我正在一个项目中,我正在编写的存储过程正在生成XML格式的输出。我想向“主”节点添加名称空间,并向子节点添加JSON ValueType。下面是我的代码:
--- Fake tables in stored procedure
create table #Cdetails(cid int, cidtype varchar(5), name varchar(5), age int)
insert into #Cdetails
values (1001, 'N', 'John', 12), (1002, 'U', 'Rick', 19),
(1003, 'N', 'Diane', 25), (1004, 'N', 'Kippy', 26)
--Output of stored procedure
create table #final(cid int, cidtype varchar(5), xml_data xml)
insert into #final
select
cid = c1.cid,
cidtype = c1.cidtype,
case
when c1.cidtype = 'N'
then (select
'Value/@json:ValueType'='Number',
ID = cd1.cid,
details = (select
cd1.name, cd1.age
for xml path(''), type)
from
#Cdetails cd1
where
cd1.cid = c1.cid
for xml path('Main'))
when c1.cidtype = 'N'
then (select
ID = cd1.cid,
details = 'Null'
from
#Cdetails cd1
where
cd1.cid = c1.cid
for xml path('Main'))
end as 'xml_data'
from
#Cdetails c1
;WITH XMLNAMESPACES ('http://www.integround.com/json' as json)
SELECT *
FROM #final
WHERE xml_data IS NOT NULL
FOR XML PATH('Main')
drop table #Cdetails, #final
在此过程中,基于CIDType条件生成XML。所以我当前的输出是:
我想将名称空间添加到“主”节点,并将JSON属性添加到子节点。
错误
FOR XML列名称“ Value / @ json:ValueType”缺少XML名称空间前缀“ json”声明。

有帮助吗?!
答案 0 :(得分:1)
XML Construction可以帮助您吗?
DECLARE @cdetails table(
cid INT, cidtype VARCHAR(5), name VARCHAR(5), age INT
);
INSERT INTO @cdetails VALUES
(1001, 'N', 'John', 22), (1002, 'U', 'Rick', 21),
(1003, 'N', 'Diane', 25), (1004, 'N', 'Kippy', 26);
SELECT
cid, cidtype,
CAST('' AS XML).query('
<Main xmlns:json="http://www.samplenamespace.com/json">
<ID json:ValueType="Number">{sql:column("cid")}</ID>
{
if( sql:column("cidtype")="N" ) then
<details>
<name>{sql:column("name")}</name>
<age>{sql:column("age")}</age>
</details>
else <details>Null</details>
}
</Main>
')
FROM @cdetails;
