download some CLOB contetnt as a file

KostadinJul 14 2018 — edited Jul 17 2018

Hi,

The idea is simply to download some CLOB contetnt as a file on the local machine.

The approach is the same as this  .

My application page  contains only the  PL/SQL procedure  as a process on post rendering , after region.

The content of the CLOB is displayed, not downloaded ?

I need a help to download the content of the CLOB  "SOME TEXT..."

Regards,

Kostadin

The PL/SQL:

Declare

    V_CLOB clob;

    V_BLOB blob;

    v_lang_context  integer := DBMS_LOB.DEFAULT_LANG_CTX;

    v_warning       integer := DBMS_LOB.WARN_INCONVERTIBLE_CHAR;

    v_dest_offset   integer := 1;

    v_source_offset integer := 1;

begin

v_CLOB:= 'SOME TEXT...';

    dbms_lob.createtemporary(v_blob, true, DBMS_LOB.CALL);

    sys.htp.init;

    sys.owa_util.mime_header( 'application/octet-stream', FALSE,'UTF-8' );

    sys.htp.p('Content-length: ' || sys.dbms_lob.getlength( v_clob ));

    sys.htp.p('Content-Disposition: attachment; filename="'||'FILE_NAME.txt'||'"' );

    sys.owa_util.http_header_close;

    dbms_lob.converttoblob (

        dest_lob    => V_BLOB,

        src_clob    => V_CLOB,

        amount      => DBMS_LOB.LOBMAXSIZE,

        dest_offset => v_dest_offset,

        src_offset  => v_source_offset,

        blob_csid   => DBMS_LOB.DEFAULT_CSID,

        lang_context=> v_lang_context,

        warning     => v_warning

    );

   sys.wpg_docload.download_file(v_blob);

   DBMS_LOB.FREETEMPORARY (v_BLOB);

   apex_application.stop_apex_engine;

exception when others then

    sys.htp.prn('error: '||sqlerrm);

   DBMS_LOB.FREETEMPORARY (v_BLOB);

   apex_application.stop_apex_engine;

end;
