insert data from xml column into temp table - sql

Question

I have a xml column that look like
SET #XMLData = '<ArrayOfEntityNested xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.Bijak">
<EntityNested>
<Id xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto">1</Id>
<Date xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak">0001-01-01T00:00:00</Date>
<Description xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak">deesc</Description>
<Number xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak" i:nil="true" />
</EntityNested>
</ArrayOfEntityNested>'
I need insert data from the XML into a temp table.
here
For this I use from following code. But it's not working, and it's not inserting any data into temp table.
--Variables Decleration
DECLARE #XMLData VARCHAR(MAX)
DECLARE #idoc INT
-- Creating Temporary Table
CREATE TABLE #TEMP_TABLE
(
REC_ID INT IDENTITY(1,1),
[Id] INT,
[Date] VARCHAR(50),
[Number] VARCHAR(50),
);
--Case 1
SET #XMLData = '<ArrayOfEntityNested xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.Bijak">
<EntityNested>
<Id xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto">1</Id>
<Date xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak">0001-01-01T00:00:00</Date>
<Number xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak" i:nil="true" />
</EntityNested>
</ArrayOfEntityNested>
'
--Reading Data from XML and inserting into Temp Table
EXECUTE sp_xml_preparedocument #idoc OUTPUT, #XMLData
INSERT INTO #TEMP_TABLE
SELECT *
FROM OpenXML(#idoc,'/ArrayOfEntityNested/EntityNested', 1)
WITH #TEMP_TABLE
EXECUTE sp_xml_removedocument #idoc
--Displaying data from Temp Table
SELECT * FROM #TEMP_TABLE
DROP TABLE #TEMP_TABLE;
But that doesn't work, if xml format correct might look like :
SET #XMLData = '<ArrayOfEntityNested>
<EntityNested>
<Id>1</Id>
<Date>0001-01-01T00:00:00</Date>
<Description>deesc</Description>
<EmployeeId>2</EmployeeId>
<IsDeleted>false</IsDeleted>
<LoadingPermitTruckId>7541</LoadingPermitTruckId>
</EntityNested>
</ArrayOfEntityNested>'
then it works.
Please help me.

Answer 1

First of all - please use appropriate data types! If your source data is XML - why aren't you using the XML datatype?
Also, if you have a Date in your table - why isn't that a DATE or DATETIME type?? And why is the Number a VARCHAR(50) ??
Makes no sense......
Then: you're not looking at the XML namespaces that are present in the XML document - but you must!
At lastly - I would recommend using the native XQuery support instead of the legacy, deprecated sp_xml_preparedocument / OpenXML approach....
Seems much easier, much clearer to me...
Use this:
-- variable declaration
DECLARE #XMLData XML
-- creating temporary table
CREATE TABLE #TEMP_TABLE
(
REC_ID INT IDENTITY(1,1),
[Id] INT,
[Date] DATETIME2(3),
[Number] INT
);
and then use proper XQuery statements, including the XML namespaces to handle the data:
SET #XMLData = '<ArrayOfEntityNested xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.Bijak">
<EntityNested>
<Id xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto">1</Id>
<Date xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak">0001-01-01T00:00:00</Date>
<Number xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak" i:nil="true" />
</EntityNested>
<EntityNested>
<Id xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto">42</Id>
<Date xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak">2013-12-22T14:45:00</Date>
<Number xmlns="http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak">373</Number>
</EntityNested>
</ArrayOfEntityNested>'
;WITH XMLNAMESPACES ('http://schemas.datacontract.org/2004/07/Gbms.Dto.Bijak' AS ns1,
'http://schemas.datacontract.org/2004/07/Gbms.Dto' AS ns2,
'http://schemas.datacontract.org/2004/07/Gbms.Dto.VirginBijak' AS ns3)
INSERT INTO #TEMP_TABLE(ID, Date, Number)
SELECT
xc.value('(ns2:Id)[1]', 'int'),
xc.value('(ns3:Date)[1]', 'DateTime2'),
xc.value('(ns3:Number)[1]', 'int')
FROM
#XmlData.nodes('/ns1:ArrayOfEntityNested/ns1:EntityNested') AS xt(xc)

Answer 2

DECLARE #idoc int
DECLARE #doc varchar(1000)
SET #doc ='
<OutLookContact>
<Contact FirstName="Asif" LastName="Ghafoor" EmailAddress1="asifghafoor#my.web.pk" />
<Contact FirstName="Rameez" LastName="Ali" EmailAddress1="rameezali#my.web.pk" />
</OutLookContact>'
--Create an internal representation of the XML document.
EXEC sp_xml_preparedocument #idoc OUTPUT, #doc
-- Execute a SELECT statement that uses the OPENXML rowset provider.
DECLARE #Temp TABLE(FirstName VARCHAR(250),LastName VARCHAR(250),Email1 VARCHAR(250))
INSERT INTO #Temp(FirstName,LastName,Email1)
SELECT *
FROM OPENXML (#idoc, '/OutLookContact/Contact',1)
WITH (FirstName varchar(50),LastName varchar(50),EmailAddress1 varchar(50))
select FirstName,LastName,Email1 from #Temp

it will be a lot easier if you try to use a tool called pentaho. http://en.wikipedia.org/wiki/Pentaho
it is an open source tool which is used for data integration.you can create a database connection from mysql or oracle to it and do the transformation.it is easy to use.
