在url中有xml文件：
<response> <sum>0</sum> <result>0</result> <comment>sel*1.9488|buy*1.9453</comment> </response>
现在想要存储过程,我可以从url解析这个xml文件,并更新为< comment>中的列值.ll * 1.9488 | buy * 1.9453< / comment>想添加购买* 1.9453到我的桌子.怎么样？
解决方法
要从URL获取XML,您需要执行以下操作：
sp_configure 'show advanced options',1; GO RECONFIGURE; GO sp_configure 'Ole Automation Procedures',1; GO RECONFIGURE; GO
然后,为了从URL获取XML(基于here的更新版本回答),下面创建一个临时表来存储该值,以便您可以使用xpath和子字符串处理结果.
这是一个使用google maps xml的工作示例,您需要更新url和xpath以满足您的特定要求.
USE tempdb
GO
IF OBJECT_ID('tempdb..#xml') IS NOT NULL DROP TABLE #xml
CREATE TABLE #xml ( yourXML XML )
GO
DECLARE @URL VARCHAR(8000)
DECLARE @QS varchar(50)
-- & or ? depending if there are other query strings
-- Use this for when there is other query strings:
SELECT @QS = '&date='+convert(varchar(25),getdate(),126)
-- Use this for when there is NO other query strings:
-- SELECT @QS = '?date='+convert(varchar(25),126)
SELECT @URL = 'http://maps.google.com/maps/api/geocode/xml?latlng=10.247087,-65.598409&sensor=false' + @QS
DECLARE @Response varchar(8000)
DECLARE @XML xml
DECLARE @Obj int
DECLARE @Result int
DECLARE @HTTPStatus int
DECLARE @ErrorMsg varchar(MAX)
EXEC @Result = sp_OACreate 'MSXML2.XMLHttp',@Obj OUT
EXEC @Result = sp_OAMethod @Obj,'open',NULL,'GET',@URL,false
EXEC @Result = sp_OAMethod @Obj,'setRequestHeader','Content-Type','application/x-www-form-urlencoded'
EXEC @Result = sp_OAMethod @Obj,send,''
EXEC @Result = sp_OAGetProperty @Obj,'status',@HTTPStatus OUT
INSERT #xml ( yourXML )
EXEC @Result = sp_OAGetProperty @Obj,'responseXML.xml'--,@Response OUT
SELECT yourXML.value('(//GeocodeResponse/status)[1]','VARCHAR(MAX)') from #xml
为了插入子字符串,您需要执行类似这样的操作以返回管道后的所有内容并添加到表中：
INSERT tableDestination (valueDestination)
SELECT substring(yourXML.value('(//response/comment)[1]','VARCHAR(MAX)'),charindex('|',yourXML.value('(//response/comment)[1]',1)+1,len(yourXML.value('(//response/comment)','VARCHAR(MAX)'))) from #xml
