Reg :DBMS_XMLDOM.DOMDocument Error

Question

Hi all,
I tried to create xml document in the C Drive .
I Created Directory like :
create or replace directory ctemp1 as 'C:\';
GRANT ALL ON DIRECTORY ctemp1 to public;
grant read,write on directory ctemp1 to public;
The code is :
DECLARE
doc DBMS_XMLDOM.DOMDocument;
xdata XMLTYPE;
cursor XMLCUR is select SYS_XMLGEN(XMLAGG(XMLELEMENT("EMPNO", ename))) FROM EMP;
Cursor xmlCurdate is
select SYS_XMLGen(
XMLELEMENT(NAME "UTIMEID",
XMLATTRIBUTES (to_char((sysdate - 1),'yyyymmdd') as "uid",
to_char((sysdate - 1),'mm/dd/yyyy (') || rtrim(to_char((sysdate - 1),'Day')) || ')' as "uiddesc")),
sys.xmlgenformatType.createFormat('UPDATED-XML') ) from dual;
BEGIN
OPEN xmlcur;
FETCH xmlcur INTO xdata;
CLOSE xmlcur;
doc := DBMS_XMLDOM.NewDOMDocument(xdata);
DBMS_XMLDOM.WRITETOFILE(doc, 'ctemp1'||'\'||'alert.xml');
OPEN xmlcurdate;
FETCH xmlcurdate INTO xdata;
CLOSE xmlcurdate;
doc := DBMS_XMLDOM.NewDOMDocument(xdata);
DBMS_XMLDOM.WRITETOFILE(doc, 'ctemp1'||'\'||'updated.xml');
END;
Am Getting the Error like :
Error starting at line 8 in command:
DECLARE
doc DBMS_XMLDOM.DOMDocument;
xdata XMLTYPE;
cursor XMLCUR is select SYS_XMLGEN(XMLAGG(XMLELEMENT("EMPNO", ename))) FROM EMP;
Cursor xmlCurdate is
select SYS_XMLGen(
XMLELEMENT(NAME "UTIMEID",
XMLATTRIBUTES (to_char((sysdate - 1),'yyyymmdd') as "uid",
to_char((sysdate - 1),'mm/dd/yyyy (') || rtrim(to_char((sysdate - 1),'Day')) || ')' as "uiddesc")),
sys.xmlgenformatType.createFormat('UPDATED-XML') ) from dual;
BEGIN
OPEN xmlcur;
FETCH xmlcur INTO xdata;
CLOSE xmlcur;
doc := DBMS_XMLDOM.NewDOMDocument(xdata);
DBMS_XMLDOM.WRITETOFILE(doc, 'ctemp1'||'\'||'alert.xml');
OPEN xmlcurdate;
FETCH xmlcurdate INTO xdata;
CLOSE xmlcurdate;
doc := DBMS_XMLDOM.NewDOMDocument(xdata);
DBMS_XMLDOM.WRITETOFILE(doc, 'ctemp1'||'\'||'updated.xml');
END;
Error report:
ORA-29280: invalid directory path

*Cause:    A corresponding directory object does not exist.
*Action:   Correct the directory object parameter, or create a corresponding
directory object with the CREATE DIRECTORY command.
Please help on this .
Thanks in advence .

Answer 1

When you create objects on the database (tables, views, directories etc.) then by default they are stored in the data dictionary in UPPER case (unless you surround the name with double quotes which is poor practice).
So, in your DBMS_XMLDOM.WRITETOFILE call you need to specify the directory name in UPPER case...
DBMS_XMLDOM.WRITETOFILE(doc, 'CTEMP1'||...... simple as that. ;)
