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.
SELECT ROWNUM + ( SELECT NVL(MAX(WQX_ACTIVITY_GEN_ID), 0) FROM WQX_ACTIVITY ) as WQX_ACTIVITY_GEN_ID
     , A.ACTIVITYIDENTIFIER2            as ACTIVITY_IDENTIFIER

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

Generating XML through PL/SQL

Hi everyone,
I got a new task at work, and my task is to generate XML through PL/SQL.
I am using Oracle 11g database, and SQL Developer 3.0.
The purpose of this procedure is to upload xml file to a queue, so my BPEL process can access the queue and do what it does.
This is my first time writing a procedure that generates xml so bear with me.
Below is a sample of the xml file I received. I need to generate xml file below through PL/SQL. All the information in xml file will need to be retrieved from the database.
I need your help to start working on this procedure. Your help is very much appreciated.

Rooney,
First of all, I would use Oracle package UTL_DBWS to handle web service calls.
But if you choose to do all the work yourself to call web service, this is one of the options:
Since the size of your xml soap request is about 4k, you can just use pl/sql varchar2 variable to construct your xml.
Example:
cSoapRequest VARCHAR2(5000);
BEGIN
cSoapRequest := '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
                         <soap:Body xmlns:ns1="http://www.ussc.gov/soa/casefile/event/types">
                         <caseFileUploadEvent xmlns:xsi="http://www.w3XX.org/2001/XMLSchema-instance"
                         xsi:schemaLocation="http://www.XXXX.gov/soa/casefile/event/types ../xsd/Case_META.xsd"
                         xmlns="http://www.XXXX.gov/soa/casefile/event/types">';
FOR recRow IN <your cursor> LOOP
    cSoapRequest := cSoapRequest || '<dateOfBirth>'|| TO_CHAR(recRow.DOB,'YYYY-MM-DD HH:MI' )|| '</dateOfBirth>';
END LOOP;
...Then use package utl_http to send the request and recieve response.
Google pl/sql webservice,
Here is one:
Calling Web Service from PL/SQL (ORA-31011: XML parsing failed)
Hope this will give you an idea.

How to generate XML file from SQL file !

I am new to XML publisher. I known one way to generate XML file is register one report file in concurrent manager.
But I want to generate XML file from sql file.
Could someone show me how to code in sql file, how to register is in concurrent manager.
Thanks !

Hi
Phew ... not sure we have the space here. So I can point you in the right direction:
1. XML data generation - there are two packages in the db you can use with a plsql procedure, XMLGEN and SQL XML. You can also use java APIs too. Try checking the db documentation and search for the above methods.
2. Registering the report - the system administrators guide will provide this info. Hooking the program up with XMLP is covered here - http://www.oracle.com/technology/products/applications/publishing/resource/CM%20Whitepaper5.0.pdf

How to append the declaration tags to generated xml using Xquery

Hi,
How to append the declaration tags to generated xml using Xquery.generated XML is like
<ROOT>
<CHILD1></CHILD1>
<CHILD2></CHILD2>
</ROOT>
Here I want to append the <?xml version="1.0" encoding="ISO-8859-1"?> and the result xml should be
<?xml version="1.0" encoding="ISO-8859-1"?>
<ROOT>
<CHILD1></CHILD1>
<CHILD2></CHILD2>
</ROOT>
Can anybody help to do this.
Thanks
Mani

First assign this element to a temp variable
<ROOT>
<CHILD1></CHILD1>
<CHILD2></CHILD2>
</ROOT>
Now in XQuery expression create a new variable
<?xml version="1.0" encoding="ISO-8859-1"?>
$temp

Generating XMLs using queries

Hi All,
We have a situation as in where we have to generate a XML out of Oracle UCM. I want to know is there any way where i can generate XML using the reaultset of some query.
Any inputs will be useful..
Thanks.

Hi!
In IdocScript, you can work with the resultset and generate XML as you want ....
You could also make your own java component that would generate XML.

When round tripping with photoshop cc, i get a saved psd file with my original raw,the problem is these are high file sizes and taking a lot of space,can i stop this?

when round tripping with photoshop cc, i get a saved psd file with my original raw,the problem is these are high file sizes and taking a lot of space,can i stop this?

That's not the workflow that I use. I have my Lightroom preferences set to create TIF images when going to Photoshop. I keep the original raw file and the TIF image (usually reduced to an 8-bit image) and only export JPEG's when they are needed to send to a lab or to send to someone over the Internet. JPEG files are highly compressed. I only create them when they are needed, and they are discarded as soon as they have been used for their intended purpose. I keep the raw file and the Photoshop-created TIF in my library. This requires extra disk space. But I always have the highest quality files available.

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

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

How do I generate XML using internal variables in a procedure

I know there is a way to generate XML inside a procedure by querying the database such as
SELECT XMLELEMENT("Emp",
XMLFOREST(e.employee_id, e.last_name, e.salary))
"Emp Element"
FROM employees e WHERE employee_id = 204;
Emp Element
<Emp>
<EMPLOYEE_ID>204</EMPLOYEE_ID>
<LAST_NAME>Baer</LAST_NAME>
<SALARY>10000</SALARY>
</Emp>
What I have unsuccessfully been trying to do is to basically do the same thing except using internal variables like
DECLARE
l_keytype CONTACTINFO.KEYTYPE%TYPE;
l_keyvalue CONTACTINFO.KEYVALUE%TYPE;
l_pricetag CONTACTINFO.PRICATEG%TYPE;
l_xmlout CLOB;
BEGIN
l_keytype := '1';
l_keyvalue := '3333';
l_pricetag := '10';
SELECT XMLELEMENT("ParamSet", .........................this is line 13
XMLFOREST(l_keytype as "keytype", l_keyvalue as "keyvalue", l_pricetag as "pricetag"))
"ParamSet Element"
INTO l_xmlout FROM DUAL;
DBMS_OUTPUT.PUT_LINE('l_xmlout = ' || l_xmlout);
end;
What I'd like it to generate is
<ParamSet>
<KEYTYPE>1 </KEYTYPE>
<KEYVALUE>3333</KEYVALUE>
<PRICETAG>100</PRICETAG>
</ParamSet>
But what I get is a compile error
Error report:
ORA-06550: line 13, column 19: (line 13 is SELECT XMLELEMENT("ParamSet", )
PL/SQL: ORA-00932: inconsistent datatypes: expected NUMBER got -
ORA-06550: line 13, column 1:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause:    Usually a PL/SQL compilation error.
*Action:
Also, I've been told that one issue with XMLFOREST is that if the value is null it won't generate the XML for it. Not good. I will still need the XML even if it is empty. Please help.

Darn, Marc beat me. Here was my answer showing an alternative for returning an XMLType, since that is what the query returns as he said.
DECLARE
   l_keytype    VARCHAR2(5);
   l_keyvalue   VARCHAR2(5);
   l_pricetag   VARCHAR2(5);
   l_xmlout     CLOB;
   l_xmltype    XMLTYPE;
BEGIN
   l_keytype := '1';
   l_keyvalue := '3333';
   l_pricetag := '10';
   SELECT XMLELEMENT("ParamSet",
             XMLFOREST(l_keytype as "keytype",
                       l_keyvalue as "keyvalue",
                       l_pricetag as "pricetag")).getClobVal()
     INTO l_xmlout
     FROM DUAL;
   DBMS_OUTPUT.PUT_LINE('l_xmlout = ' || l_xmlout);
   SELECT XMLELEMENT("ParamSet",
             XMLFOREST(l_keytype as "keytype",
                       l_keyvalue as "keyvalue",
                       l_pricetag as "pricetag"))
     INTO l_xmltype
     FROM DUAL;
   DBMS_OUTPUT.PUT_LINE('l_xmlout = ' || l_xmltype.getClobVal());
end;Here is a link to Oracle's on-line documentation

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.

Generate XML using package xmlgen

I have the following query:
select employ_id, last_name, first_name, salary from employ;
I need generate xml like this:
<row>
<employ>
<employ_id last_name="Dennis" First_name="david">1</employ>
<salary>6</salary>
</employ>
</row>
How can I get it using xmlgen package? Thanks.

No, you will not be able to do that. The
problem is that the columns of the db table
are mapped to XML elements rather then
attributes. Your best bet at achieving your
goal is that after you get your xml document
from the XSU, you transform it using XSLT.
The Oracle Parser does include the xsl processor.
visar
ps.: Today, when using XSU's java API, you can directly get a DOM tree representation of the XML document, which then you can pass directly to the XSL processor and transform it; unfortunately, the PL/SQL API (i.e. xmlgen) doesn only return a string (i.e. lob) representation of the XML doc. So you have to use the PL/SQL Parser to parse it, get it in the DOM format, and only then can you transform it. The good news is that I was assured that in the future the XMLGEN will have a call to get the XML doc in DOM rep.

Generating XML Using JAVA

How to generate XML usng java without using following.
import org.apache.xerces.dom.DocumentImpl;
import org.apache.xml.serialize.OutputFormat;
import org.apache.xml.serialize.XMLSerializer;
XML to be generated is as follows.
<?xml version="1.0" encoding="UTF-8"?>
<Modi xmlns:xsi="Modi/Modi1">
<docConfig>
<className>PO</className>
<classDesc>Purchase</classDesc>
<create>Y</create>
</docConfig>
<indexConfig>
<index sequence="1">
<shortName>PODATE</shortName>
<displayName>PO Date</displayName>
<type>date</type>
<length>10</length>
</index>
</indexConfig>
</upload>

Two answers.
If you want to not use any of the XML-oriented classes, you can use a PrintWriter. Just code:
PrintWriter pw = new PrinteWriter(whatever);
pw.println( "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" );
etc.If you want to use XML-oriented classes, but just not these 3 (can't imagine why), then use
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
instead of XMLSerializer and OutputFormat, and
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
instead of the DocumentImpl

can we rewirte it to get the desired out put ..
Desired output is Just remove the Object_type tags and empty tags coming in the output xml.
The previous issues i mentioned are not solved yet . actually will update the challenges ..
Odie .. thanks.. again
