一、总结
1. 上传资料
(1).通过调用function<FND_FNDFLUPL>，打开上传文件页面；
(2).从表fnd_lob_access和fnd_lobs中取出文件名放在form画面上；
2. 对dbms_lob中的二进制文件进行处理
(1).通过dbms_lob.converttoclob将二进制文件转换成字符文件；
(2).通过dbms_lob.instr和dbms_lob.substr在字符文件获取字符串记录；
3. 对获取资料放入到临时表，并显示在画面上
(1).通过instr和substr获字符串记录中的字段；
(2).并将字段赋值到集合或表中；
二、步骤
1. 上传资料
1 DECLARE 3 access_id NUMBER; 5 l_server_url VARCHAR2(100); 7 l_parameters VARCHAR2(100); 9 button_choice INTEGER;11 l_file_id VARCHAR2(100); 13 l_gfm_id INTEGER; 15 BEGIN 17 access_id := fnd_gfm.authorize(NULL);19 fnd_profile.get('APPS_WEB_AGENT', l_server_url);21 l_parameters := 'access_id=' || access_id || ' l_server_url=' || l_server_url; 23 fnd_function.EXECUTE(function_name => 'FND_FNDFLUPL', 25 open_flag => 'Y', 27 session_flag => 'Y', 29 other_params => l_parameters); 31 -- Display a modal message for user to indicate file upload 33 -- is completed. 35 fnd_message.set_name('FND', 'ATCHMT-FILE-UPLOAD-COMPLETE');37 button_choice := fnd_message.question(button1 => 'YES',39 button2 => NULL, 41 button3 => 'NO',43 default_btn => 1, 45 cancel_btn => 3,46 icon => 'question');48 49 IF (button_choice = 3) THEN51 NULL; 53 ELSIF (button_choice = 1) THEN 55 l_file_id := '';57 l_gfm_id := fnd_gfm.get_file_id(access_id); 59 :main.gfm_id := fnd_gfm.get_file_id(access_id); 61 IF l_gfm_id IS NOT NULL THEN63 SELECT DECODE(INSTR(file_name, '/'),0,file_name,SUBSTR(file_name, INSTR(file_name, '/') + 1)) 65 INTO l_file_id 67 FROM fnd_lobs 69 WHERE file_id = l_gfm_id; 71 IF l_file_id IS NOT NULL THEN 73 :main.filename := l_file_id;75 SELECT cux_ce_stmt_s.NEXTVAL INTO :main.working_id FROM DUAL; 77 END IF; 79 END IF; 81 END IF; 83 END IF;
2. 对dbms_lob中的二进制文件进行处理
1 DECLARE 3 c_data CLOB; 5 l_data BLOB; 7 l_dest_offset INTEGER := 1; 9 l_scr_offset INTEGER := 1;11 l_lang_context INTEGER := DBMS_LOB.default_lang_ctx; 13 l_warn INTEGER;15 n_offset INTEGER;17 n_clob_size INTEGER; 19 n_pos INTEGER;21 v_buf VARCHAR2(4000);23 BEGIN25 DBMS_LOB.createtemporary(c_data, FALSE, DBMS_LOB.SESSION); 27 SELECT file_data INTO l_data FROM fnd_lobs WHERE file_id = 1501905;29 DBMS_LOB.converttoclob(dest_lob => c_data, 31 src_blob => l_data, 33 amount => DBMS_LOB.lobmaxsize, 35 dest_offset => l_dest_offset, 37 src_offset => l_scr_offset,39 blob_csid => NLS_CHARSET_ID('UTF8'), 41 lang_context => l_lang_context,43 warning => l_warn); 45 n_offset := 1;47 LOOP 49 n_pos := DBMS_LOB.INSTR(lob_loc => c_data, 51 pattern => CHR(10), 53 offset => n_offset,55 nth => 1);57 IF NVL(n_pos, 0) = 0 THEN 59 n_pos := n_clob_size + 1; 61 END IF; 63 v_buf := DBMS_LOB.SUBSTR(lob_loc => c_data, 65 amount => n_pos - n_offset, 67 offset => n_offset); 69 n_offset := n_pos + 1; 71 EXIT WHEN n_pos > n_clob_size; 73 END LOOP; 75 IF dbms_lob.istemporary(l_data) > 0 THEN 77 dbms_lob.freetemporary(l_data); 79 END IF; 81 IF dbms_lob.istemporary(c_data) > 0 THEN 83 dbms_lob.freetemporary(c_data); 85 END IF; 87 END IF;
3. 对获取资料放入到临时表，并显示在画面上
1 DECLARE 3 v_buf VARCHAR2(1000); 5 v_field VARCHAR2(1000); 7 n_delimiter_pos INTEGER; 9 BEGIN 11 v_buf := 'Return Authorization Reference,Adjustment Type,Vendor Number,Site Code- Pay To,Site Code- Ship To,Part Number,Quantity,Subinventory';13 LOOP15 v_field := NULL;17 n_delimiter_pos := INSTR(v_buf, ',');19 IF n_delimiter_pos > 0 THEN 21 v_field := LTRIM(RTRIM(SUBSTR(v_buf, 1, n_delimiter_pos - 1))); 23 v_buf := SUBSTR(v_buf, n_delimiter_pos + 1); 25 ELSIF LTRIM(RTRIM(v_buf)) IS NOT NULL THEN 27 v_field := LTRIM(RTRIM(v_buf)); 29 v_buf := NULL; 31 END IF;33 IF (v_buf IS NULL) THEN35 EXIT;37 END IF; 39 END LOOP; 41 END;
