SQL OPENXML: Best Approach
Feb 27, 2008
Hello everyone.
I am new to.Net and here is what I have to do.
I needto update a SQL table with data coming from a XML file. I have seen some Microsoft documentation on this (the nice SQL statement that updates and inserts in the same stored procedure) but I don'tknow what is the best approach for passing my XML file to the stored procedure. The XML contains about 12 000 records, kind of phonebook info (name, email, phone).
What would be the best approach to do this? What objects should I use?
Thanks a million,
Ben

Hi
I've run into a problem using openxml and would greatly appreciate any help or direction!
The Xml document I am working with contains the following excerpt:
<Address>
<UKAddress>
<no>24</no>
<Line>A</Line>
<Line>B</Line>
<PostCode>GIR 0AA</PostCode>
</UKAddress>
</Address>
My problem is this: There can be a variable number of line elements (between 2 and 5), and in addition each element tag is identical to the others, i.e. Line.
I am trying to populate a SQL Server 2000 table (which contains the columns AddressLine1, AddressLine2, etc.) using OpenXML
Here's the code for my sproc....
.
...
.
EXEC sp_xml_preparedocument @idoc OUTPUT, @doc
SELECT *
FROM OPENXML (@idoc, 'root/data/', 2)
WITH (Number int '//no',
// address line detail here
Postcode varchar(10) '//PostCode')
.
...
.
I'm ok with OpenXML/sp_xml_preparedocument syntax and that, but I can't think how to handle unknown multiple address lines with the same tag name!
ANY HELP GREATLY RECEIVED!!!! :)

Hi,My application writes data into sql server.Currently it converts data into XML (an in memory XML string) and writeusing OPENXML.I want to know if i write it to a csv file and use BCP, then will it befaster then OPENXML. (i feel, writing to a csv will create IO operation thatwill slow down the process).Thanks

Hello, I am using OpenXML to do inserts/updates on Sql Server.
I have a problem with data type, for example, check this example:
DECLARE @record VARCHAR(1000)
SELECT @record = '<tests> <test> <NumberofChildren></NumberofChildren> <Name></Name> <Active></Active> </test></tests>' DECLARE @IndexInXML INT -- Create an internal representation of the XML document EXEC sp_xml_preparedocument @IndexInXML OUTPUT, @record INSERT INTO [test] SELECT [NumberofChildren], [Name], ISNULL([Active],null) FROM OPENXML (@IndexInXML, '/tests/test',2) WITH ( [NumberofChildren] INT, [Name] VARCHAR(50), [Active] BIT )
-- Remove in-memory table from memory EXEC sp_xml_removedocument @IndexInXML I have a table called test, it has the followig fields:1- ID2- NumberofChildren3- Name4- ActiveAll fields but ID are asisgned "Allow Null"I want to add data to this table, but if the value coming from xml is empty, I want to have null, in NumberofChildren, Name, Active.When I try my script, if the data is null, NumberofChildren with 0 value, Name is nothing, Active is 0,How can I make the INT and BIT datatypes have NULL when the input is empty in the xml?

I have an text column in a table that was intended to store XML data about queries that users submitted in our database. The problem appears that the application inserting records into the table doesn't do a great job of formatting the XML and I am having a great deal of trouble getting workable results.
The XML data in the table looks like:
<request>
<name>LastName</name>
<oper>=</oper>
<value>Smith</value>
<name>FirstName</name>
<oper>=</oper>
<value>John</value>
<name>MiddleName</name>
<oper>=</oper>
<value>Q.</value>
</request>
Note the groups of three elements (name, oper, value). These always appear sequentially in the data and there are always a fixed number of elements. If an element has no data, then it contains the value 'null' (ie, <value>null</value>).
I want to get a result like:
Col1 Col2 Col3
======== ====== ========
LastName = Smith
FirstName = John
MiddleName = Q
When I execute OPENXML, I specify option 2 (element centric) and the following WITH clause:
WITH (name varchar(10),
oper varchar(10),
value varchar(50) )
I get a single row returned. I have also tried:
WITH (name varchar(10) '@name',
oper varchar(10) '@oper',
value varchar(50) '@value')
I get a single row returned (with null values).
I've tried lots of other permutations, but nothing so far has worked. The only thing that has been modestly successful is to create and Edge Table (exclude the WITH clause), but that's really hard for me to work with. Another option is to insert a <line num="#">...<line> around each group of three elements (name, oper, value). That worked well, but it's a pain to implement (it means going back and updating all rows where the XML data exists and inserting the proper data.
I am by no means an XML guru, so if anyone has a suggestion, I'd love to hear it.
Regards,
hmscott

Hi everybody.
I don't know if anyone can help me but I have two issues with SQL Server 2000 SP4 (version 8.00.2039 - Desktop Engine) running on W2K and W2K3. I'm also running SQLXML 3.0 (msxml2.dll version is 8.30.9530.0).
Is it me or is sp_xml_preparedocument a crippled fat dog that is blind?...not that I have anything against crippled fat dogs that are blind :)
In all the stored procs I have developed, I pass a text var as an input parameter and return an IStream to ADO (using an sqlxml provider) in COM+. All has been very well and fine...until the passed text parameter resembles a data object of any decent size.
The first error I was noticing was a "XML Parsing Error: not enough storage is available to complete this operation". Well, I thought I would debug logically in a step fashion and just prepare the doc first and then do a return and then do a return on the next segment of code to find out where the issue is. I was amazed to find that sp_xml_preparedocument is taking 7 seconds to load a simple 1MByte text input var and around three minutes to load a 7 MByte file.
I believe these long load times are causing issues with transaction timouts etc so I thought I would try to solve the speed issue with sp_xml_preparedocument and then see if the "XML Parsing Error" continues.
So, my first question is:
Should sp_xml_preparedocument take 7 seconds to load a 1MByte text variable and nearly three odd minutes to load a 7 MByte file? Surely there is something wrong somewhere?
I'm also running these tests on two machines - one is 2 GHz and the other is 2.4 GHz P4's.
Cheers and thanks for any info.

Hi All,
I have an variable size XML file currently +/- 5 MB(8000+ records) but may be bigger. I need to INSERT/UPDATE each row. Which is the better way of doing this? Using selectNodes on the XML and INSERT/UPDATE each row via a SP or using sp_xml_preparedocument and OPENXML therefore only calling the SP once?

I've got thousands of XML docs and have to import those to the DB. AndI am having problem with getting some values because of tricky XMLformat.I didn't create this XML format and I don't like this format, OOP snobdid. And I(DBA) have to look after their mess.I've got XML doc like this :<customer><customer_id>12345</customer_id><first_name>Jason</first_name><last_name>Varitek</last_name><location><city>Boston</city><state>MA</state></location></customer>First, I did following :DECLARE @idoc intDECLARE @doc varchar(1000)SET @doc ='<customer><customer_id>12345</customer_id><first_name>Jason</first_name><last_name>Varitek</last_name><location><city>Boston</city><state>MA</state></location></customer>'EXEC sp_xml_preparedocument @idoc OUTPUT, @docSELECT *FROM OPENXML (@idoc, '/customer',2)WITH (customer_id int,first_name varchar(50),last_name varchar(50),location varchar(50))Then returned this which is not bad.customer_id | first_name |last_name |location12345 | Jason | Varitek |Boston MABut I need to return city and state in separated columns(I wish OOPsnobs made these as attributes in location element, instead ofelements).

I am researching the use of OpenXml for doing mass updates/inserts.Does anyone know how this procedure works as far as sql injection isconcerned? I've always been taught to use sp's with parameters...doesusing OpenXML open up any holes in that idea?My thinking is that it would be fine (maybe even better), because thefields will still be treated as literals.Alternatively, are there any other suggestions for doing massiveamounts of updates/inserts?

I am viewing a list of the reserved keywords for CE 3.5 and OPENXML is listed. Can you please tell me how I would implement this in CE 3.5? Since only one SQL statement can be sent with a SqlCeCommand then how can you prepare the document, access the xml data with OPENXML, and then close the document handle all in one call? For example, I have the following TSQL code in a SQL Express stored procedure and need to port it over to CE 3.5. Could you please help with some great ideas on how to go about this porting task?

Hi!
I am trying to import an xml file into a SQL 2005 table using sp_xml_prepareDocument ...OPENXML.
I always get 0 rows affected even though there is data in the file. The table structure is identical to the XML output. The OpenXML qry uses the following syntax:
FROM OPENXML(@xmlHndAdd, '/NewDataSet/Table1', 1)
WITH MyTbl
The XML file format is:
<NewDataSet xmlns="">
<Table1 diffgr:id="Table11" msdata:rowOrder="0">
<program_id>1-2-3-4-5</program_id>
<object_name />
</Table1>
<Table1 diffgr:id="Table12" msdata:rowOrder="1">
<object_id>6-7-8-9-0</object_id>
<object_name>ABC</object_name>
<objectproperty_id>1-3-5-7-9</objectproperty_id>
</Table1>
Any suggestions are greatly appreciated!!!

Hi
I've been banging my head against this one for a while. There are examples around but I can't seem to find anything that works (or find an explanation).
The problem: The xml document uses an imported common schema to reference common tags/objects (xmlns:cmn) but I can't seem to get openXML working with multiple namespaces. If I remove the primary namespace (emboldened in red) the SELECT returns as expected. Editing the xml document is not an option.
Here's (a simplified version) of my code...
--------------------------------------------------------------------
DECLARE @idoc INT
DECLARE @doc varchar (8000)
SET @doc ='
<?xml version="1.0" encoding="UTF-8"?>
<LHA_DATA xmlns="http://www.trs.co.uk/schema/DataShare.xsd" xmlns:cmn="http://www.trs.co.uk/schema/Common_ed.xsd">
<Manifest>
<cmn:senderRecipient>
<cmn:LACode>A0000</cmn:LACode>
<cmn:OfficeCode>0</cmn:OfficeCode>
</cmn:senderRecipient>
</Manifest>
</LHA_DATA>
'
EXEC sp_xml_preparedocument @idoc OUTPUT, @doc, '<LHA_DATA xmlns:cmn="xmlns="http://www.trs.co.uk/schema/DataShare.xsd" http://www.trs.co.uk/schema/Common_ed.xsd" />'
SELECT *
FROM OPENXML (@idoc, 'LHA_DATA', 2)
WITH (LACode varchar(10) '//cmn:LACode',
OfficeCode varchar(10) '//cmn:OfficeCode')
EXEC sp_xml_removedocument @idoc
------------------------------------------------------------------------

hi all,
I'm trying to get some xml data into sql server but i ran into this problem: openxml seems to repeat results ...
I simplified my example to this:
------------------------------------------------------
Declare @rDoc int,
@sDoc varchar(4000)
Set @sDoc = '
<ROOT>
<Rider>aaa</Rider>
<Rider>bbb</Rider>
<Rider>ccc</Rider>
</ROOT>'
EXEC sp_xml_preparedocument @rDoc OUTPUT, @sDoc
SELECT *
FROM OPENXML (@rDoc, 'ROOT/Rider', 1)
WITH (RiderName varchar(50) '../Rider')
----------------------------------------------------------
it returns 3 records for the 'rider' elements, _but_ all the records contain the text 'aaa' :/
does anybody know the solution to this?
cheers,
alex

Hi All,
The code (http://sqlxml.org/faqs.aspx?faq=100) below mirrors mine but is simplfied:
declare @i int
exec sp_xml_preparedocument @i output,
'<mydata>
<test xmlID="3" xmlData="blah blah blah"/>
<test xmlID="1" xmlData="blah"/>
</mydata>'
insert into test
select xmlID, xmlData
from OpenXml(@i, 'mydata/test')
with (xmlID int, xmlData nvarchar(30))
where xmlID not in (select xmlID from test)
update test
set test.xmlData = ox.xmlData
from OpenXml(@i, 'mydata/test')
with (xmlID int, xmlData nvarchar(30)) ox
where test.xmlID = ox.xmlID
exec sp_xml_removedocument @i
My question is when running this stored procedure for the first time, isn't one inserting AND then updating each row?

<BookName>SQLTeam Rocks</BookName>
</Book>
<Book>
<ForeignID>981</ForeignID>
<BookName>My SQL must get better</BookName>
</Book>
</Objects>
When I insert run the query I want to get the @@IDENTITY for each row and insert them with the corresponding ForeignID into a lookup table structured:
[ID Auto], [BooksID (from Books table)], [ForeignID (from XML)]
Any thoughts appreciated!

I am new to XML file to SQL table update. I use sp_xml_preparedocument and openxml to extract the fields from xml file but it returns NULL highlight below. I also notice both sp_xml_preparedocument and sp_xml_removedocument store procedures are not in SQL system store procedure.Â

I am learning how to parse XML data into SQL table. Below partial XML data contains multiple sections. I used OPENXML to parse one section but need to parse the remaining sections into a table. For example, below openxml code can only retrieve elements under "NewHires/Newhire/EmployeeInfo/PersonName" section. I also need to parse elements under "NewHires/Newhire/EmployeeInfo/ContactMethod" sections. Notice that there are three subsections underneath the ContactMethod section ("/Telephone", "/InternatEmailAddress", and "/PostalAddress") sections. Not to mention there are EmergencyContact section follow behind.Â
OpenXML can only extract one section at a time. Does it mean I have to write multiple OpenXML, store them into multiple temp tables then merge them into a single table? If that is the case, how to save all these data into a single table?Â
parse all the elements in lieu of OpenXML?
Here is the partial XML data:
<?xml version="1.0" encoding="UTF-8"?>

Hi all,I have a SQL job where I do the following -I check for new rows in my Table "DumpResults", every now and then and get the new rows to be inserted into table "CleanTable". I use OPENXML() to get the new data to be inserted but for some reason I don't get the right data through OPENXML() - DECLARE @intDoc INTDECLARE @xmlDoc VARCHAR(8000)IF(SELECT COUNT(*) FROM DumpResults WHERE DumpResults.C1 NOT IN (SELECT CleanTable.C1 FROM CleanTable)) > 0BEGINSET @xmlDoc = (SELECT * FROM DumpResults WHERE DumpResults.C1 NOT IN (SELECT CleanTable.C1 FROM CleanTable) FOR XML RAW) SET @xmlDoc = '<TABLE>' + @xmlDoc + '</TABLE>'
PRINT @xmlDocEXEC sp_xml_preparedocument @intDoc OUTPUT, @xmlDoc--INSERT INTO CleanTable(C1, C2, C3, C4, C5)
SELECT C1, C2, C3, C4, C5, C6 FROM OPENXML(@intDoc,'/row',1)WITH (C1 INT, C2 CHAR(3), C3 CHAR(3) , C4 FLOAT, C5 INT)EXEC sp_xml_removedocument @intDoc
END
ELSE Output that I get is - <TABLE><row C1="1" C2="AAA" C3="BBB" C4="1.000000000000000e+000" C5="2"/></TABLE>(0 row(s) affected) SO "PRINT @xmlDoc" is returning back the xml data (new results) it collected from the "DumpResults" table which isn't there in "CleanTable" but the "Select... FROM OPENXML(...)" doesn't return any result. why so? If anyone knows please reply If anyone has any better method to do it, inputs are welcome. Thanks

I seem to be getting very annoying behaviour from SQL Server and was wondering what the correct method should be...I want to store some binary data in the database and I want to use a stored procedure. I also want to pass some XML to the stored procedure where this XML contains the binary data. I will then use OPENXML to grab the binary data and stick in the table. In order to ensure the safe transmission of the binary through XML I Base64 encode it. Ok so far. The problem is that although OPENXML is supposed to assume that anything marked as Image/Binary will be Base64 encoded it then proceeds to Base64 encode it again and put that result into the database! So what am I missing, am I supposed use a CDATA section or something rather than Base64 encode my XML?

Hi,
I have some c# code which calls a SP which is erroring Basically I pass in a XML string which can be upto 5 MB is size (not sure about overflow issues here), which then calls a SP which inserts the data into a SQL table.
The c# code is as follows:
-------C#----------------------
SqlConnection conn = new SqlConnection(DBConn);
using(StreamReader sr = new StreamReader(xmlLocationString))
{
try
{
string @xmlInput = sr.ReadToEnd();
SqlCommand cmd = new SqlCommand();
cmd.Connection=conn;
cmd.CommandText = "[AddArgentinaTrades]";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new System.Data.SqlClient.SqlParameter("@xmlInput", SqlDbType.Text, 5120000));
cmd.Parameters["@xmlInput"].Direction = ParameterDirection.Output;
conn.Open();
cmd.ExecuteNonQuery();
}
catch(SqlException SqlExp)
{
Console.WriteLine(SqlExp.Message);
}
finally
{
conn.Close();
sr.Close();
}
}
------------------Stored Proc-----------------------
IF EXISTS (SELECT name FROM sysobjects WHERE name = 'AddArgentinaTrades' AND Type ='P')DROP PROCEDURE AddArgentinaTradesGO
CREATE PROCEDURE AddArgentinaTrades@xmlInput as textAS
Declare @idoc int
EXEC master.dbo.sp_xml_preparedocument @idoc OUTPUT, @xmlInput
INSERT INTO MarketRiskdev.dbo.Import_ArgentinaSELECT un_cid, tnum, snum, cid, entityid, ctype, why, comp, oc, bs, ae, cp, trd_date, set_date, mat_date, val_date, trader, famt, price, coupon, next_coupon, last_coupon, cpnfreq, cpnrate, cpntype, daycounttype, exch_notion,contract_spot, base_cur, year_basis, buy_currency, buy_amount, sell_currency, sell_amount, [timestamp] FROM OPENXML(@idoc, 'ArgentinaInputFile/Data',2)WITH (un_cid varchar(50), tnum nvarchar(50), snum nvarchar(50), cid varchar(50), entityid varchar(50), ctype varchar(50), why varchar(50), comp varchar(50), oc varchar(50), bs varchar(50), ae varchar(50), cp varchar(50), trd_date datetime, set_date datetime, mat_date datetime, val_date datetime, trader varchar(50), famt float(8), price float(8), coupon float(8), next_coupon datetime, last_coupon datetime, cpnfreq int, cpnrate float, cpntype int, daycounttype smallint, exch_notion smallint, contract_spot float(8), base_cur varchar(50), year_basis int, buy_currency varchar(50), buy_currency varchar(50), buy_amount float(8), sell_currency varchar(50), sell_amount float(8), [timestamp] varchar(50))
EXEC master.dbo.sp_xml_removedocument @idoc
GO
Error Msg:
A severe error occurred on the current command. The results, if any, should bediscarded.
Can anyone help here as I have no idea. I have tried reducing the size of XML to 5KB and still get the same error????
