent. thank you. so it appears that I should use type string and validate using regular expression as I just can't get non string data types to allow nulls.

Thanks again, I've been trying to get this for two days.

No problem.

The main issue was around the namespaces and not the data type. I used the string type with a reg ex in my example because of habit with working with phone number type data and the non-numeric characters they invariably contain. 🙂

The following code uses the xsd:int type instead:

-- DROP the previous SCHEMA COLLECTION

IF EXISTS(

SELECT * FROM sys.xml_schema_collections

WHERE name = 'Lab1'

) BEGIN

DROP XML SCHEMA COLLECTION Lab1

END
