excel報表解決方法(ebs)

長久以來，oracle執行的excel報表經常採用csv格式，使用者需要view output，然後另存為本地csv檔案，才能用excel開啟，而且不能保留excel格式，包括欄位長度，欄位格式掩碼，以及公式等。

因為專案需要excel檔案包含公式，所以採用以下方案解決。

（1）將格式template檔案在excel中製做，儲存時，選取XML Spreadsheet格式，生成xml 模板檔案，這樣這個檔案可以包含公式等。

（2）採用fnd_file.put_line方式將xml模板檔案輸出，資料列可以依據程式設計要求修改。

（3）建立concurrent program採用XML輸出方式。

（4）這樣使用者在view output時候，瀏覽器可以自動開啟這個excel檔案。

附上package原始碼，本例子在application 11.5.8,和本機excel 2003，ie6.0測試正常

一下為Sample函式包：
create or replace package TEST_XML_PKG is
  procedure main(errbuf            OUT VARCHAR2,
                 retcode           OUT VARCHAR2);
end TEST_XML_PKG;
/
create or replace package body TEST_XML_PKG is
procedure main(errbuf            OUT VARCHAR2,
               retcode           OUT VARCHAR2)
is
