Passing irregular xml file to the stored procedure - sql

Question

I have a sample xml as follows. I am trying to get all or specific data and then insert into the my sql table which has the same columns representing the values coming from xml. I looked through some solutions but the xml files are not formatted like I have in here. Can you help me?
<?xml version="1.0" encoding="UTF-8" standalone="true"?>
<VehicleStatusResponse xmlns:ns2=
"http://fms-standard.com/rfms/v1.0.0/xsd/common/position" xmlns="http://fms-standard.com/rfms/v1.0.0/xsd/status">
<VehicleStatus>
<VIN>VF254ANA735752628</VIN>
<TriggerType>TIMER</TriggerType>
<CreatedDateTime>2014-09-08T09:30:20</CreatedDateTime>
<ReceivedDateTime>2014-09-08T09:30:57</ReceivedDateTime>
<GNSSPosition>
<ns2:Latitude>49.18557</ns2:Latitude>
<ns2:Longitude>11.18557</ns2:Longitude>
<ns2:Heading>33</ns2:Heading>
<ns2:Altitude>500</ns2:Altitude>
<ns2:Speed>16.4</ns2:Speed>
<ns2:PositionDateTime>2014-09-08T09:30:20</ns2:PositionDateTime>
</GNSSPosition>
<WheelBasedSpeed>16.07</WheelBasedSpeed>

<HRTotalVehicleDistance>817.5</HRTotalVehicleDistance>
<EngineTotalFuelUsed>575</EngineTotalFuelUsed>
<FuelLevel1>83</FuelLevel1>
<CatalystFuelLevel>88.48</CatalystFuelLevel>
<GrossCombinationVehicleWeight>10000</GrossCombinationVehicleWeight>
</VehicleStatus>
</VehicleStatusResponse>

Answer 1

You can use an XML type and XML methods if you remove or modify the declaration. The SQL Server XML type only supports UCS-2 encoding and doesn't recognize "standalone". The example below uses string manipulation to tweak the declaration. You'll need to change the data types according to your actual column types and should specify an explicit column list on the INSERT statement. I omitted that in this example only because I didn't want to assume your actual table columns matched the element names in the XML.
DECLARE #xml xml;
DECLARE #xmlString nvarchar(MAX) = N'<?xml version="1.0" encoding="UTF-8" standalone="true"?>
<VehicleStatusResponse xmlns:ns2=
"http://fms-standard.com/rfms/v1.0.0/xsd/common/position" xmlns="http://fms-standard.com/rfms/v1.0.0/xsd/status">

</VehicleStatusResponse>';
SET #xmlString = REPLACE(#xmlString, 'encoding="UTF-8"', 'encoding="UCS-2"');
SET #xmlString = REPLACE(#xmlString, 'standalone="true"', '');
SET #xml = #xmlString;

First of all you need to get your value into a declare variable of type XML or into an XML-typed data table column. As your XML contains namespaces you have to declare them in a WITH XMLNAMESPACES first. You might use wildcard syntax (*:), but its better to be as specific as possible.
The .nodes() call navigates to the Level of <VehicleStatus>. All elements below are simply 1:1 and easy to read...
You can try it like this:
DECLARE #xml XML=
N'<VehicleStatusResponse xmlns:ns2=
"http://fms-standard.com/rfms/v1.0.0/xsd/common/position" xmlns="http://fms-standard.com/rfms/v1.0.0/xsd/status">
<VehicleStatus>
<VIN>VF254ANA735752628</VIN>
<TriggerType>TIMER</TriggerType>
<CreatedDateTime>2014-09-08T09:30:20</CreatedDateTime>
<ReceivedDateTime>2014-09-08T09:30:57</ReceivedDateTime>
<GNSSPosition>
<ns2:Latitude>49.18557</ns2:Latitude>
<ns2:Longitude>11.18557</ns2:Longitude>
<ns2:Heading>33</ns2:Heading>
<ns2:Altitude>500</ns2:Altitude>
<ns2:Speed>16.4</ns2:Speed>
<ns2:PositionDateTime>2014-09-08T09:30:20</ns2:PositionDateTime>
</GNSSPosition>
<WheelBasedSpeed>16.07</WheelBasedSpeed>
<TachographSpeed>15.83</TachographSpeed>
<HRTotalVehicleDistance>817.5</HRTotalVehicleDistance>
<EngineTotalFuelUsed>575</EngineTotalFuelUsed>
<FuelLevel1>83</FuelLevel1>
<CatalystFuelLevel>88.48</CatalystFuelLevel>
<GrossCombinationVehicleWeight>10000</GrossCombinationVehicleWeight>
</VehicleStatus>
</VehicleStatusResponse>';
--This is the query
WITH XMLNAMESPACES(DEFAULT 'http://fms-standard.com/rfms/v1.0.0/xsd/status'
,'http://fms-standard.com/rfms/v1.0.0/xsd/common/position' AS ns2)
SELECT vs.value('VIN[1]','nvarchar(max)') AS VehicleStatus_VIN
,vs.value('TriggerType[1]','nvarchar(max)') AS VehicleStatus_TriggerType
,vs.value('CreatedDateTime[1]','datetime') AS VehicleStatus_CreatedDateTime
,vs.value('ReceivedDateTime[1]','datetime') AS VehicleStatus_ReceivedDateTime
,vs.value('(GNSSPosition/ns2:Latitude)[1]','decimal(14,6)') AS VehicleStatus_GNSSPosition_Latitude
,vs.value('(GNSSPosition/ns2:Longitude)[1]','decimal(14,6)') AS VehicleStatus_GNSSPosition_Longitude
/*other columns follow the same pattern*/
FROM #xml.nodes('/VehicleStatusResponse/VehicleStatus') AS A(vs)
update: insert into a table
Easiest was to wrap this call as CTE like
WITH XMLNAMESPACES(...)
,DerivedTableCTE AS
(
The query here
)
INSERT INTO YourTable (col1, col2, col3, ...)
SELECT col1, col2, col3, ...
FROM DerivedTableCTE
