您好我需要在sql中提供以下帮助:
我需要以这种格式创建一个xml文件
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:001.002.001.04">
<FIToFIPmtStsRpt>
<GrpHdr>
<MsgId></MsgId>
</GrpHdr>
<OrgnlGrpInfAndSts>
<OrgnlMsgId />
</OrgnlGrpInfAndSts>
</FIToFIPmtStsRpt>
</document>
目前我有一个包含主要信息的变量,我建立了信息之间的信息(认为grphdr可以多次插入到主xml中,使用不同的信息)
declare @xml xml='<Document
xmlns="urn:iso:std:iso:20022:tech:xsd:001.002.001.04">
<FIToFIPmtStsRpt>
</FIToFIPmtStsRpt>
</Document>
'
declare @xmlgrp xml='<GrpHdr>
<MsgId></MsgId>
</GrpHdr>'
--here i do some code to fill msgid
然后我将grphdr添加回主xml
SET @xml.modify
('declare namespace a= "urn:iso:std:iso:20022:tech:xsd:001.002.001.04";
insert sql:variable("@xmlgrp")
into (a:Document/a:FIToFIPmtStsRpt)[1]')
select @xml
我需要找出顶级文件格式,但现在发生的是以下内容
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:001.002.001.04">
<FIToFIPmtStsRpt>
<GrpHdr xmlns="">-- i need this xmlns tag out
<MsgId />
</GrpHdr>
</FIToFIPmtStsRpt>
</Document>
不知怎的,我需要xml中的空xmlns标签。我无法转换为varchar(max)以删除,因为我们的数据库已将变量限制为8000个字符 我的xml可以增长到8000以上。 1个文件中可以有多个grphdr或OrgnlGrpInfAndSts
table: lim_Live_Inbound
lim_msg_id | lim_request_transaction_id | client_name
------------------------------------------------------
021/00210006/20160225/000002 | 00012016-02-25000000023 | Mr Piet
021/00210006/20160225/000002 | 00012016-02-25000000022 | Mrs Name
必须像这样生成
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:001.002.001.04">
<FIToFIPmtStsRpt>
<GrpHdr>
<MsgId>021/00210006/20160225/000002</MsgId>
</GrpHdr>
<OrgnlGrpInfAndSts>
<OrgnlMsgId>00012016-02-25000000023</OrgnlMsgId>
<name>Mr Piet</name>
</OrgnlGrpInfAndSts>
<OrgnlGrpInfAndSts>
<OrgnlMsgId>00012016-02-25000000022</OrgnlMsgId>
<name>Mrs Name</name>
</OrgnlGrpInfAndSts>
</FIToFIPmtStsRpt>
</document>
这就是我尝试插入xml方式的原因。如果有人能以更好的方式帮助我,那将非常感激。
答案 0 :(得分:4)
这种解决方法实际上仍然没有用处。命名空间xmlns=""
被视为* 内的所有内容都不在命名空间内 ...您可以将结果转换为NVARCHAR(MAX)
并使用REPLACE
来摆脱xmlns=""
。然后,您可以将字符串重新转换为XML
。对微软的羞辱,10(!!)岁的问题(见下面的链接)仍未解决。请去那里投票!
DECLARE @lim_Live_Inbound TABLE(lim_msg_id VARCHAR(100),lim_request_transaction_id VARCHAR(100),client_name VARCHAR(100));
INSERT INTO @lim_Live_Inbound VALUES
('021/00210006/20160225/000002','00012016-02-25000000023','Mr Piet')
,('021/00210006/20160225/000002','00012016-02-25000000022','Mrs Name');
DECLARE @nestedXMLs TABLE(MsgId VARCHAR(100),nestedXML XML);
WITH GrpMsg AS
(
SELECT DISTINCT lim_msg_id AS MsgId
FROM @lim_Live_Inbound
)
INSERT INTO @nestedXMLs
SELECT MsgId
,(
SELECT innerTbl.lim_request_transaction_id AS OrgnlMsgId
,innerTbl.client_name AS name
FROM @lim_Live_Inbound AS innerTbl
WHERE innerTbl.lim_msg_id=GrpMsg.MsgId
FOR XML PATH('OrgnlGrpInfAndSts'),TYPE
)
FROM GrpMsg;
WITH XMLNAMESPACES(DEFAULT 'urn:iso:std:iso:20022:tech:xsd:001.002.001.04')
,GrpMsg AS
(
SELECT DISTINCT lim_msg_id AS MsgId
FROM @lim_Live_Inbound
)
SELECT GrpMsg.MsgId AS [GrpHdr/MsgId]
,n.nestedXML AS [node()]
FROM GrpMsg
INNER JOIN @nestedXMLs AS n ON GrpMsg.MsgId=n.MsgId
FOR XML PATH('FIToFIPmtStsRp'),ROOT('Document')
结果
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:001.002.001.04">
<FIToFIPmtStsRp>
<GrpHdr>
<MsgId>021/00210006/20160225/000002</MsgId>
</GrpHdr>
<OrgnlGrpInfAndSts xmlns="">

<name>Mr Piet</name>
</OrgnlGrpInfAndSts>
<OrgnlGrpInfAndSts xmlns="">

<name>Mrs Name</name>
</OrgnlGrpInfAndSts>
</FIToFIPmtStsRp>

您使用CAST(REPLACE(CAST(TheXMLHere AS NVARCHAR(MAX)),' xmlns=""','') AS XML)
来摆脱错误的空命名空间....
这是重复命名空间 - 但这在语法上是正确的,但很烦人(在这里阅读:https://connect.microsoft.com/SQLServer/feedback/details/265956/suppress-namespace-attributes-in-nested-select-for-xml-statements)
DECLARE @lim_Live_Inbound TABLE(lim_msg_id VARCHAR(100),lim_request_transaction_id VARCHAR(100),client_name VARCHAR(100));
INSERT INTO @lim_Live_Inbound VALUES
('021/00210006/20160225/000002','00012016-02-25000000023','Mr Piet')
,('021/00210006/20160225/000002','00012016-02-25000000022','Mrs Name');
WITH XMLNAMESPACES(DEFAULT 'urn:iso:std:iso:20022:tech:xsd:001.002.001.04')
,GrpMsg AS
(
SELECT DISTINCT lim_msg_id AS MsgId
FROM @lim_Live_Inbound
)
SELECT MsgId AS [GrpHdr/MsgId]
,(
SELECT innerTbl.lim_request_transaction_id AS OrgnlMsgId
,innerTbl.client_name AS name
FROM @lim_Live_Inbound AS innerTbl
WHERE innerTbl.lim_msg_id=GrpMsg.MsgId
FOR XML PATH('OrgnlGrpInfAndSts'),TYPE
)
FROM GrpMsg
FOR XML PATH('FIToFIPmtStsRp'),ROOT('Document')
结果
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:001.002.001.04">
<FIToFIPmtStsRp>
<GrpHdr>

我不知道您的数据来自哪里,但是 - 绝对硬编码 - 这就是方法:
WITH XMLNAMESPACES(DEFAULT 'urn:iso:std:iso:20022:tech:xsd:001.002.001.04')
SELECT 0 AS [GrpHdr/MsgId]
,0 AS [OrgnlGrpInfAndSts/OrgnlMsgId]
FOR XML PATH('FIToFIPmtStsRp'),ROOT('Document')
结果
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:001.002.001.04">
<FIToFIPmtStsRp>
<GrpHdr>
<MsgId>0</MsgId>
</GrpHdr>
<OrgnlGrpInfAndSts>
<OrgnlMsgId>0</OrgnlMsgId>
</OrgnlGrpInfAndSts>
</FIToFIPmtStsRp>
</Document>
