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

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.

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

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.

XML file validation with XSD and loading to database relational table

Hi all,
I have some xml files coming to my unix directory. I will be having an XSD for those. My task is to validate those xml against given xsd and load the corresponding data into oracle relational tables with sqlloader only.
Please help me to accomplish. and let me know the contents of control file ( for SQLLOADER) if i want to load the xml directly to database.
Unix and/or PLSQL suggestions both are welcome.

My problem area is loading the XML to Oracle relational tables using sqlloader.

RuleAuthor : error importing XML Schemas into Data Model

Hi,
I have problems during import XML Schema in my Data Model.
I'm following these steps:
1) Click Definitions tab;
2) Click XMLFact;
3) Click Create
4) I enter the path for the schema and the directory to store JAXB-generated classes. In this directory every user has all permission (777).
In the next step when I click on "Add Shemas" I have this error:

Do you still have enough disk space available on your file system to store the different xml-facts the RuleAuthor will create for you?

XML Schemas & XML SCHEMA COLLECTIONS: XSD.exe & the tool in C:\Program Files (x86)\Microsoft SDKs\Windows\v7..0A\Bin\x64?.

Hi all,
I just read Pages 346-348 of the book "Microsoft SQL Server 2012 Bible" written by A. Jorgensen, P. LeBlanc, J. Chinchilla, J. Segarra & A. Nelson (published by Wiley) regarding XML Schemas and XML SCHEMA COLLECTIONS: Step 1. create and
save orderxml.xml
<Order OrderID="1">
<Item>
<ItemNumber>V001</ItemNumber>
<Quantity>1</Quantity>
<Price>299.99</Price>
</Item>
</Order>
Step 2. using the tool in the following location:
C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\x64
Open a command prompt, and navigate the preceding directory. The syntax for creating schema is: Xsd.exe C:\temp\orderxml.xml /outputdirectory:c:\temp to create the orderxml.xsd file.
Step 3. Copy all the contents of the orderxml.xsd file to the clipboard, and create a new query window in SQL Server Management Studio, pasting in the content of the clipboard. To create the XML Schema Collection, you need to add the CREATE XML SCHEMA COLLECTION
statement to the beginning of the schema as shown below:
--MSss2012bibleP348.sql for XML Schema Collection OrderInformationSchemaCollection

I prepared (i) the orderxml.xml file for Step 1 and Step 2, and (ii) the MSss2012bibleP348.sql file for Step 3. But I am not sure that I can do the Steps (i) and (ii) in my PC that does not have the regular version of Microsoft SQL Server 2012 and Microsoft
Visual Studio 2012. Furthermore, I have difficulties to do Step 2 and Step 3 in my PC that is the part of Windows 7 Lan Computer System in my office: I navigated to my C:\Program Files (x86)\Microsoft SDKs\v7.0A\Bin\, I did not see the x64
thing in the Bin folder, but, I saw the xsd.exe in the Bin folder. If I click the xsd.exe and I get the following in the bottom of the PC screen:
xsd.exe Date modified:12/122011 12:55 PM    Date created: 12/12/2011 12:55 PM
Applicaion    Size:81.8 KB
Also, I see my PC screen flashes (and it looks like a dialog box with black background to flash for me to type the command) quickly. I am lost completely in this step and I don't understand the whole thing in doing Step 1, Step 2, and Step 3
I briefly summarized/described/presented above.
I need the following help from the experts of XML Schemas and XML Schema Collections in Microsoft SQL Server 2012 Management Studio:
Help #1: I don't understan the concept of Step 1, Step2 and Step 3 to do XML Schema, XSD.exe, and XML Schema Collection in the SQL Server 2012!!?? I just have the SQL Server 2012 Management Studio (SSMS2012) in my PC.
Help #2: How can I execute the xsd.exe in my C:\Program Files  (x86)\Microsoft SDKs\Windows\v7.0A\Bin\ folder?
Help #3: I just learned the basic things of creating XML SCHEMA COLLECTIONS in my SSMS2012 directly. Is the MSss2012P348.sql (I created and presented above) right for the task? How can I use clipboard to create the XML Schema Collection in my ScottChangDB
database?
Please kindly help and give me the answers/comments for Help #1, Help #2 and Help #3.

Step1 and Step2 not that related to SQL Server, you can get the XSD from a given XML with an online XSD generator.

Create XML (using DTD) from multiple relation tables

Hello and thank you in advanced.
I'm trying to create an XML document, based on a specific DTD, by selecting information from multiple tables in the database.
Is there a tool (in XDK maybe?) that will allow me to map my relational tables to a specific DTD?
I could build the XML manually, but I was hoping that Oracle has already solved this problem with an automated tool.
Thanks again,
Sean Cloutier

Is that the same thing as me writing an XSQL document which contains all of my queries (or views).
In other words, do I have to map everything by hand or is there a tool to do that for me?
thanks again,

Help with writing and retrieving data from a table field with type "LCHR"

Hi Experts,
I need help with writing and reading data from a database table field which has a type of "LCHR". I have given an example of the original code but don't know what to change it to in order to fix it and still read in the original data that's stored in the LCHR field.
Basically we have two Function modules, one that saves list data to a database table and one that reads in this data. Both Function modules have an identicle table which has an array of fields from type INT4, CHAR, and type P. The INT4 field is the first one.
Incidentally this worked in the 4.7 non-unicode system but is now dumping in the new ECC6 Unicode system.
Thanks in advance,
C
SAVING THE LIST DATA TO DB
DATA: L_WA(800).

ZDBTAB-LINENUM = SY-TABIX.
INSERT ZDBTAB.

             SEQNR type ZDBTAB-LINENUM,

Select the data.
SELECT linenum rawdata from ZDBTAB into table T_DATA
     WHERE repid = w_repname
     AND rundate = w_rundate
     ORDER BY linenum.
Populate calling Internal Table.
LOOP AT T-DATA.
APPEND T_DATA to T_TAB.
ENDLOOP.

Hi Anuj,
The unicode flag is active.
When I run our report and then to try and save the list data a dump is happening at the following point
LOOP AT T_TAB into L_WA.
As I say, T_TAB consists of different fields and field types whereas L_WA is CHAR 800. The dump mentions UC_OBJECTS_NOT_CONVERTIBLE
When I try to load a saved list the dump is happening at the following point
APPEND T_DATA-RAWDATA to T_TAB.
T_DATA-RAWDATA is type LCHR and T_TAB consists of different fields and field types.
In both examples the dumps mention UC_OBJECTS_NOT_CONVERTIBLE

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].

Load XML Document/Data into relational Table

Hi All,
I have a requirement to load data in an XML file into an oracle db and subsequently split the contents 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 or point me in the right direction.
thank you

Hi,
There can be many different way we can achieve this. Mainly depending on size of XML, complexity of XML and your use of that data (e.g. you just want to insert XML into relational or you want to write something and the generate new xmls later on).
If you go to Oracle online documentation -> Oracle XML DB Developer's guide, first 3-4 chapters will give you what you need.

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.

InfoPath 2010 SQL Data Connection - Related Table is Not a Repeating Group

I'm creating a InfoPath 2010 database form. In my main connection I want to query a parent table and a related child table. When I go through the wizard, the resulting data structure is not correct. The child group that InfoPath creates isn't
a repeating group, but it should be. I've done this many times before and never had this problem.
In other words, when I open up the main data source, the little blue disclosure triangle is missing from the child group.
Any help would be greatly appreciated.
Thank you.

Hi,
ODBC driver for Excel does not support deleting data.
I'm afraid there is no solution via SQL as in Oracle to use SQL with Excel you can only use ODBC, see OLEDB in previous versions to 11G.
Unfortunately with ODBC or OLEDB driver for Excel , DELETE is not supported.

Query to obtain tables in SH schema using data-dictionary views/tables.

Hi,
I have just installed Oracle 10g Database. Logged on to SQL Plus by scott (changed the password as prompted).
I want to see the tables in SH schema (which comes by default with Oracle 10g database).
The problem, I am facing is:
I can see the schema name: SH in the result of the below query:
SELECT * FROM ALL_USERS
but, nothing is returned in the result of the below query:
SQL> SELECT OWNER FROM ALL_TABLES WHERE OWNER='SH';

Why is this happening?
What will be the correct query to obtain tables present in SH schema ?
Thanks in Advance & Regards,
