XMLElement() returns 'XMLTYPE()'
Hi. I'm a newbie to Oracle XML, and I'm having trouble just getting off the ground. I would expect the following SQL statement:
select xmlelement("dummy",dummy) result from dual;
to return
RESULT
<dummy>X</dummy>
but instead it returns
RESULT()
XMLTYPE()
Any idea why?
I'm running Oracle Database version 10.2.0.2.0 and SQL*Plus version 9.0.1.4.0.
Thank you.
Yes, you are using a version of SQL*PLUS (9.1.x) that is linked with pre 9.2 OCI libraries. These libraries do not understand XMLType. Please make sure that you use SQL*PLUS 9.2.0.3.0 or later. I would strongly recommend that you use a SQL*PLUS version that is equal or newer than your database..
BTW
select xmlelement("dummy",dummy).getCLOBVAL() result from dual
should work as this will series the XML into a CLOB on the server and then send the client a CLOB

Result of function returning XMLType truncated in query
Oracle 10.2.0.2.0
myFunc() is a function returning XMLType
The query:
select myFunc() from dual;
return XML about 2Kb
If I try to run the following query:
select XMLElement("Test",(myFunc())) from dual;
then I get a pice of XML with strange symbols at the end (like this L#sП)

Hello, all.
I have a stored function that returns XMLType data to a JSP page, similar to the example in the Oracle XML DB Developer's Guide (13-4). My schema was developed with great help from this forum and is referenced here:Re: unique constraint defined in xsd
My problem is I am getting the following error when I try to access the returned data in the jsp page:
java.lang.ClassCastException: oracle.sql.OPAQUE
at querymaps.jspService(querymaps.jsp:45)
I cannot quite figure out how to get to the returned data.
Here is the stored function and a sample of data the same select statement returns:
CREATE OR REPLACE FUNCTION getMaps(userName varchar2)
RETURN XMLTYPE
AS
xmlDoc XMLTYPE;
BEGIN
SELECT extract(OBJECT_VALUE, '/mapset/map') into xmlDoc
FROM mapsetxml
WHERE existsNode(OBJECT_VALUE,'/mapset['''|| username ||''']')=1;
RETURN xmlDoc;
END;

The JSP scriplet code is nearly right from the sample- I am using a dataSource connection, so I don't know if that is the problem, or not.
<%
Connection conn=null;
CallableStatement stmt = null;
String dSrcName="jdbc/localDS";
String userName="tester";
XMLType xmlRes = null;
InitialContext ctxt = new InitialContext();
DataSource ds = (DataSource) ctxt.lookup(dSrcName);
conn = ds.getConnection();
try {
stmt=conn.prepareCall("{ ? = call getmaps(?)}");
stmt.registerOutParameter(1, OracleTypes.OPAQUE,"SYS.XMLTYPE");
stmt.setString(2, userName);
stmt.execute();
xmlRes = (XMLType) stmt.getObject(1);
if (xmlRes != null) {
String mapString = xmlRes.getStringVal();
out.println("The map xml for :"+userName+" is "+mapString);
} catch (SQLException se) {
out.println(se.getMessage());
} catch (Exception e) {
out.println(e.getMessage());
} finally {
stmt.close();
conn.close();

How to return xmlType from Webservice generated with JDev and PL/SQL
Hi,
I have generated an PL/SQL package that's returning a value as xmlType.
With JDeveloper I'm deploying this package as a webservice. When invoking the webservice from a webbrowser the result looks like:
<?xml version="1.0" encoding="UTF-8" ?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<ns1:testXmltypeResponse
xmlns:ns1="http://app/webservice.wsdl"
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<return xsi:type="xsd:string">
<ROWSET>
<ROW>
<TODAY>12-OCT-07</TODAY>
</ROW>
</ROWSET>
</return>
</ns1:testXmltypeResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The problem is that the <return> tag contains 'xsi:type="xsd:string"'. And now the webservice response is not valid XML because the return value contains XML and not a string.
The solution would be, when invoking the webservice if the xsi:type would be missing from the result tag or would contains xsd:any. I tried editing the WSDL in JDeveloper and changing the type to xsd:any. After deploying and calling the WSDL from the webbrowser it contains this type. But when invoking the method from the webbrowser it still returns xsd:string as type.
How can I get rid of this type in the <return> or change it.
My JDeveloper version is 10.1.3.3.0 The Oracle database and 9iAS are 10.2.
Thanks in advance,
ThijsWhat version are you on?
Works fine for me on my 11g:
SQL> create or replace procedure testxml (clob_out out clob)
2 is
3 l_clob clob;
4 l_ctx dbms_xmlquery.ctxhandle;
5 begin
6 l_ctx := dbms_xmlquery.newcontext ('select * from dual');
7 l_clob := dbms_xmlquery.getxml (l_ctx);
8 clob_out := l_clob;
9 dbms_xmlquery.closecontext (l_ctx);
10 end testxml;
11 /
Procedure created.
SQL>

SQL>
SQL> print vout
VOUT
<?xml version = '1.0'?>
<ROWSET>
<ROW num="1">
<DUMMY>X</DUMMY>
</ROW>
</ROWSET>But definitely you can optimize your proc a bit: Try
create or replace procedure testxml (clob_out in out nocopy clob)
is
l_ctx dbms_xmlquery.ctxhandle;
begin
l_ctx := dbms_xmlquery.newcontext ('select * from dual');
clob_out := dbms_xmlquery.getxml (l_ctx);
dbms_xmlquery.closecontext (l_ctx);
end testxml;

EBS ISG using custom PL/SQL functions that return XMLType
Hi,
We have a custom PL/SQL package that we use for interfacing systems and some of the functions in this package ruturn an XMLType. We want to deploy the package functions as web services through the ISG, but it is not working as expected. When deployed through the ISG, the functions with XMLType return type produce a null response from the ISG (they work fine when called in SQL or PL/SQL; functions with non-XMLTypes work fine).
If we change the return type to CLOB (and use getClobVal() on the XMLType) then we get a response from the ISG, but it changes all the angle-brackets in the CLOB (which is still arbitrary XML text) to < > ...
What is the proper way to get the complex XMLType output through the ISG? Anyone have any more experience?
Thanks,
--WaltAlex,
For the predicate groups that are indexed/stored, the exact operator types (as in equality, inequality, like etc) that are indexed are specified while assigning the default index parameters. In the following example, exf$indexoper is used to specify the list of indexed operators.
BEGIN
DBMS_EXPFIL.DEFAULT_INDEX_PARAMETERS('Car4Sale',
exf$attribute_list (
exf$attribute (attr_name => 'HorsePower(Model, Year)',
attr_oper => exf$indexoper('=','<','>','>=','<='),
attr_indexed => 'FALSE') --- stored predicate group
END;
/You can find more information about exf$indexoper at
http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28419/t_expfilobj.htm#ARPLS153
Could you confirm that you chose to index 'is null' and 'is not null' while assigning the default index parameters ? This information is available in OPERATOR_LIST column of the USER_EXPFIL_DEF_INDEX_PARAMS view.
Hope this helps,

10g XMLTABLE - can I return XMLTYPE col as well as extract specific columns
Hi,
(This is for version 10.2.0.4)
Currently, we have a giant XML column which contains many parts to it. We split those into individual parts via XMLSEQUENCE and then loop through to extract information from two other XMLTYLE columns. I'd like to be able to use XMLTABLE to join the XMLTYPE columns to each other in one SQL statement, as I think it should be more efficient. (We're having issues when the big XML column has 400 or more parts in it - looping and doing extract values on two xmltype columns 400+ times is proving slow going!)
Anyway, what I'd like to do is use XMLTABLE to produce a table-like structure for each column, then join them so that 1st part in col1 = 1st part in col2 = 1st part in col3.
I've looked around at the documentation and google, but I'm getting stuck at one particular point - I would like to return both the XMLTYPE and specific extracted values from that XMLTYPE as part of the XMLTABLE on each column. I just can't seem to find a way to do it.
Here's an example (that I've nabbed from http://thinktibits.blogspot.com/2011/03/oracle-xmltable-example-part-1.html ) that will hopefully explain more clearly what I'd like to do, taking just one column to start with:
CREATE TABLE xml_test
(NOTEBOOK XMLTYPE);
insert into xml_test values ('<?xml version="1.0" encoding="UTF-8"?><Product Type=''Laptop''><Notebook Brand="HP" Model="Pavilion dv6-3132TX Notebook"><Harddisk>640 GB</Harddisk><Processor>Intel Core i7</Processor><RAM>4 GB</RAM></Notebook><Notebook Brand="HP" Model="HP Pavilion dv6-3032TX Notebook"><Harddisk>640 GB</Harddisk><Processor>Intel Core i7</Processor><RAM>6 GB</RAM></Notebook><Notebook Brand="Toshiba" Model="Satellite A660/07R 3D Notebook"><Harddisk>640 GB</Harddisk><Processor>Intel Core i7</Processor><RAM>4 GB</RAM></Notebook><Notebook Brand="Toshiba" Model="Satellite A660/15J Notebook"><Harddisk>640 GB</Harddisk><Processor>Intel Core i5</Processor><RAM>6 GB</RAM></Notebook></Product>');

4 rows selected.What I'd like is to have the COLUMN_VALUE contents from the first select to appear as a column in the second select - is it possible?
At worst case, I could do a join, only that produces a cartesian product because I don't know how to label the rows from within the first query's XMLTABLE (if I used rownum in the query itself, does that guarentee to come out in the same order as the XMLTABLE results? Would part 1 always be labeled row 1, part 2 row2, etc?).
I hope that makes some sort of sense - I'm not up on XML terms, sadly.
ETA: If there's no way of doing this via XMLTABLE, is there any other way of achieving it?

I'm not sure I understand the rest of your requirement.
Do you want to further break the generated XMLType into a set of relational rows, or repeat the operation on different columns from the same base table? -
I'm unable get XML output from the most basic of queries. I'm currently working through the Sql In Xml out document. Everytime i try to output xml i get a list (without errors) of
EMPLOYEE
<Xmltype>
<Xmltype>
<Xmltype>
<Xmltype>
<Xmltype>
for each record. Can anyone help.
Im running 10g release 2.A couple more questions
First, is the XML stored in the table as XMLType column with a schema?
Second, in sqplus, on 10R2, I just ran the following query, try it and see if what you get.
select xmlforest(object_name as "name") from user_objects where object_type = 'TABLE' and rownum < 5;

Help using Java to retrieve XMLType returned from PL/SQL stored object
Hi,
Please bear with me if this is a trivial question. I'm brand new to Java, JDBC, and XML DB. I've been spinning my wheels on this for a few hours now.
I have a table:
XMLDB_USER@xmldb64> desc my_test_table
Name Null? Type
ID NUMBER(9)
DOC SYS.XMLTYPE(XMLSchema "http:
//www.myproquest.com/Global_
Schema_v3.0.xsd" Element "RE
CORD") STORAGE BINARYI've written a trivially simple PL/SQL function to retrieve the DOC column, based on the ID passed to it.
create or replace function get_doc(goid in number) return xmltype is
doc_content xmltype;
begin
select doc into doc_content from my_test_table where id = goid;
return doc_content;
end;
/Up to here, everything works fine. I wrote a small anonymous PL/SQL block, and proved that I can call the PL/SQL function successfully.
Now, I want to implement in Java. This is where I get confused.
Currently my code looks like this:
import java.sql.*;
import oracle.jdbc.*;
import oracle.jdbc.OracleTypes;
import oracle.jdbc.pool.OracleDataSource;
import oracle.xdb.*;
import java.io.*;
import java.lang.StringBuilder;
import java.sql.Clob;
class MyJava
public static void main(String args[]) throws SQLException, IOException
Clob xml = null;
System.out.print("Connecting to the database...");
System.out.flush();
OracleDataSource ods = new OracleDataSource();
String URL = "jdbc:oracle:thin:@//pqhdb201.aa1.pqe:1522/xmldb64";
ods.setURL(URL);
ods.setUser("xmldb_user");
ods.setPassword("xmldb_user");
Connection conn = ods.getConnection();
System.out.println("connected.");
System.out.println("GOID to be retrieved is " + args[0]);
CallableStatement cs1 = null;
try {
cs1 = conn.prepareCall( "{? = call get_doc (?)}" );
cs1.registerOutParameter(1,OracleTypes.OPAQUE,"XMLType");
cs1.setString(2,args[0]);
cs1.execute();
// xml = XMLType.createXML(cs1.getOPAQUE(1));
xml = (Clob) cs1.getObject(1);
// System.out.println(((XMLType)xml).getStringVal());
// System.out.println(xml.getClobVal());
System.out.println(xml.getCharacterStream());
finally {
if(cs1!=null) cs1.close();
if(conn!=null) conn.close();
}This compiles, but when I run, I get:
pqhdb201:[xmldb64]:(/home/oracle/xmldb_scripts):$java MyJava 91455713
Connecting to the database...connected.
GOID to be retrieved is 91455713

My problem, I think, is that I have a fundamental disconnect somewhere. Objects? Types? Different methods? getClobVal? getStringVal? getCharacterStream? I'm still trying to get up to speed on all the lingo and terminology, and, as a result, I suspect I'm asking the wrong questions, and getting wrong results.
Based on the simple example above, my table and PL/SQL function definitions, can someone help me fill in the gaps of what I'm missing in terms of the Java code?
Thanks!

How do i add a root node to a XMLType
Hi all
I have a problem inserting a root node in a xml document generated by DBMS_XMLGEN.newcontextfromhierarchy. The function get_site_map_nodes generates a document like this:
<?xml version="1.0"?>
<siteMapNode f_page_id="1" title="rot" PATH="1">
<siteMapNode f_page_id="2" title="1.1" PATH="1.1">
<siteMapNode f_page_id="4" title="1.1.1" PATH="1.1.1"/>
</siteMapNode>
<siteMapNode f_page_id="3" title="1.2" PATH="1.2"/>
<siteMap/>
</siteMapNode>
This is correct but i want to add a root node so the result shows as below:
<?xml version="1.0"?>
<siteMap>
<siteMapNode f_page_id="1" title="rot" PATH="1">
<siteMapNode f_page_id="2" title="1.1" PATH="1.1">
<siteMapNode f_page_id="4" title="1.1.1" PATH="1.1.1"/>
</siteMapNode>
<siteMapNode f_page_id="3" title="1.2" PATH="1.2"/>
<siteMap/>
</siteMapNode>
</siteMap>
The problem is that i have no clue how to accomplish this.

I seem to be running into a limit on the size of the CLOB returned from a select into an XMLType. When it gets around 275K it doesn't return a value anymore - it does not return an error, just the .getclobval is empty. I am using the Select XMLAgg(XMLElement) Into XMLType method. Using 9.2 ORA DB running on UNIX. If anybody knows if there is actually a limit, it would be greatly appreciated. I know I can use the dbms_xmlgen method but I want to avoid that if possible.
The full stored proc text:

SELECT XMLTYPE('<OUTER><INNER>TEST</INNER></OUTER>') FROM DUAL;
SELECT XMLELEMENT("OUTER", XMLELEMENT("INNER", 'TEST')) FROM DUAL;
SELECT XMLELEMENT("OUTER", XMLAGG(XMLFOREST('TEST' "INNER"))) FROM DUAL;
SELECT XMLQUERY('/OUTER' PASSING XMLTYPE('<OUTER><INNER>TEST</INNER></OUTER>') RETURNING CONTENT) FROM DUAL;
1 and 2 return the xml string in the result grid column. 3 and 4 return (XMLTYPE) with no data in the pop-up editor when double clicking the result. I changed #3 to:
SELECT XMLELEMENT("OUTER", XMLFOREST('TEST' "INNER")) FROM DUAL;
and it returns the XML string.
I used undo to revert back to my original #3 and it started showing the XML string instead of (XMLTYPE) previously observed.
I changed my connection to another schema, ran #3 again, and it went back to (XMLTYPE). I tried to recreate the same behavior using the 2nd schema, but I was unable to get to show the XML string.
In any test case where I was getting the (XMLTYPE), I was not able to see data in the pop-up editor.

Most often, you get this type of error with CURSOR expression when it does not return any row, then the XMLType constructor fails.
But it's hard to say here as you don't provide sample data.
It looks like you want to aggregate rows coming from the CURSOR subquery. It's better to use XMLAgg function in this case.
Something like :
SELECT xmlelement("worflowAGMT",
( SELECT xmlagg(

Query or procedure reformatting xmltype (clob)
help me out with this one, please. I have not been able to narrow it down:
platform: Ora 9.2.0.5 on AIX, accessed remotely, character set AL32UTF8.
Table with multiple of columns, 2 SYS.XMLTYPE columns (storage CLOB, not compiled schema (xsd:datetime timezone issues)).
One column is a digitally signed xml doc; must be image consistent (char for char).
test 1:
select digitalsignedxml from table where ....;
result is identical to input; life is good.
test 2:
select XMLeleement("digitallysigneddoc", digitallysignedxml) from table where ....;
the body is still identical to the input (ignoring the wrapper), life is good.
test3:
same query as 2, but in a packaged function that is returning XMLTYPE.
The body is not identical, but reformatted. sigh. life is not good.
I have not been able to pin (narrow) this down. I have verified identical, not identical using sqlplus (set long 20000 linesize 20000 header off) and with the team's java application.
???The problem appears to be that "SELECT xmltype_column" from table (XMLTYPE on clob) returns the data as is with no reformatting, and "SELECT XML("wrapper", xmltype_column) from table will totally reformat the xml in the column. Even though the data is stored in CLOB, it is no longer image consistent. yeah, it is still DOM consistent, but if we are dealing with a digitally signed doc, then how can I include that digitally signed doc in a larger XML doc, and still have it valid?
here are teh test cases:
REM for posting purposes I put ";" at all eol (if not already there).
environment: server 9.2.0.5 on AIX
client: sqlplus 9.2.0.5.0 also on AIX (remote, not ORACLE_SID)

XMLType - client problem on reading XML?
When I execute this function in my 9.2.0.7.0 database:
create or replace function get_study_xml (p_study_id in number)
return xmltype is xml_doc xmltype;
begin
execute immediate '
select xmlelement(
...lots of code...
from XML_STUDY_VIEW where STUDY_ID = '||p_study_id||'' into xml_doc;
return xml_doc;
end get_study_xml;I get the following error with a 9.2.0.1.0 client:
ORA-03118: two-task coroutine has invalid stateAnd the following error with a 9.2.0.3.0 client:
ORA-21500: internal error code, arguments: [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s]And finally the following error with a 9.2.0.7.0 client:
ORA-24909: call in progress. Current operation cancelledI've done lots of investigation, and so far I've deduced the following:
* It works fine on a PC with a 10g client
* The function returns the XMLType successfully (it seems)
* On all clients, the error occurs not on returning the XMLType, but on trying to read the XML within.
I am trying to do this via Delphi components from Allround Automations (makers of PL/SQL Developer). I don't know how to output the XML to DBMS Output, so could do with some help there. If I could test it without using Allround's components, I could isolate the problem.
I suspect the problem is not with the components though but with the OCI/client, because the same components work fine on 10g client.
If someone could help give some suggestions, including how I could try to output the XML in SQL*Plus, it would be greatly appreciated.
Best regards,
Gary
I don't know if it's relevent, but it may be worth noting that the SQL statement I've commented out is fairly massive, but even if I query data that produces a tiny XML object (i.e. hardly any data), it still fails. The full function is below, so you can see what I'm doing:

Getting back to the basic problem. Can you reproduce the problem with by calling your PL/SQL from a 9.2.0.7.0 SQL*PLUS.
I'm not familar with Delphi. Is it Java or 'C' based. Is it using an OCI connection. If so does it bind to the latest Oracle Installation or does it embed the Oracle OCI components. If the later do you know which version of OCI is embedded ?
