DBMS_XMLGen.newContext giving ORA_19206

Greetings All,
I am trying to create xml output for a query with where clause as follows.
SELECT *
FROM employees
WHERE name = 'JEFF'
v_ctx = DBMS_XMLGen.newContext(
                       'SELECT *
                        FROM employees
                        WHERE name = ''JEFF''
[pre]
WHERE name = ''JEFF'' is throwing ORA-19206.
I tried -
WHERE name = CHR(39)||JEFF||CHR(39) but still getting ORA-19206.
What is best way to create a condition in where clause having string?
Thanks in advance,

It appears you are missing a couple single quotes. You could use the overloaded function of DBMS_XMLGEN.NEWCONTEXT which takes in a SYS_REFCURSOR. This will make the number of single quotes less confusing (no need to keep escaping them). Try the below:
DECLARE
get_data SYS_REFCURSOR;
v_ctx dbms_xmlgen.ctxHandle;
BEGIN
OPEN get_data FOR SELECT * FROM employees WHERE NAME = 'JEFF';
v_ctx := dbms_xmlgen.newContext(get_data);
END;

Dbms_xmlgen.newcontext query from multiple tables and ||

I have two questions
How do I get a dbms_xmlgen.context to query from multiple tables? I have been able to make it work with using one table only, but not with multiple tables.
And how to get the || (concat) to work within my query for my output to an xml file?
Here is my current query:
create or replace function get_xml return clob is
result clob;
qryctx dbms_xmlgen.ctxHandle;
SELECT DBMS_XMLGEN.getxml('select prefix, suffix, fiscal_yr
FROM rcv.recv_accessions ra
where ra.prefix = 8 and ra.fiscal_yr = 11')xml into result FROM dual;
result := DBMS_XMLGEN.getXML(qryCtx);
This is what I desire:
SELECT DBMS_XMLGEN.getxml('select ra.prefix||'-'|| ra.suffix||'-'|| ra.fiscal_yr accession, ss.date_in, st.test
FROM rcv.recv_accessions ra, ser.sero_samples ss, ser.sero_tests st
where ra.prefix = 8 and ra.fiscal_yr = 11 and ss.raid = ra.id and st.ssid = ss.id')xml into result FROM dual;
On this both the reference to multiple tables and the concat function cause errors.
Thank you

Hi,
for the concat do I use xmlconcat?No, XMLConcat is used to concatenate XMLType fragments.
The || operator will do fine, but you must escape any single quote inside the string :
SELECT DBMS_XMLGEN.getxml(
'SELECT ra.prefix ||''-''|| ra.suffix ||''-''|| ra.fiscal_yr as accession,
        ss.date_in,
        st.test
FROM rcv.recv_accessions ra,
      ser.sero_samples ss,
      ser.sero_tests st
WHERE ra.prefix = 8
AND ra.fiscal_yr = 11
AND ss.raid = ra.id
AND st.ssid = ss.id'
INTO result
FROM dual;Or, use the quoting operator to define a custom string delimiter :
SELECT DBMS_XMLGEN.getxml(
q'{SELECT ra.prefix ||'-'|| ra.suffix ||'-'|| ra.fiscal_yr as accession,
        ss.date_in,
        st.test
FROM rcv.recv_accessions ra,
      ser.sero_samples ss,
      ser.sero_tests st
WHERE ra.prefix = 8
AND ra.fiscal_yr = 11
AND ss.raid = ra.id
AND st.ssid = ss.id
INTO result
FROM dual;BTW, a good practice would be to use bind variables for the query. DBMS_XMLGEN can handle them nicely :
CREATE OR REPLACE FUNCTION get_xml
RETURN CLOB
IS
qryctx   DBMS_XMLGEN.ctxHandle;
v_out    CLOB;
qrystr   VARCHAR2(4000) :=
'SELECT ra.prefix ||''-''|| ra.suffix ||''-''|| ra.fiscal_yr as accession,
        ss.date_in,
        st.test
FROM rcv.recv_accessions ra,
      ser.sero_samples ss,
      ser.sero_tests st
WHERE ra.prefix = :b_prefix
AND ra.fiscal_yr = :b_fiscal_yr
AND ss.raid = ra.id
AND st.ssid = ss.id';
BEGIN
qryctx := DBMS_XMLGEN.newContext(qrystr);
DBMS_XMLGEN.setBindValue(qryctx, 'b_prefix', '8');
DBMS_XMLGEN.setBindValue(qryctx, 'b_fiscal_yr', '11');
-- to generate empty elements if necessary :
DBMS_XMLGEN.setNullHandling(qryctx, DBMS_XMLGEN.EMPTY_TAG);
v_out := DBMS_XMLGEN.getXML(qryctx);
DBMS_XMLGEN.closeContext(qryctx);
RETURN v_out;
END;

for a cursor inside this statement are there any like routines like
DBMS_XMLGen.setRowsetTag(v_ctx, 'orderRequest');
DBMS_XMLGen.setRowTag(v_ctx, 'headerRequest');
for the cursor part inside or do I need to simply use a replace on my XML after?
Thanks in advance!

You can use xmlagg instead of the inner cursor:

3   x varchar2(2000);
4 begin
5    v_ctx := DBMS_XMLGen.newContext('select dname ,
6                                            (select xmlagg(xmlelement("lineNumber",ename))
7                                                   from emp b
8                                                  where b.deptno = a.deptno) "lineRequest"
9                                     from dept a');
10
11    DBMS_XMLGen.setRowsetTag(v_ctx, 'orderRequest');
12    DBMS_XMLGen.setRowTag(v_ctx, 'headerRequest');
13    x := dbms_xmlgen.getxml(v_ctx);
14    dbms_output.put_line(x);

Dbms_xmlgen.newContext Perfomance

Hi All,

Dear All,
I have written the below code to generate xml output in Oracle Apps. The code is working fine for less records. But when CLOB size is more than 32k, then
it giving the ORA-06502 error as fnd_file.put_line(fnd_file.output,v_result) can only write 32k at a time.
Can anyone let me know how to handle this? Any help on this would be highly appreciated.

What you need to do is to chop your CLOB up into smaller strings, something like:
l_size := DBMS_LOB.getlength (l_clob);
IF (NVL (l_size, 0) = 0) THEN
raise_application_error (-20001, 'CLOB is NULL');
END IF;
l_offset := 1;
-- Loop
WHILE (l_offset <= l_size) LOOP
l_char := DBMS_LOB.SUBSTR (l_clob,1,l_offset);
IF (l_char = CHR (10)) THEN
FND_FILE.NEW_LINE(FND_FILE.output, 1);
ELSE
FND_FILE.PUT(FND_FILE.output, l_char);
END IF;
-- Increment Offset.
l_offset:= l_offset+1;
END LOOP;
FND_FILE.NEW_LINE(fnd_file.output, 1);

DBMS_XMLGEN, Carriage Returns XSLT to HTML

Hi,
I am facing an issue using the DBMS_XMLGEN. I have written a function (see under) that receive A SYS_REFCURSOR and return as a CLOB the XML with eventually transformed using a CLOB containing the passed XSLT code.
The goal is to reuse several time this functions being called by other function/procedure (see under a sample of one of my procedure) of my package. Those procure/function being called by the front-end (Cold fusion) to retrieve and output the results. My purpose is to make independent of the front end solution the output generation. Any language that can call an Oracle Procedure/Function would be able to process the result with or without a XSLT.
The issue is the CRLF (chr(10)+chr(13) seems to be lost in the process of the varchar2/clob data type used to generate the XML.
A solution, is to modify the select statement and adding when necessary select ... replace(thefield,chr(10),'<br/>') thefield ... but this would request a post processing which I am trying to avoid.

How to get UTF-8 encoding when create XML using DBMS_XMLGEN and UTL_FILE ?

How to get UTF-8 encoding when create XML using DBMS_XMLGEN and UTL_FILE ?
Hi,
I do generate XML-Files by using DBMS_XMLGEN with output by UTL_FILE
but it seems, the xml-Datafile I get on end is not really UTF-8 encoding
( f.ex. cannot verifying it correct in xmlspy )
my dbms is
NLS_CHARACTERSET          = WE8MSWIN1252
NLS_NCHAR_CHARACTERSET     = AL16UTF16
NLS_RDBMS_VERSION     = 10.2.0.1.0
I do generate it in this matter :
declare
xmldoc CLOB;
ctx number ;
utl_file.file_type;
begin
-- generate fom xml-view :
ctx := DBMS_XMLGEN.newContext('select xml from xml_View');
DBMS_XMLGEN.setRowSetTag(ctx, null);
DBMS_XMLGEN.setRowTag(ctx, null );
DBMS_XMLGEN.SETCONVERTSPECIALCHARS(ctx,TRUE);
-- create xml-file:
xmldoc := DBMS_XMLGEN.getXML(ctx);
-- put data to host-file:
vblob_len := DBMS_LOB.getlength(xmldoc);
DBMS_LOB.READ (xmldoc, vblob_len, 1, vBuffer);
bHandle := utl_file.fopen(vPATH,vFileName,'W',32767);
UTL_FILE.put_line(bHandle, vbuffer, FALSE);
UTL_FILE.fclose(bHandle);
end ;
maybe while work UTL_FILE there is a change the encoding ?
How can this solved ?
Thank you
Norbert

Marco,
I tryed to work with dbms_xslprocessor.clob2file,
that works good,
but what is in this matter with encoding UTF-8 ?
in my understandig, the xmltyp created should be UTF8 (16),
but when open the xml-file in xmlSpy as UTF-8,
it is not well ( german caracter like Ä, Ö .. ):
my dbms is
NLS_CHARACTERSET = WE8MSWIN1252
NLS_NCHAR_CHARACTERSET = AL16UTF16
NLS_RDBMS_VERSION = 10.2.0.1.0
-- test:
create table nh_test ( s0 number, s1 varchar2(20) ) ;
insert into nh_test (select 1,'hallo' from dual );
insert into nh_test (select 2,'straße' from dual );
insert into nh_test (select 3,'mäckie' from dual );
insert into nh_test (select 4,'euro_€' from dual );
commit;
select * from nh_test ;
S0     S1
1     hallo
1     hallo
2     straße
3     mäckie
4     euro_€
declare
rc sys_refcursor;
begin
open rc FOR SELECT * FROM ( SELECT s0,s1 from nh_test );
dbms_xslprocessor.clob2file( xmltype( rc ).getclobval( ) , 'XML_EXPORT_DIR','my_xml_file.xml');
end;
( its the same when using output with DBMS_XMLDOM.WRITETOFILE )
open in xmlSpy is:
<?xml version="1.0"?>

XML File Generation Issues using DBMS_XMLGEN

Hi,
I am using DBMS_XMLGEN package in a stored procedure to generate an XML file on Oracle 10 G R2 .But, the problem is the format in which the file is generated.
CREATE OR REPLACE TYPE "state_info" as object (
"@product_type" Number
CREATE OR REPLACE TYPE prod_tab as TABLE OF "state_info";
CREATE OR REPLACE TYPE state_t as object (
"state_code" CHAR(2),
"state_info" prod_tab
CREATE OR REPLACE PROCEDURE get_xml_serviced_state (p_clob OUT clob)
IS
v_xmlctx DBMS_XMLGEN.ctxhandle;
v_str VARCHAR2 (1000);
BEGIN
v_str := 'SELECT state_t(a.st_cd,CAST(MULTISET(select veh_type_id from svcd_st where st_cd =a.st_cd)as prod_tab)) as "state_info"
from svcd_st a where a.st_cd in (select distinct st_cd from svcd_st) group by a.st_cd having count(*)>=1';
v_xmlctx := DBMS_XMLGEN.newcontext (v_str);
DBMS_XMLGEN.setrowsettag (v_xmlctx,'serviced_state');
DBMS_XMLGEN.setrowtag (v_xmlctx,NULL);
p_clob := DBMS_XMLGEN.getxml (v_xmlctx);
printclobout(p_clob);
EXCEPTION
WHEN NO_DATA_FOUND
THEN
NULL;
WHEN OTHERS
THEN
RAISE;
END;
SHOW ERRORS
Output :

Required it in below format:
<serviced_state>
<state_info state_code="VA">
<state_info product_type="2"/>
<state_info product_type="5"/>
<state_info product_type="9"/>
</state_info>
<state_info state_code="AB">
<state_info product_type="2"/>
<state_info product_type="5"/>
<state_info product_type="9"/>
</state_info>
</serviced_state>
I just need to put in all the rows under one single tag.Appreciate your early responses.
Thanks.

DBMS_XMLGEN not working for me

I'm just starting with this, so I may be missing something.
I have 9.2.0.1.0 installed on Linux Redhat.
I'm trying to create an XML document by querying a table
as described in the Oracle 9i XML Database Developer's Guide, pg 10-28.
I'm querying a very simple table, and it seems to start, but then it creates locks and that is it. I don't get errors, it just doesn't work. Below is what I do/get:
create table xml_test_clob (result clob);
declare
v_result clob;
l_ctx dbms_xmlgen.ctxHandle;
l_sql varchar2(400);
begin
l_sql := 'select * from scott.emp';
l_ctx := dbms_xmlgen.newContext(l_sql);
v_result := dbms_xmlgen.getXml(l_ctx);
insert into xml_test_clob VALUES(v_result);
dbms_output.put_line('testing');
dbms_xmlgen.closecontext(l_ctx);
exception
when others then
dbms_output.put_line('error: '||to_char(sqlcode));
end;
testing
PL/SQL procedure successfully completed.
SQL> select * from xml_test_clob;
RESULT
<?xml version="1.0"?>
<ROWSET>
<ROW>
<EMPNO>7369</EMPNO>
<ENAME>SMITH</ENAM
SQL>
It seems like it just stops, and then I have locks which I have to clear in order to truncate the table to try again.
I'm just in a 'normal' schema. Do I have to do something else to make this work?
Thanks,
Tim

Mark,
Yes I did run catpatch.sql.
when trying to compile dbms_xmlgen, I get:
SQL> alter package dbms_xmlgen compile body;
alter package dbms_xmlgen compile body
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-04045: errors during recompilation/revalidation of LBACSYS.LBAC_EVENTS

ORA-06512: at line 2
ORA-06508: PL/SQL: could not find program unit being called
ORA-06512: at line 2
SQL>
I did a search on metalink and found that LBACSYS is
'Label Security'. I don't recall selecting this to be
installed when I first installed the db.
I found a post on metalink that showed a script, catnools.sql that removes Label Security. Do you think
I should run it?
Is there some way to regenerate dbms_xmlgen (rather than
recompile?)

Using dbms_xmlgen with a CAST statement

The following code populates a plsql collection and then attempts to select from it using dbms_xmlgen.
the following error results --
DECLARE
ERROR at line 1:
ORA-19206: Invalid value for query or REF CURSOR parameter
ORA-06512: at "SYS.DBMS_XMLGEN", line 83
ORA-06512: at line 56
The query is correct as the commented out select at end of block works fine.
Can dbms_xmlgen be used in such a way and if not is there a workaround.
Thanks
DECLARE

create or replace type bus_tab_obj AS object

queryCtx := DBMS_XMLGen.newContext('select a.business_model_name data from THE ( select cast( get_values_pkg.bus_table_recs as bus_table ) from dual ) a order by data');
dbms_xmlgen.setMaxRows(queryCtx,1);
myxml := DBMS_XMLGen.getXMLType(queryCtx);
dbms_output.put_line(myxml.extract('/*').getStringVal());
this works!

loop
dbms_output.put_line( x.data );
end loop;

Thank you all , see I am new to this database field , I am not a pro.Not a problem. However, one of the very first things you should learn is that dynamic SQL is seldom needed and invariably just plain wrong.
If a table name is dynamic, or a column name is dynamic - then chances are excellent that your data model is already fubar'ed (or malema'ed to put it in a za.org perspective).
And even when you are in the very exceptional situation where dynamic SQL is needed, SQL injection is a MAJOR security concern.. and almost always ignored by implementing shoddy code to create and execute the dynamic SQL.

DBMS_XMLGEN --Number of active cursors in increased in Exception block

Hi ,
We have a custom code that use DBMS_XMLGEN,the issue is when any exception happens the Number os active cusrors increse and when it happens in a lopp we hit 1000ORA-01000: maximum open cursors exceeded.
Although I close the context in the exception Block.
Below is sample code where I could replicate this:
Step1.Create a table
CREATE TABLE EMP(EMP_NO NUMBER,EMPNAME VARCHAR2(100));
Step2:
Create a Procedure:
CREATE OR REPLACE PROCEDURE TEST_XMLGEN
AS
l_clob CLOB;
l_ctx         dbms_xmlgen.ctxhandle;
p_sql VARCHAR2(4000):='SELECT EMP_NO,,EMPNAME FROM EMP';--syntax error on purpose ,so that exception happens

           INTO l_cursor_count
           FROM v$mystat a, v$statname b
          WHERE     a.statistic# = b.statistic#
                AND b.name = 'opened cursors current';
        DBMS_OUTPUT.PUT_LINE ('open cursors place00' || l_cursor_count);
l_ctx := dbms_xmlgen.newcontext (p_sql);

                AND b.name = 'opened cursors current';
         DBMS_OUTPUT.PUT_LINE('open cursors place01' || l_cursor_count);
dbms_xmlgen.getxml (l_ctx,l_clob);
SELECT VALUE
           INTO l_cursor_count
           FROM v$mystat a, v$statname b
          WHERE     a.statistic# = b.statistic#
                AND b.name = 'opened cursors current';
         DBMS_OUTPUT.PUT_LINE ('open cursors place02' || l_cursor_count);
DBMS_OUTPUT.PUT_LINE('l_clob:'||l_clob);
dbms_xmlgen.closecontext (l_ctx);
SELECT VALUE
           INTO l_cursor_count
           FROM v$mystat a, v$statname b
          WHERE     a.statistic# = b.statistic#
                AND b.name = 'opened cursors current';
         DBMS_OUTPUT.PUT_LINE ('open cursors place03' || l_cursor_count);

                AND b.name = 'opened cursors current';
         DBMS_OUTPUT.PUT_LINE ('open cursors place04' || l_cursor_count);
dbms_xmlgen.closecontext (l_ctx);
SELECT VALUE
           INTO l_cursor_count
           FROM v$mystat a, v$statname b
          WHERE     a.statistic# = b.statistic#
                AND b.name = 'opened cursors current';
         DBMS_OUTPUT.PUT_LINE ('open cursors place05' || l_cursor_count);
END;
Step3: Execute above Procedure
If you look at the number of active cursor it is increased in exception block,I suspect this is what is causing issue with my program too.Any suggestions to solve this issue.
Thanks

Dbms_xmlgen using pl-sql record type

Hi
I want to pass pl-sql record type and want to generate xml. Can dbms_xmlgen access pl-sql record type instead of query?
OR please let me know any other package to pass pl-sql record type and generate XML.
Thanks in advance

Can dbms_xmlgen access pl-sql record type instead of query?Don't think so, but can't you pass the individual record components:
SQL> declare
type rec is record
    a   int,
    b   varchar2 (30)
r     rec;
ctx   int;
x     xmltype;
begin
r.a := 1;
r.b := 'Michael';
ctx := dbms_xmlgen.newcontext ('select :x id, :y name from dual');
dbms_xmlgen.setbindvalue (ctx, 'x', r.a);
dbms_xmlgen.setbindvalue (ctx, 'y', r.b);
x := dbms_xmlgen.getxmltype (ctx);
dbms_output.put_line (x.getstringval ());
dbms_xmlgen.closecontext (ctx);
end;

Dbms_xmlgen: write emp content to xml file

Hi.
I have the following procedure to write the content of the emp table in xml to a file:
CREATE OR REPLACE PROCEDURE BSP_DBMSXMLGEN IS
v_ctx DBMS_XMLGen.ctxHandle;
v_file Utl_File.File_Type;
v_xml CLOB;
v_more BOOLEAN := TRUE;
l_exception varchar2(2000);
BEGIN
-- XML context erzeugen
v_ctx := DBMS_XMLGen.newContext('SELECT * from emp_big');
-- Root Element und Zeilentag setzen
DBMS_XMLGen.setRowsetTag(v_ctx, 'Emp');
DBMS_XMLGen.setRowTag(v_ctx, 'Zeile');
-- XML Dokument erzeugen
v_xml := DBMS_XMLGen.GetXML(v_ctx);
DBMS_XMLGen.closeContext(v_ctx);
-- Ausgabedatei erzeugen
v_file := Utl_File.FOpen('XML_DIR', 'BSP_DBMSXMLGEN.xml', 'w');
-- In Datei schreiben
WHILE v_more LOOP
Utl_File.Put(v_file, Substr(v_xml, 1, 32767));
IF Length(v_xml) > 32767 THEN
v_xml := Substr(v_xml, 32768);
ELSE
v_more := FALSE;
END IF;
END LOOP;
Utl_File.FClose(v_file);
EXCEPTION
when OTHERS then
l_exception := sqlerrm;
dbms_output.put_line('Error: ' || l_exception);
END;
The procedure works well with 14 emp rows. But after duplicating the rows a few times the procedure stops working...
insert into emp_big select * from emp_big;
commit;
select count(*) from emp_big;
COUNT(*)
960
exec bsp_dbmsxmlgen;
The file content:
<?xml version="1.0"?>
<Emp>
<Zeile>
<EMPNO>7369</EMPNO>
<ENAME>SMITH</ENAME>
<JOB>CLERK</JOB>
<MGR>7902</MGR>
<HIREDATE>17.12.80</HIREDATE>
<SAL>800</SAL>
<DEPTNO>20</DEPTNO>
</Zeile>
<Zeile>
<EMPNO>7499</EMPNO>
<E
The procedure stops writing to file in the middle of a table row...
Any ideas?
Thanks
Markus

Thanks, Marco, but I think I need to be more clear. The original XML data in the XMLType field looks like:
<?xml version="1.0" encoding="ISO-8859-1"?>
<metadata>
</metadata>where "metadata" is the root node of the entire file. What happens is when I run the script listed above, the name of the field being queried gets added as a root node, which I don't want. I did figure out how to omit the "ROW" and ROWSET" nodes from being placed in the resulting XML flat file. Using the same script, I replaced:
-- Root Element und Zeilentag setzen
DBMS_XMLGen.setRowsetTag( v_ctx, 'Emp' );
DBMS_XMLGen.setRowTag( v_ctx, 'Zeile' );with
-- Root Elements
DBMS_XMLGen.setRowsetTag( v_ctx, '' );
DBMS_XMLGen.setRowTag( v_ctx, '' );I simply removed "Emp" and "Zeile." By doing this, those nodes are omitted. I still can't figure out how to omit the "XML_DATA" node.
