Hello everyone. I'm writing a proc that imports several XML files and stores them in a SQL table.
Here's a sample of the XML Data:
And my query is below. Notice that only the Elements are importing but the Attributes are NOT. The Attributes I need imported that are not working are BaseVehicle, Aspiration, PartType and Position but they are all coming in a nulls or zeroes. The QTY, MFrLable and Part fields are all coming in OK. I've tried numerous variants of the query and can't get it to work. Any Help would be Greatly Appreciated! Thank you.

Can you please post the XML rather than a picture of it!

Have you tried using 'nodes'?

md44 SSC Veteran Points: 260 More actions · Answer 4

Yes I have but I get the same result where all values with an attribute show up as zero or null.

If someone could please post a query on how I can retrieve all the attributes and elements in the XML file, it would be much appreciated. I took a stab at this using the nodes() method but still no luck. I'm sure I'm doing something wrong but again, any help here would be much appreciated.

Thanks

Here is an example XQuery to read both the values and the attributes.
😎

USE TEEST; GO SET NOCOUNT ON;

DECLARE @TXML XML = '<?xml version="1.0" encoding="iso-8859-1"?> <ACES version="3.0"> <App action="A" id="1"> <BaseVehicle id="61" /> <Qty>1</Qty> <PartType id="1684" /> <MfrLabel>Ferodo</MfrLabel> <Position id="22" /> <Part>FDB11</Part> </App> <App action="A" id="2"> <BaseVehicle id="65" /> <Aspiration id="6" /> <Qty>1</Qty> <PartType id="1684" /> <MfrLabel>Ferodo</MfrLabel> <Position id="22" /> <Part>FDB451</Part> </App> <App action="A" id="3"> <BaseVehicle id="65" /> <Aspiration id="6" /> <Qty>1</Qty> <PartType id="1684" /> <MfrLabel>Ferodo</MfrLabel> <Position id="30" /> <Part>FDB451</Part> </App> </ACES>';

SELECT APP.DATA.value('(BaseVehicle/@id)[1]' ,'INT' ) AS BaseVehicle ,APP.DATA.value('(Qty/text())[1]' ,'INT' ) AS Qty ,APP.DATA.value('(PartType/@id)[1]' ,'INT' ) AS PartType ,APP.DATA.value('(MfrLabel/text())[1]' ,'varchar(50)' ) AS MfrLabel ,APP.DATA.value('(Position/@id)[1]' ,'INT' ) AS Position ,APP.DATA.value('(Part/text())[1]' ,'varchar(50)' ) AS Part FROM @TXML.nodes('ACES/App') APP(DATA);

Sorry, one more small question. Some of the xml files I'll be importing are quite large and storing all the xml in a variable takes several minutes and consumes lots of resources. As part of a nightly job, I'd like to import all the xml into a staging table then use use your query but rather than read from a variable, I would be reading from a table... How would I modify your select statement to generate the same result but reading from a table that contains an XML data type rather than a xml variable?

How would I modify your select statement to generate the same result but reading from a table that contains an XML data type rather than a xml variable?

Here is an example, note that I'm just using a table variable, in your case that would be a normal table.

USE TEEST; GO SET NOCOUNT ON; -- https://www.sqlservercentral.com/Forums/2013480/Problem-reading-all-Attributes-into-SQL-table -- TABLE VARIABLE AND SAMPLE DATA; DECLARE @XML_TABLE TABLE ( XML_ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED ,XML_DATA XML NOT NULL );

DECLARE @TXML XML = '<?xml version="1.0" encoding="iso-8859-1"?> <ACES version="3.0"> <App action="A" id="1"> <BaseVehicle id="61" /> <Qty>1</Qty> <PartType id="1684" /> <MfrLabel>Ferodo</MfrLabel> <Position id="22" /> <Part>FDB11</Part> </App> <App action="A" id="2"> <BaseVehicle id="65" /> <Aspiration id="6" /> <Qty>1</Qty> <PartType id="1684" /> <MfrLabel>Ferodo</MfrLabel> <Position id="22" /> <Part>FDB451</Part> </App> <App action="A" id="3"> <BaseVehicle id="65" /> <Aspiration id="6" /> <Qty>1</Qty> <PartType id="1684" /> <MfrLabel>Ferodo</MfrLabel> <Position id="30" /> <Part>FDB451</Part> </App> </ACES>';

INSERT INTO @XML_TABLE(XML_DATA) SELECT @TXML UNION ALL SELECT @TXML UNION ALL SELECT @TXML UNION ALL SELECT @TXML ; -- TABLE SELECT SELECT TX.XML_ID ,APP.DATA.value('(BaseVehicle/@id)[1]' ,'INT' ) AS BaseVehicle ,APP.DATA.value('(Qty/text())[1]' ,'INT' ) AS Qty ,APP.DATA.value('(PartType/@id)[1]' ,'INT' ) AS PartType ,APP.DATA.value('(MfrLabel/text())[1]' ,'varchar(50)' ) AS MfrLabel ,APP.DATA.value('(Position/@id)[1]' ,'INT' ) AS Position ,APP.DATA.value('(Part/text())[1]' ,'varchar(50)' ) AS Part FROM @XML_TABLE TX CROSS APPLY TX.XML_DATA.nodes('ACES/App') APP(DATA);

You can also shred the XML into the table as you load it, sometimes this is better if the XML is very large.

DECLARE @XML_TABLE_ROWS TABLE ( XML_ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED ,XML_DATA XML NOT NULL );

INSERT INTO @XML_TABLE_ROWS(XML_DATA) SELECT APP.DATA.query('.') FROM @TXML.nodes('/ACES/App') APP(DATA);

The adjusted query
SELECT TXR.XML_ID ,APP.DATA.value('(BaseVehicle/@id)[1]' ,'INT' ) AS BaseVehicle ,APP.DATA.value('(Qty/text())[1]' ,'INT' ) AS Qty ,APP.DATA.value('(PartType/@id)[1]' ,'INT' ) AS PartType ,APP.DATA.value('(MfrLabel/text())[1]' ,'varchar(50)' ) AS MfrLabel ,APP.DATA.value('(Position/@id)[1]' ,'INT' ) AS Position ,APP.DATA.value('(Part/text())[1]' ,'varchar(50)' ) AS Part FROM @XML_TABLE_ROWS TXR CROSS APPLY TXR.XML_DATA.nodes('/App') APP(DATA);

None of those elements have an "id" attribute, which is why you are getting NULL values. Also, none of those contain integer data. Try the following instead.

SELECT Header.DATA.value('(Company/text())[1]' ,'varchar(50)' ) AS Company ,Header.DATA.value('(MfrCode/text())[1]' ,'VARCHAR(50)' ) AS MfrCode ,Header.DATA.value('(BrandAAIAID/text())[1]' ,'VARCHAR(50)' ) AS BrandAAIAID ,Header.DATA.value('(EffectiveDate/text())[1]' ,'Datetime' ) AS EffectiveDate FROM @TX.nodes('/ACES/Header') Header(DATA)
