Not sure if this question belongs here or in the XML forums.

I've been reading everywhere that SQL Server 2008 has made time zones optional on the dates in an XML.

I am working with SQL Server 2008 R2. When I enter a date (without the time, just date) in an xs:date field without the Z, it fails XML schema validation, it works fine if I add the Z or any other time zone "2005-08-31+08:00" works too.

Can you script a repro? This works fine for me:



DECLARE @schema xml =

    N'<?xml version = "1.0"?>

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

        <xsd:element name="theDate">

            <xsd:simpleType>

                <xsd:restriction base="xsd:date">

            </xsd:restriction>

            </xsd:simpleType>

        </xsd:element>

    </xsd:schema>

    ';

CREATE XML SCHEMA COLLECTION dbo.TestSchemaCollection AS @schema;

GO

DECLARE @x xml (DOCUMENT dbo.TestSchemaCollection);

SET @x = N'<?xml version = "1.0"?><theDate>2011-07-11</theDate>';

SELECT @x.value('theDate', 'date');

GO

DROP XML SCHEMA COLLECTION dbo.TestSchemaCollection;

I ran your script in 4 environments and it only passes in 1 without the Z, it passes all with the Z.

Can this be server version issue?

10.0.2734 Fails

10.0.2757 Fails

10.0.4000 Passes

10.0.5500 Fails

Ok, looks like the compatibility level of some databases are set to 2005, found the issue, thanks!

Could be, I tested on 10.50.2789 and a 2012 build. Odd that 2008 SP3 has moved backward w.r.t SP2. I've read various things about xml dates/times over the years, and certainly the ISO format is a good practice (CONVERT style 127) though the Z shouldn't really be required, in my opinion anyway.
