标签: sql-server xml

我在互联网上搜索过,并没有将xml文件转换为SQL Server表的好例子。

我有这个文件:

<http://www.ims.gov.il/ims/PublicXML/isr_cities.xml>

这是15个城市的天气文件(接下来的4天)。

如何将其加载到SQL Server中的平面表?

我尝试它只是给我null: - (

我提出了一些产生问题的价值,但我仍然无法将其转换为大型平台。

如何将xml文件中的所有节点都放出来?

谢谢!

您可以尝试这样的方法(假设您在名为@input XML的SQL Server变量中包含XML):

SELECT
    LocationId = XC2.value('(LocationId)[1]', 'int'),
    LocNameEng = XC2.value('(LocationNameEng)[1]', 'varchar(100)'),
    TheDate = XCE.value('(../Date)[1]', 'DATE'),
    ElementName = XCE.value('(ElementName)[1]', 'varchar(50)'),
    ElementValue = XCE.value('(ElementValue)[1]', 'varchar(50)')
FROM
    @input.nodes('/IsraelCitiesWeatherForecastEvening/Location') AS XT(XC)
CROSS APPLY
    XC.nodes('LocationMetaData') AS XT2(XC2)
CROSS APPLY
    XC.nodes('LocationData/TimeUnitData/Element') AS XTE(XCE)

这应该至少给你一些输出,并且可以作为更多探索的起点服务器!

我认为这可能就是你想要的。在通话结束后,您可以根据需要使用XML ...

--you need to allow this:
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ole Automation Procedures', 1;
GO
RECONFIGURE;
GO

DECLARE  @URL VARCHAR(MAX) = 'http://www.ims.gov.il/ims/PublicXML/isr_cities.xml';

DECLARE @xmlT TABLE (yourXML XML);
DECLARE @Response NVARCHAR(MAX);
DECLARE @XML XML;
DECLARE @Obj INT;
DECLARE @Result INT;
DECLARE @HTTPStatus INT;
DECLARE @ErrorMsg NVARCHAR(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', NULL, 'Content-Type', 'application/x-www-form-urlencoded';
EXEC @Result = sp_OAMethod @Obj, SEND, NULL, '';
EXEC @Result = sp_OAGetProperty @Obj, 'status', @HTTPStatus OUT ;

INSERT @xmlT ( yourXML )
EXEC @Result = sp_OAGetProperty @Obj, 'responseXML.xml';

SELECT * FROM @xmlT;

问题出在我当地的环境......

无论如何我的代码经过改进。我还在努力...... 谢谢你们所有人!

DECLARE @WeatherXML xml 
SET @WeatherXML = (  SELECT  *      FROM    
           OPENROWSET (BULK 'C:\Stam\isr_cities.xml', SINGLE_BLOB) AS FileImport (XMLDATA))
SELECT 
        wXML.query('../../../LocationMetaData/LocationId').value('.','NVARCHAR(30)'), 
        wXML.query('../../../LocationMetaData/LocationNameEng').value('.','NVARCHAR(30)'), 
        wXML.query('../../../LocationMetaData/LocationNameHeb').value('.','NVARCHAR(30)'), 
        wXML.query('../../../LocationMetaData/DisplayLat').value('.','NVARCHAR(30)'), 
        wXML.query('../../../LocationMetaData/DisplayLon').value('.','NVARCHAR(30)'),
        wXML.query('../Date').value('.','NVARCHAR(30)'), 
        wXML.query('ElementName').value('.','NVARCHAR(30)'), 
        wXML.query('ElementValue').value('.','NVARCHAR(30)')
FROM @WeatherXML.nodes('/IsraelCitiesWeatherForecastMorning/Location/LocationData/TimeUnitData/Element') AS XmlData(wXML)

我必须需要元素节点,但是为了开始,我做了类似的事情:

DECLARE @WeatherXML xml 
SET @WeatherXML = (  SELECT  *  FROM    
        OPENROWSET (BULK 'C:\Stam\isr_citiesNEW.xml', SINGLE_BLOB) AS FileImport (XMLDATA))

-- insert xml to [MOT_Temp_WeatherXML] table
INSERT INTO [dbo].[MOT_Temp_WeatherXML]
           ([LocationId]
           ,[LocationNameEng]
           ,[LocationNameHeb]
           ,[DisplayLat]
           ,[DisplayLon]
           )SELECT 
                    wXML.query('LocationId').value('.','NVARCHAR(30)'), 
                    wXML.query('LocationNameEng').value('.','NVARCHAR(30)'), 
                    wXML.query('LocationNameHeb').value('.','NVARCHAR(30)'), 
                    wXML.query('DisplayLat').value('.','NVARCHAR(30)'), 
                    wXML.query('DisplayLon').value('.','NVARCHAR(30)')
            FROM    @WeatherXML.nodes('/IsraelCitiesWeatherForecastMorning/Location/LocationMetaData') AS XmlData(wXML)

SELECT * FROM [MOT_Temp_WeatherXML]

之后我进入结果:

<LocationId>520</LocationId> 

等等......而不只是520 ......

但是,如果我得到元素节点,我会很高兴...
