附件下载功能

使用 fnd_lobs 表结合 fnd_gfm 包下载文件,可以下载已经存在fnd_lobs表里的文件,也可以手动写些内容进fnd_lobs表,然后在浏览器里显示:
--1.下载fnd_lobs表里已经存在的文件:
DECLARE
  v_file_id   NUMBER ;
    url          VARCHAR2 ( 500   );
BEGIN
    --Get the file_id of the file which you want to download in fnd_lobs
  v_file_id := xxxxxx;
    --Get The Download URL
    url   := fnd_gfm.construct_download_url(fnd_web_config.gfm_agent,
                                        v_file_id,
                                          TRUE );
  fnd_utilities.open_url(   url );
END ;
--2.手动写内容进fnd_lobs表,并在浏览器中显示: DECLARE db_file NUMBER;
mime_type   VARCHAR2 (   255 ) :=   'text/plain'   ;
out_string   VARCHAR2 (   32767 ) :=   'Just some plain text that is stored'   ;
web_server_prefix   VARCHAR2 (   500 );
url   VARCHAR2   ( 500 );
BEGIN
  db_file := fnd_gfm.file_create(content_type => mime_type,
                                 program_name =>   'export' );
  fnd_gfm.file_write_line(db_file, out_string);
  db_file := fnd_gfm.file_close(db_file);
    url      := fnd_gfm.construct_download_url(fnd_web_config.gfm_agent,
                                            db_file,
                                              TRUE );
  fnd_utilities.open_url(   url );
END ;
