我的情况是这样的(简化):
DECLARE @period XML = (
SELECT
'2012' 'period'
FOR XML PATH(''), ROOT ('survey'))
DECLARE @persons XML = (
SELECT
Person.Name 'users/person'
FROM Person
FOR XML PATH(''), ROOT ('company'))
SET @persons.modify('insert sql:variable("@period") as first into (/company)[1]')
SELECT @persons
这给了我这样的XML:
<company>
<survey>
<period>2012</period>
</survey>
<users>
<person>Dubach</person>
</users>
<users>
<person>Pletscher</person>
</users>
...
现在我需要将XML模式添加到根节点,如下所示:
<company xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.mydomain.com/xmlns/bla/blabla/myschema.xsd" xmlns="http://www.mydomain.com/xmlns/bla/blabla">
<survey>
<period>2012</period>
</survey>
<users>
<person>Dubach</person>
</users>
<users>
<person>Pletscher</person>
</users>
...
在SELECT语句之前Microsoft says I have to use WITH XMLNAMESPACES但在我的情况下不起作用。
如何添加这些xmlnamespaces?
答案 0 :(得分:4)
从选择中拆分声明,然后将with xmlnamespaces
用作described。
DECLARE @persons XML
;with xmlnamespaces (
'http://www.mydomain.com/xmlns/bla/blabla' as ns,
'http://www.w3.org/2001/XMLSchema-instance' as xsi
)
select @persons = (
select
Person.Name as 'ns:users/person'
FROM Person
FOR XML PATH(''), ROOT ('company')
)
set @persons.modify('insert ( attribute xsi:schemaLocation {"http://www.mydomain.com/xmlns/bla/blabla/myschema.xsd"}) into (/company)[1]')

我找到了一个在这里添加所有命名空间的解决方案:

显然它不是非常“漂亮”的风格,但在我的情况下,它有效,我还没有找到另一个有效的解决方案。

DECLARE @period XML = (
SELECT
'2012' 'period'
FOR XML PATH(''), ROOT ('survey'))
DECLARE @persons XML = (
SELECT
Person.Name 'users/person'
FROM Person
FOR XML PATH(''), ROOT ('company'))
SET @persons.modify('insert sql:variable("@period") as first into (/company)[1]')
-- SOLUTION
SET @persons = replace(cast(@persons as varchar(max)), '<company>', '<company xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.mydomain.com/xmlns/bla/blabla/myschema.xsd" xmlns="">')
SELECT @persons
