SQL - default blank namespace

I have a relation that has an XML column storing data in the following structure

<Report id="b5d9b8da-7af4-4257-b825-b28af91dd833">
    <CreatedDate>04-12-2012</CreatedDate>
    <LastUpdated>04-12-2012</LastUpdated>
    <Reference>abc123</Reference>
</Report>

I am writing a stored procedure to retrieve all reports and join them and transfer them to the root node called reports. So far I have the following:

WITH XMLNAMESPACES(DEFAULT 'http://www.defaultnamespace.com/1.0')
        SELECT
    @Xml = 
    (

            SELECT
                (
                    SELECT xml.query('.')
                    FROM
                        [database].[Reports]
                    WHERE
                        ClientId = @clientId
                    FOR XML PATH(''),
                    TYPE
                )
            FOR XML PATH('Reports'),
            TYPE
        )

As long as this returns all reports in the correct format, there is an empty default namespace in the report element, for example the following:

<Reports xmlns="http://www.defaultnamespace.com/1.0">
<Report  xmlns="" id="b5d9b8da-7af4-4257-b825-b28af91dd833">
    <CreatedDate>04-12-2012</CreatedDate>
    <LastUpdated>04-12-2012</LastUpdated>
    <Reference>abc123</Reference>
</Report>
</Reports>

Can someone explain a suitable way to exclude a namespace in a report element?

Any help really appreciated by the guys :)

Your problem is that the column was not saved with the default namespace "http://www.defaultnamespace.com/1.0".

, - NS = "", name = Report.

SQL Server .

,

, XML, , , " , , " http://www.defaultnamespace ". com/1.0",

AFAIK, ( , !). , , nvarchar(max) , .

0

, , , XQuery XML.

SQL Server WITH XMLNAMESPACES XQuery, ...

if object_id(N'Reports') is not null drop table [Reports];
go
create table [Reports] (
    [ClientId] int not null,
    [xml] [xml] not null
)
go
insert [Reports] ([ClientID], [xml])
    values (1, N'<Report id="b5d9b8da-7af4-4257-b825-b28af91dd833">
    <CreatedDate>04-12-2012</CreatedDate>
    <LastUpdated>04-12-2012</LastUpdated>
    <Reference>abc123</Reference>
</Report>');
go
declare @clientId int = 1
select  (
    select [xml].query('/*:Report')
    from [Reports]
    where ClientId = @clientId
    for xml path('Reports'), type
    ).query('declare default element namespace "http://www.defaultnamespace.com/1.0";
    for $x in /*:Reports return
        <Reports>
        {
            for $y in $x/*:Report return
            <Report>
                {attribute id {$y/@id}}
                {element CreatedDate {$y/*:CreatedDate/text()}}
                {element LastUpdated {$y/*:LastUpdated/text()}}
                {element Reference {$y/*:Reference/text()}}
            </Report>
        }
        </Reports>')
go

XML:

<Reports xmlns="http://www.defaultnamespace.com/1.0">
  <Report id="b5d9b8da-7af4-4257-b825-b28af91dd833">
    <CreatedDate>04-12-2012</CreatedDate>
    <LastUpdated>04-12-2012</LastUpdated>
    <Reference>abc123</Reference>
  </Report>
</Reports>
