XML Data from Relational Tables

Hi,
My requirement is to pull data from relational tables into xml format and port it to the user (either as a file or allow the user to access it directly from their browser). What is the best way to accomplish this. Your suggestions are appreciated.
thanks.

Marco,
Thanks for your reply, did try that , but I want the users to query this view also. Due to the nature of the xml structure I am getting the correct results. May be my xpath query is not right? My xml is as below:
<node1 attribute-node1 = "somevalue1">
<cnode1 attribute-cnode1 = "somevalue2">
<cnode2 attribute-cnode2 = "somevalue3">
<cnode3>somevalue4</cnode3>
<cnode4>somevalue5</cnode4>
</cnode2>
<cnode2 attribute-cnode2 = "somevlaue6">
<cnode3>somevalue6</cnode3>
<cnode4>somevalue7</cnode4>
</cnode2>
</cnode1>
</node1>
and my requirement is like : the user wants to see only cnode2 with attribute value "somevalue3" (along with the rest of the xml) ie
<node1 attribute-node1 = "somevalue1">
<cnode1 attribute-cnode1 = "somevalue2">
<cnode2 attribute-cnode2 = "somevalue3">
<cnode3>somevalue4</cnode3>
<cnode4>somevalue5</cnode4>
</cnode2>
</cnode1>
</node1>
Need the correct xpath query for this.
Thanks

Mapping with xml-schema XML-data to relational tables

Hello,
is it possible to map data from xml documents to relational tables with xml-schema?
I mean not in nested tables but in relational tables with primary and foreign keys!
With SQL Server 2005 it is very easy, I dont believe that Oracle couldn't do this!
I searched but i cant find anything about that!
Thx
user445232

indeed, oracle does this for xml schema based xmltype data, however, these underlying tables are not accessable to the application. Maybe It should for next version, so folks who like to use relational model can use it without mapping it manually.
Actually, nested tables, are the same, their underlying tables (segments) are indeed relational tables, oracle manages them internally and not visiable to the application. You can find them in the user_segments, user_objects views though.

Extracting data from Relational tables in 11.1.2.1

I want to extract the following data sets from relational tables
1. Attribute and its associated base member
2. Smartlist value of an account
Does any one have a code to extract this kind of data? Even pointing to the correct table names will be helpful.
Thanks

The table layouts can be found in the [documentation for EPMA|http://www.oracle.com/technetwork/middleware/bi-foundation/epm-data-models-11121-354684.zip] . If this doesn't work, there are other options to export hierarchies to text files. You can use life cycle management or the [EPMA File Generator|http://docs.oracle.com/cd/E17236_01/epm.1112/epma_file_gen_user/launch.html].

Create a large XML extract from relational tables - 10g

The Oracle 10g documentation recommends using the various SQL functions such as XMLAGG,XMLELEMENT or DBMS_XMLGEN under chapter "16 Generating XML Data from the Database" for generating a XML extract file. The DBMS_XMLDOM seems like a useful structured package to create a XML formatted extract. Any idea why Oracle does not recommend the use of XMLDOM API ? Are there performance issues or likely de-support ?
Whats the best way to produce a large XML extract?
Thanks.

mdrake wrote:
No reason not to use it. It just tends to require a lot more coding than the other methods. Underneath the covers they all map into the same code-line. In general, to generate a given XML document you wlll write far fewer lines of code using the SQL/XML operators. Less Code written = less code to maintan = faster time to market.Less code to parse...?

How to create xml file from relational tables in 10gR2

Hi,
I am very new to XML and was wondering how to create an XML file from querying relational tables. Some child tables may contain multiple rows that need to be returned in certain instances. Other queries will just be single or multiple rows from one or more tables. I would like to use the latest feathers in 10gR2. Thanks for any help you can provide.
Thanks,

Loading XML Data into Relational Table

Hello,
I receive an XML file generated from another tool (on Windows), I am trying to create a Linux shell script that will gather the needed XML file from my Linux database server, then have Oracle use this file to load the XML data into a relational table. This activity & data will be needed on an ongoing basis.
I have tried this two ways. First, I loaded the XML document into the database and tried to extract the data directly from the document, but that is not working. Now I want to try to read the data directly from the file on the server via select, however I am not getting any data returned. In the Select statement below, I am simply trying to query the data to see what is returned for my testing.
Create Table ci_results_table (transactionID Varchar2(100), //transactionID should be PrimaryKey but was getting NULL value errors during insert test, so removed PK
message Varchar2(200),
ci Varchar2(50),
processeddate xmltype,
status Varchar2(50),
sourcefile VarChar2(100));
select x.*
from XMLTable(
     'TSPLoadResults/Results'
     PASSING xmltype(bfilename('CMDB_DEVADHOCRESULTS_DIR','LoadResults-HP_146.results.xml'), nls_charset_id('AL32UTF8'))
     COLUMNS
       transactionID Varchar2(100) PATH 'TransactionID',
       Result XMLType PATH 'Result',
       Message Varchar2(200) PATH 'Message',
       PrimaryKey Varchar2(50) PATH 'PrimaryKey',
       ProcessedDate date PATH 'ProcessedDate',
       Status Varchar2(50) PATH 'Status',
       SourceFile VarChar2(100) PATH 'SourceFileName'
   ) x
Eventually I will need to build on this to limit the data returned to those records where SourceFileName is like 'HPDS%' and insert what is returned in to the ci_results_table. Attached is a sample Results XML file I am trying to load, It is named "ResultsTransformedtoUnix" because I used dos2Unix to convert it to Unix which may be right or wrong. (The output file I send out has to be transformed to DOS format before the other application can read it). Original file (before Unix conversion) named in script is also attached.
Please help. Thank you!

Hi,
I see some wrong things in your query.
1) The obvious one, explaining why you're not getting any data : there's a typo in the XQuery expression, it's "Result" not "Results"
2) ProcessedDate cannot be extracted as a date (at least not directly) since it actually represents a timestamp, use TIMESTAMP WITH TIME ZONE datatype and cast back to DATE in the SELECT clause
3) transactionID is an attribute, it must be accessed with '@' (or 'attribute::' axis)
4) If the file encoding is truly ISO-8859-1 as the prolog suggests, then do not use AL32UTF8 but the corresponding charset name : WE8ISO8859P1
Here's the working query :
select x.transactionID
     , x.Message
     , x.Primarykey
     , cast(x.ProcessedDate as date) ProcessDate
     , x.Status
     , x.SourceFile
from XMLTable(
       '/TSPLoadResults/Result'
       PASSING xmltype(bfilename('XML_DIR','LoadResults-HP_146.results.xml'), nls_charset_id('WE8ISO8859P1'))
       COLUMNS
         transactionID Varchar2(100)            PATH '@transactionID',
         Message       Varchar2(200)            PATH 'Message',
         PrimaryKey    Varchar2(50)             PATH 'PrimaryKey',
         ProcessedDate timestamp with time zone PATH 'ProcessedDate',
         Status        Varchar2(50)             PATH 'Status',
         SourceFile    VarChar2(100)            PATH 'SourceFileName'
     ) x
Using this query directly over the file will only perform decently (for large files) on 11.2.0.4 and onwards.
On prior versions, first load the file in a (temporary) XMLType column with Binary XML storage and SELECT from there.
because I used dos2Unix to convert it to Unix which may be right or wrong.
This conversion shouldn't be necessary.

Is there any way to improve Query which searches XML data from a table??

hi all,
i have a table which have one column say 'colA' as Varchar(max) datatype which i save xml data and it have other cols too
Currently i am searching data inside this table using like operator
eg:
Select * from tablename where colA like ‘%<tagname>parameterstringvalue</tagname>%’
when i check with the Execution plan i could see it Takes 82% for clusterd index scan ( primarykey col
not ColA)
i added new non clusterd index for the same with include col as ColA and i found nonclusterd index scan
with same estimated I O cost and Extimated operator cost as clusterd index scan
My Question is :-
1. why didnt nonclusterd index seek come?
2. In What way i can improve perfomance for such situvation? i had seen couple of post suggesting to rewrite the Query as SELECT
* FROM myTable WHERE CONTAINS (myCol1, myCol2, "myString").
I Try creating Full text index and found cost increased compared to the original Query ?
3. As per my assumption the wild charecter ('%') in begining makes perfomance issue is there any option
or an alternative for such case?

hi...i can give a skeleton
--Table Structure------------
Table1:-
(colA - int(PK),
ColB - Varchar(max),
ColC-uniquieidentifier,
ColD-datetime,
ColE-Bit)
It have clusterd index for ColA
Table2:-
(ColA-int(fk)
colF-int(pk)
colG-varchar(max),
ColH-uniqueidentifier,
colI-int,
colJ-int
ColK-date)
-----------------Query Skeleton-------------------:
select Distinct
s.colA,
s.ColB,
S.colC,
S.colD
from Table1 s with (nolock)
left outer join table2 Q with (nolock) on s.colA=q.ColA
where Q.ColA is null
and s.colB like '%<tag>sometext</tag>%'
and s.colD >='1/1/2010'
and s.colD <='1/1/2014'
i hope this will help to understand it clearly.........

Load XML Data into relational Table

Hi All,
I have a requirement to load data in an XML file into columns in an oracle table. This has to be done on the command line from a unix box which connects to a remote oracle DB.
Can some one give me a step by step procedure to do this (preferably using sqlloader) or point me in the right direction.
thank you

Hi,
Read "Oracle XML DB Developer's guide", Chapters 2,3,4,5.
That will give you very good idea.
The reason, I am suggesting reading is, there is not "one" way to do it. There can be many good ways, depending on the size, complexity of the XML and also your intended use of that XML data.
Regards

How could we read the XML data from a table using BODS.

Hi Guys,
My requirement is , As the OLTP system consists of a table called person which consists of a column demographics. so how could i read this XML data which is in one column of an SQL table called persons. As this XML data will populate the remaining fields in my target using BODS.
Regards,
Amjad.

Hi Amjad,
I am afraid there ain't any direct method to extract XML field from a data base.
Indirect way could be converting the whole table (instead of one field) into XML format and then extract one field from it!!

Hello michaels , thank you for the solution, still i am having some problems
Here is what i have done :
1.
SQL> CREATE DIRECTORY my_table_dir AS 'E:\table_files'
2 ;
Directory created.
2.
SQL> select * from myemp;
ENAME
SMITH
ALLEN
3.
This is the content of the existing xml file saved in the directory E:\table_files as emp.xml
<EMPLOYEES>
<EMP>JIM</EMP>
<EMP>RICK</EMP>
</EMPLOYEES>
4.
Now i executed this code :
declare
emp_xml xmltype;
begin
select sys_xmlagg (column_value, sys.xmlformat ('EMPLOYEES')) emp_xml
into emp_xml
from table (xmlsequence (cursor (select *
from myemp
where ename in ('SMITH', 'ALLEN')),
sys.xmlformat ('EMP')
dbms_xslprocessor.clob2file (emp_xml.getclobval (), 'E:\table_files', 'emp.xml');
end;
And the Error i got is :
