DBMS_XMLQUERY

I have downloaded the tar xdk_plsql_9_0_1_0_0.tar file and installed
the XDK onto my 8.1.7.2 database on a sun sparc server.
My problem is this , for the user scott the following statement works fine in that it produces the xml output :
select dbms_xmlquery.getxml('select * from emp', 2) from dual;
However when I try to use the same package above as another user trying to generate xml on one of its tables , I get the following error:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
Both user scott and my "test user" have identical privileges, which includes the
JAVASYSPRIV and the JAVAUSERPRIV.
My question is this what do I have to do in order for another user to be able to use the
dbms_xmlquery without getting any problems?

RTFM.
Function DBMS_XMLQUERY.GETXML takes 2 number parameters and returns a CLOB.
If you do a describe on DBMS_XMLQUERY you will find :
FUNCTION GETXML RETURNS CLOB
Argument Name Type In/Out Default?
CTX NUMBER IN
METATYPE NUMBER IN DEFAULT
You have to call DBMS_XMLQUERY.NEWCONTEXT and pass it the SQL statement. This function returns a CONTEXT ( number ) which you use in DBMS_XMLQUERY.GETXML.

Error while executing DBMS_XMLQUERY

I'm using a Function to generate a XML file for the given query.
When the functions calls DBMS_XMLQUERY to access a method named : setXSLT ,where it further calls to p_setXSLT .The error comes in p_setXSLT
The error is:
ORA-29532: Java call terminated by uncaught Java exception: java.lang.NoSuchMethodError
The code in the p_setXSLT is:
PROCEDURE setXSLT(ctxHdl IN ctxType, stylesheet IN CLOB, ref IN VARCHAR2 := null) IS
begin
p_setXSLT(ctxHdl, stylesheet, ref);
end setXSLT;

The correct way to handle this is to use bind variables.
And use DBMS_XMLGEN instead of DBMS_XMLQUERY :
create or replace procedure temp (
p_mtr_id       in varchar2

is

AM I OVERLOOKING SOMETHING? DOES DBMS_XMLQUERY() NOT SUPPORT
XMLFOREST()?

Method DBMS_XMLQUERY.getXML() always inserts " ?xml version = '1.0'? " in output

Method "SYS.DBMS_XMLQUERY.getXML()" seems to always want to prefix "<?xml version = '1.0'?>" to the returned output.
I don't think this is always called for.
I want to extract data from the database as an XML fragment. Outside of the RDBMS, I would then combine multiple fragments together into a larger XML document. If each fragment is prefixed with "<?xml version = '1.0'?>", I have to add logic to strip out this offending line.
I tried method setXslt(). Even when my XSL stylesheet transforms the XML into HTML or TEXT, the output gets prefixed with "<?xml version = '1.0'?>", which I feel is wrong.
Question: Is there any way to instruct DBMS_XMLQUERY to omit "<?xml version = '1.0'?>" ?
Thanks!
Louis

Hi,
Use DBMS_XMLGEN.getXMLType to retrieve the XML data into an XMLType variable.
Then, with getClobVal method, you can convert it to CLOB :
SQL> DECLARE
2    v_xml XMLType;
3    v_lob CLOB;
4 BEGIN
5    v_xml := dbms_xmlgen.getXMLType('select * from scott.emp where rownum = 1');
6    v_lob := v_xml.getClobVal();
7
8    dbms_output.put_line(v_lob);
9 END;

XML Generation Using DBMS_XMLQuery

Hi,
I am generating XML using "DBMS_XMLQuery".
Requirement: To generate blank xml tag(Without data).
e.g : Table XXX has A,B,C,D columns.
I am using SQL : SELECT a AA,b BB,c CC,d DD FROM XXX;
<AA>1 </AA>
<BB>2 </BB>
<CC>3 </CC>
(Note : Columns A,B and C has Values but "d" column does not have value).
Since "D" column doesnot have value,it is not generating XML tag.
So ,How to generate XML tag(e.g <DD> </DD>) without Value?
Any idea,how to achieve the above?
Thanks in advance.
Rgds,
Manoj

You can set the null attribute to true , so that the tag appears in your XML

DBMS_XMLQuery behavior when using stored function within cursor select

Consider the following SQL Statement
select t1.id
, t1.name
, cursor ( select t2.id
from tab t2
where t2.t1_id
= t1.id
and validate(t2.xyz,:bd1)
= 1
from tab t1
where t1.id = :bd2
DBMS_XMLQuery is used to create a context and to bind the appropriate values. In this case 'validate' is a stored function. I get the following error message upon execution:
ORA-29532: Java call terminated by uncaught Java exception:
java.sql.SQLException: Missing IN or OUT parameter at index:: 1
Issuing a similar statement in SQL*Plus works fine. I was wondering whether this is a known issue when using a stored function in the cursor select statement in the context of DBMS_XMLQuery or whether I'm doing something wrong.

Hi Jan,
This problem has been identified and fixed. The fix should be available in the next release. Thank you for bringing this up to our attention.

Generating XML in Parallel Mode-DBMS_XMLGEN/ DBMS_XMLQUERY / SQLX?

Is it possible to generate XML in parallel mode for big result sets using DBMS_XMLGEN or DBMS_XMLQUERY or SQLX?
Thanks

SQL/XML may work. WHat does the showplan output show

"Missing IN or OUT parameter at index:: 1" - dbms_xmlquery vs dbms_xmlgen

It looks like DBMS_XMLQuery doesn't like bind variables among selected columns.
While DBMS_XMLGEN handles them without any problems.
A simple example:
-- xml query - fails
declare
ctx dbms_xmlquery.ctxHandle;
begin
ctx := dbms_xmlquery.newContext(
'select a.*, :r_max the_end from scott.emp a where rownum <= :r_max');
dbms_xmlquery.setBindValue(ctx, 'r_max', 10);
dbms_output.put_line(dbms_xmlquery.getxml(ctx));
dbms_xmlquery.closeContext(ctx);
end;
The error is <ERROR>oracle.xml.sql.OracleXMLSQLException: Missing IN or OUT parameter at index:: 1</ERROR>
-- xml gen - works
declare
ctx dbms_xmlgen.ctxHandle;
begin
ctx := dbms_xmlgen.newContext(
'select a.*, :r_max the_end from scott.emp a where rownum <= :r_max');
dbms_xmlgen.setBindValue(ctx, 'r_max', 10);
dbms_output.put_line(dbms_xmlgen.getxml(ctx));
dbms_xmlgen.closeContext(ctx);
end;

Looks like you need two binds to accomplish your task:
SQL> declare
2     ctx   dbms_xmlquery.ctxhandle;
3 begin
4     ctx := dbms_xmlquery.newcontext('select emp.*, :r_max1 the_end from emp where rownum <= :r_max2');
5     dbms_xmlquery.setbindvalue (ctx, 'r_max1', 4);
6     dbms_xmlquery.setbindvalue (ctx, 'r_max2', 4);
7     dbms_output.put_line (dbms_xmlquery.getxml (ctx));
8     dbms_xmlquery.clearbindvalues (ctx);
9     dbms_xmlquery.closecontext (ctx);
10 end;

Supress of rownum tag in dbms_xmlquery

Hi,
I have created the following scrip which uses dbms_xmlquery utility.
queryctx := dbms_xmlquery.newcontext
('select field1,
cursor(field2,
field3
from temp_table2 t2
where t2.field1 = t1.field1) as Header
from temp_table1 t1
where field1 = :p_field);
dbms_xmlquery.setbindvalue(queryctx,'p_field','12435');
result:=dbms_xmlquery.getxml(queryctx);
Which creates this output file:
<ROWSET>
<ROW num="1">
<Field1>226600</Field1>
<Header>
<Header_ROW num="1">
<Field2>87658</Field2>
<Field3>23456</Field3>
</Header_ROW>
</Header>
</ROW>
</ROWSET>
I need to know how to suppress printing of row tag so that the output file
look like this:
<ROWSET>
<Field1>226600</Field1>
<Header>
<Field2>87658</Field2>
<Field3>23456</Field3>
</Header>
</ROWSET

I see. But I have a cursor in my query and that's where it doesn't work. This is my query:
queryctx := dbms_xmlquery.newcontext
('select field1,
cursor(field2,
field3
from temp_table2 t2
where t2.field1 = t1.field1) as Header
from temp_table1 t1
where field1 = :p_field);
dbms_xmlquery.setbindvalue(queryctx,'p_field','12435');
result:=dbms_xmlquery.getxml(queryctx);
I get this result:
<ROWSET>
<Field1>226600</Field1>
<Header>
<Header_ROW num="1">
<Field2>87658</Field2>
<Field3>23456</Field3>
</Header_ROW>
</Header>
</ROWSET>
And I need to get rid of <Header_ROW num="1"> and </Header_ROW> tags. I don't need those tags for any records at all.

Dbms_xmlquery.getxml problem

It's because of the parameter settings in SQL*Plus. It's just not showing the whole output for you...

Storing Chinese data as clob using dbms_xmlquery

Hi,
I am writing a procedure that creates a query and same is stored as CLOB in a database table. Below is a sample test program for same. I am using UTF-8 to accomodate Chinese data. The CLOB however doesn't contain valid chinese data. Please guide me on what needs to be done....
declare
l_ctx dbms_xmlquery.ctxtype;
l_xml_schema NCLOB;
begin
l_ctx := dbms_xmlquery.newcontext('SELECT * FROM (SELECT "SEC","coretypeid","coreid","Record Type","您ID" FROM (SELECT "您MultiCurrency Object".coreid "SEC","您MultiCurrency Object".coretypeid "coretypeid", "您MultiCurrency Object".coreid "coreid", "您MultiCurrency Object".CoreTypeAssocAliasDescr "Record Type", "您MultiCurrency Object".F_3441961635 "您ID"

WHERE coretypeid IN (3420185025)) "您MultiCurrency Object" )) WHERE 1 = 2');
dbms_xmlquery.setraiseexception(l_ctx, TRUE);
dbms_xmlquery.setsqltoxmlnameescaping(l_ctx, TRUE);
-- dbms_xmlquery.setdateformat(l_ctx, l_xml_sformat);
dbms_xmlquery.setencodingtag(l_ctx, 'ISO-8859-1');
l_xml_schema := dbms_xmlquery.getxml(l_ctx,2);
insert into testingXMLgen values (l_xml_schema);
-- :xml_data := dbms_xmlquery.getxml(l_ctx);
dbms_xmlquery.closecontext(l_ctx);
end;

I have tried UTF-8 encoding set as well. It didn't work toodbms_xmlquery.setencodingtag(l_ctx, 'UTF-8');

Mixed case parsing using DBMS_XMLquery

I have created a view using mixed case column names. However, when I use DBMS_XMLquery to pass the select "column_name" from table_name, it does not parse and does not work. However it works fine with passing 'select * from table_name'. Any idea how a mixed case column can be passed to dbms_xmlquery? Or any idea how a mixed case column name is passed in dynamic sql queries.

I found the problem. It was not with mixed case column names. Rather it was because of the NULL value returns from the sql query which the java procedure for transforming sql was not able to trap and throwing out exception.
However, still it is quite funny. If I use all the columns in the query or do select * , I get back the generated XML. If I just select a few columns, I get the error message
ORA-29532: Java call terminated by uncaught java exception (java.lang.NullPointerException
ORA-06512: at "SYS.DBMS_XMLQUERY" line 206
Any idea
