DBMS_LOB problem

Question

Hi,
I am trying to load an xml file into my xmltable by using one user defined function called "getClobDocument".
Here is the function source code.
create or replace function getClobDocument(
filename in varchar2,
charset in varchar2 default NULL)
return CLOB deterministic
is
file bfile := bfilename('XMLDIR',filename);
charContent CLOB := ' ';
targetFile bfile;
lang_ctx number := DBMS_LOB.default_lang_ctx;
charset_id number := 0;
src_offset number := 1 ;
dst_offset number := 1 ;
warning number;
begin
     dbms_output.put_line('file_name '||filename);
if charset is not null then
charset_id := NLS_CHARSET_ID(charset);
end if;
targetFile := file;
dbms_output.put_line( DBMS_LOB.getLength(targetFile));
DBMS_LOB.fileopen(targetFile, DBMS_LOB.file_readonly);
DBMS_LOB.LOADCLOBFROMFILE(charContent, targetFile,
DBMS_LOB.getLength(targetFile), src_offset, dst_offset,
charset_id, lang_ctx,warning);
DBMS_LOB.fileclose(targetFile);
dbms_output.put_line('char_content '||charContent);
return charContent;
end;
I inserted an xml file called po.xml into the xml tabel .But i selected the data from xml table only one line is isplayed.
The rest of the xml file is not inserted into the xml table.
I am also getting the following error.
"PL/SQL: numeric or value error: host bind array too small"
can anybody tell the reason for it.
cheers

Just for the sake of clarification ... What value are you specifying for p_dir variable?
It should be a directory object created in the database.
It can be created with a command like
CREATE OR REPLACE DIRECTORY BFILE_DIR AS 'e:\middle-east\ssm';
and the user who is going to call the function should have read access on this directory object which can be granted with a command like
grant read on directory BFILE_DIR to FUNCTIONCALLINGUSER;
I hope this helps with what you are trying
Best Regards
