嗨我需要sql中的以下帮助:
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>
目前我有一个保存主要信息的变量,我建立了信息之间(认为grphdr可以多次插入主xml,具有不同的信息)
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
然后当我将grphdr添加回主xml时
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
<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)来删除,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
必须生成这样的
<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.如果任何人能以更好的方式帮助我,我将不胜感激.
解决方法
编辑2:我终于找到了避免重复命名空间的方法.首先创建没有命名空间的嵌套XML,然后加入它:
更新(2017年12月)
实际上,这种解决方法仍然没有实际帮助.命名空间xmlns =“”被视为*内部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来删除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)仍然没有解决.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=""> <OrgnlMsgId>00012016-02-25000000023</OrgnlMsgId> <name>Mr Piet</name> </OrgnlGrpInfAndSts> <OrgnlGrpInfAndSts xmlns=""> <OrgnlMsgId>00012016-02-25000000022</OrgnlMsgId> <name>Mrs Name</name> </OrgnlGrpInfAndSts> </FIToFIPmtStsRp> </Document>
您将使用CAST(REPLACE(CAST(TheXMLHere AS NVARCHAR(MAX)),’xmlns =“”’,”)AS XML)来摆脱错误的空名称空间….
编辑:适合您的样本数据的新方法
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),'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],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> <MsgId>021/00210006/20160225/000002</MsgId> </GrpHdr> <OrgnlGrpInfAndSts xmlns="urn:iso:std:iso:20022:tech:xsd:001.002.001.04"> <OrgnlMsgId>00012016-02-25000000023</OrgnlMsgId> <name>Mr Piet</name> </OrgnlGrpInfAndSts> <OrgnlGrpInfAndSts xmlns="urn:iso:std:iso:20022:tech:xsd:001.002.001.04"> <OrgnlMsgId>00012016-02-25000000022</OrgnlMsgId> <name>Mrs Name</name> </OrgnlGrpInfAndSts> </FIToFIPmtStsRp> </Document>
这是第一种方法
我不知道你的数据来自哪里,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>
