XML using PL-SQL

Hi All,
I am trying to use XML for building an application. Is it
possible to generate page by only using a PL-SQL?
I know how to generate XML by using PL-SQL.
--How can I apply XSL document to it?
Thanks,
Samir

The XML Developers kit available on this site at: http://technet.oracle.com/tech/xml/
contains utilities for parsing XML with PL/SQL and other methods.

Generating XML using PL/SQL

hi All,
We have an interface across two different applications in an organisation. Data is ported across these two application in a flat file which has specific format. These files are generated using generic pro c programs. Now we are planning to replace these files with XML. Also to replace generic pro c with PL/SQL to generate and read XML files. Now my question is, whether using PL/SQL to generate/read XML file will be faster than generating/reading flat files using pro c? Will the performance improve significantly? If anybody has worked on this, your inputs will be valuable.
Thanks in advance. Hoping to hear something veru soon from the masters.

Rajesh

Generate connections.xml using only sql commands

Hello,
I have a database, where all connection information (Hostname, User, Port, SID, etc.) are stored for several databases. Now I want to create the connections.xml which I can import to the SQL Developer. The idea is to administer the connection information in a single point. Then anyone can query and import the connections easily to the SQL Developer.
The structure itself was easy to understand and implement using XMLELEMENT. My Problem is, how can I save the password respectively how is the password encrypted? I have found several tools that can decode the password, but I have the plaintext. I found a solution using Jython, but I want to use only SQL. There should be a suitable algorithm in the dbms_crypto package, I hope. I don´t want to use other tools or languages.
Thanks for help,
Frank

Desired output is Just remove the Object_type tags and empty tags coming in the output xml.

Generating xml using PL/SQL taking a lot of space in TEMP tablespace

We wrote a stored procedure that generate xml which will be stored in a CLOB column. Environment is 9i on Windows 2003.
The gnerated xml is about 800K. In the procedure there is one big cursor that will retrieve 200 records of 55 fields and many other small dynamic cursors that open and close here and there. The fields are pretty small. Biggest ones are like varchar2(30). The query for the big cursor does using union and need sorting.
Can anyone explain why it takes about 15G of TEMP tablespace to accomplish this job and is there a way to avoid this?

The version is Enterprise Edition 9.2.0.1.0.
Below is the query.

im using win2000 and im connected to ora8.1.6

You should install the XML SQL Utility for PL/SQL in your database. It is basically a set of JAVA classes that get loaded into the database. You will use the PL/SQL packages to access the methods on these classes. You should use the DBMS_XMLQUERY and DBMS_XMLSAVE packages.
You can run the install from your client.

Using a SQL data source and XML data source in the same template

I am trying to develop a template for the Request for Quote report generated in Apps 11.5.10. I have loaded the data from the XML output into the template, but I am missing one field - I need the org_id from the po_headers table. Is it possible to use a sql data source (i.e., "select org_id from po_headers_all where po_header_id = [insert header_id from xml data]...") in addition to the xml data source to populate the template at runtime? When you use the Insert > SQL functionality is it static at the time the template is created, or does it call to the database at runtime? I've looked through all the docs I could find, but this isn't clear.
Thanks for any help or suggestions you may have.

Hi Pablo
Thats a tough one ... if you go custom with a data template you will at least get support on the data template functionality ie you have a problem when you try and build one. You will not get support on the query inside the data template as you might have gotten with the Oracle Report, well you could at least log a bug against development for a bad query.
Eventually that Oracle Report will be converted by development anyway, theres an R12 project going on right now to switch the shipped OReports to data templates. AT this point you'll be fully supported again but:
1. You have to have R12 and
2. You'll need to wait for the patch
On reflection, if you are confident enough in the query then Oracle will support you on its implementation within a data template. Going forward you may be able to swap out your DT and out in the Oracle one without too much effort.

Parse an Aggregate in XML Document using PL/SQL

Hi. I've been successful with parsing a TAG in XML Document stored in CLOB using PL/SQL XML Parser.
However, I need help on how to get the whole aggregate in XML Document stored in CLOB.
sample XML Doc :
<library>
<book>
<title>Oracle Complete Reference</title>
<author>Kevin</Author>
<year>2000</year>
</book>
<video>
<title>Learning C++</title>
<length>2 hours</length>
<video>
</library>
I need a function that will accept an Input which is the aggregate name and will return the aggregate value.
With the sample XML above, say the input is 'VIDEO', the function will return :
<video>
<title>Learning C++</title>
<length>2 hours</length>
<video>
I'll really appreciate any help.

I used such an example to parse several Varchar2 strings in a given DB session:
BEGIN
parser := xmlparser.newparser ;
xmlparser.parsebuffer(parser,xmlout) ;
domdoc := xmlparser.getDocument(parser) ;
xmlparser.FREEPARSER(parser) ;
parser.id := -1 ;
nodes := xslprocessor.selectNodes(
xmldom.makenode(domdoc),
'Positionen/Position') ;
for i in 1 .. xmldom.getLength(nodes) loop
node := xmldom.item(nodes,i-1) ;
-- do s/thing with the node
end loop ;
xmldom.freedocument(domdoc) ;
RETURN(komponenten) ;
EXCEPTION
WHEN OTHERS THEN
if parser.id <> -1 then xmlparser.freeparser(parser) ;
end if ;
if domdoc.id <> -1 then xmldom.freedocument(domdoc) ;
end if ;
RAISE ;
END ;
However, after about 2000 of nodes lists parsed, I get an ArrayIndexOutOfBoundsException from XMLNodeCover. Obviously, I should release the nodes or the nodelist, but I have not found any procedure to do this.

Could we use embedded SQL for XML in .pc ?

Hi,
Can we use embedded SQL for XML in .pc ?
<1> assume we have run SQL statements in Oracle9i:
SQL>create table MY_XML_TABLE
(Key1 NUMBER,
Xml_Column SYS.XMLTYPE);
SQL>insert into MY_XML_TABLE(key1, Xml_Column) values
(1, SYS.XMLTYPE.CREATEXML
('<book>
<chapter num="1">
<text>This is the my text</text>
</chapter>
<book>')
<2> Could we directly translate it in .pc as usually:
<outlined, not exactly)
int emp_number = 1;
XML_Data emprec; /* ?????? */
EXEC SQL SELECT M.Xml_Column.GETCLOBVAL() as XML_Data
INTO :emprec INDICATOR :emprec_ind
FROM MY_XML_TABLE M
WHERE Key1 = :emp_number;
Thanks
MJ

reply by myself.
No problem!!
===============================
int emp_number = 1;
struct emprec{
char feature[1280]
EXEC SQL SELECT M.Xml_Column.GETCLOBVAL() as XML_Data
INTO :emprec INDICATOR :emprec_ind
FROM MY_XML_TABLE M
WHERE Key1 = :emp_number;

BPEL process to Insert XML into DB using pl/sql stored proc

Hi,
We have created a BPEL process in which we are taking input request and store it into Oracle Database using PL/SQL proc.
We have been unsuccessful in doing so because the data stored in table has root element missing.
Has any body done this (insert xml into DB using pl/sql stored proc) successfully ?
We can so this successfully if we do not use stored procedure and store data directly in table.
Regards

I have done this, stored it as a CLOB.
Also I received the payload as an opaque schema, so I had to convert the message from binary into string.
This way the root element doesn't get removed.
cheers

Write / store xml data in Xe and retrieve stored data using pl/sql

Hi to all,
i'm searching a tutorial on:
A - how to write / store xml data in Xe and retrieve stored data using pl/sql
I don't want to use other technologies, because i use htmldb and my best practice is with pl/sql.
I was reading an ebook (quite old maybe) however it's about oracle 9 and it's talking about xmltype:
1 - I don't understand if this is a user type (clob/varchar) or it's integrated in Oracle 9 however i will read it (it's chapter 3 titled Using Oracle xmldb).
Please dont'reply here: i would be glad if someone can suggest me a good tutorial / pdf to achieve task A in Oracle XE.
Thanx

Thank you very much Carl,
However my fault is that i've not tried to create the table via sql plus.
Infact i was wrong thinking that oracle sql developer allows me to create an xmltype column via the create table tool.
however with a ddl script like the following the table was created successfully.
create table example1
keyvalue varchar2(10) primary key,
xmlcolumn xmltype
Thank you very much for your link.

Generating XML using Varray or Pl/SQL table

I am trying to convert an old plsql procedure to generate XML data. The program is getting all the data to report from various sources to a pl/sql table.
Is there any way to directly convert data into xml from plsql table ??
Here is the plsql table defination
TYPE Emp_rec IS RECORD ( Batch_name VARCHAR2(240)
,Employee_name VARCHAR2(240)
,Employee_number VARCHAR2(240)
,Element_name VARCHAR2(240)
,Bee_value NUMBER
,Ele_scr_value NUMBER
TYPE emp_data IS TABLE OF Emp_rec
INDEX BY BINARY_INTEGER;
E emp_data;
And i am trying to get xml using following code:
FOR i IN E.FIRST.. E.LAST
LOOP
SELECT
XMLConcat (
XMLELEMENT(
"batch",
XMLFOREST(
E(i).Batch_name AS "Batch_name",
E(i).Employee_number AS "Employee_number",
E(i).Element_name AS "Element_name"
INTO l_xml
FROM dual;
end loop;
I am not sure whether this can actually be done or not. I have option to write the xml file manually to output ; but just wondering whether this method of getting xml is correct or not ? If yes, then how can we use plsql table data and merge it into a single XML file
Please let me know your views and opinions.
Thanks

How to iterate xml elements using PL/SQL

Hello,
Let's say I have the following xml:
<A>




</A>
I would like to iterate over the B and sub-B elements using PL/SQL?
Any help will be appreciated.

Hi,
You can use 'PL/SQL DOM API for XMLType (DBMS_XMLDOM)'
to work with XML. You can check the example present at
http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920/a96620/xdb08pls.htm#1041419
to check how it does.
The API for the package DBMS_XMLDOM is given on the same page(http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920/a96620/xdb08pls.htm#1040676)
You can use them for your requirement.

Anupama
