when I ran below store procedure then it shows error. here some special char related issue ,so i cant generate xml file , here xml format same as generate XML from oracle tables
Connecting to the database DB_old.
ORA-29285: file write error

i am not able to handle some special char like : & / ; :/ . etc please help
The ORA-29285: file write error
isn't the same character-conversion error you referred to before, which was ORA-31061: XDB error: special char to escaped char conversion failed
. It really isn't clear which error you're getting; if it's the file one then the character conversion isn't relevant.
When I run your version of my code against my table, it works OK for smaller tables, and gets ORA-06502: PL/SQL: numeric or value error
if result
is more than 32k characters; or ORA-29285
if there is more than 32k without a line break. You've lost the looping over the clob
to write it to the file in chunks. To output larger values, as I did before:
position pls_integer := 1;
chars pls_integer := 32767;
...
while position < dbms_lob.getlength(result) loop
utl_file.put(v_file, dbms_lob.substr(result, chars, position));
utl_file.fflush(v_file);
position := position + chars;
end loop;
Not sure why you have an inner block ( declare
/ begin
/`end') within the procedure.
If you are getting the ORA-31061
then I'm still unclear which data is causing you a problem, but assuming that the NOTES
transformation you're doing solves that and you're still seeing ORA-31061 when you call this for your LOGFILE
table, then that's probably because you reset qryCtx
.
You're creating that at line 23 in the code you provided as:
qryCtx := dbms_xmlgen.newContext ('select LOG_ID,
USER_ID,RUN_DATE,PROCESS,MPOID,MODE_,STATUS,
regexp_replace(unistr(NOTES), ''[[:punct:]]'','''') as NOTES,
MARKDELETED from logfile' );
... but then after the if
/ elsif
/ else
block where you do that, you then overwrite it at line 39 with:
qryCtx := dbms_xmlgen.newContext ('SELECT * from '||V_TABLE_NAME ||'' );
So when you then call getXML(qryCtx)
you aren't getting the modified values for NOTES
.
