将DW数据窗口导出为EXCEL文件的方法（整理）
生活随笔
收集整理的這篇文章主要介紹了
将DW数据窗口导出为EXCEL文件的方法（整理）
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
本文為摘自csdn論壇帖子收集整理后匯總版本：

鑒于現在很多朋友詢問 pb 數據導出到excel 中的問題，導出去后格式和數據
類型不對了，自己寫了幾個用戶對象，
希望能拋磚引玉,加強技術交流,得到大家的支持。
1. nvo_excel 只要是兩個接口函數
導出數據存儲的數據,可以定義 excel 的標題
public function integer uf_toexcel (datastore ads_data, readonly string as_title)
導出數據窗口的數據,可以定義 excel 的標題
public function integer uf_toexcel (datawindow adw_data, readonly string as_title)
2. 下面是兩個用戶對象的 sru 文件，自己導入到工程中
$pbexportheader$uo_ds_base.sru
$pbexportcomments$數據存儲基類

2.
函數 : uf_initcolumn? 處理 datetime 格式不是很好
case date//,datetime
?? s_datatype = lower(ds_excel.getitemstring(i_cnt,coltype))
?? if s_datatype = datetime then
??? is_columnformat[i_cnt] = yyyy-m-d h:mm
?? else
??? is_columnformat[i_cnt] = yyyy""年""m""月""d""日""
?? end if
3. 這個不是錯誤，可以加強一下功能
//特別指定日期專用格式為 char(10)
?? s_datatype = lower(ds_excel.getitemstring(i_cnt,coltype))
?? if s_datatype = char(10) then
??? is_columnformat[i_cnt] = yyyy""年""m""月""d""日""
?? end if
??
?? //特別指定時間專用格式為 char(8)
?? s_datatype = lower(ds_excel.getitemstring(i_cnt,coltype))
?? if s_datatype = char(8) then
??? is_columnformat[i_cnt] = h""時""mm""分""ss""秒""
?? end if
?? //特別指定日期時間專用格式為 char(19)
?? s_datatype = lower(ds_excel.getitemstring(i_cnt,coltype))
?? if s_datatype = char(19) then

根據代碼，只有 char(8),10,19 才有啊，這是我設計日期，時間等的專用格式

鑒于現在很多朋友詢問 pb 數據導出到excel 中的問題，導出去后格式和數據
類型不對了，自己寫了幾個用戶對象，
希望能拋磚引玉,加強技術交流,得到大家的支持。
1. nvo_excel 只要是兩個接口函數
導出數據存儲的數據,可以定義 excel 的標題
public function integer uf_toexcel (datastore ads_data, readonly string as_title)
導出數據窗口的數據,可以定義 excel 的標題

2. 下面是兩個用戶對象的 sru 文件，自己導入到工程中

2.
函數 : uf_initcolumn? 處理 datetime 格式不是很好
case date//,datetime
?? s_datatype = lower(ds_excel.getitemstring(i_cnt,coltype))
?? if s_datatype = datetime then
??? is_columnformat[i_cnt] = yyyy-m-d h:mm
?? else
??? is_columnformat[i_cnt] = yyyy""年""m""月""d""日""
?? end if
3. 這個不是錯誤，可以加強一下功能
//特別指定日期專用格式為 char(10)
?? s_datatype = lower(ds_excel.getitemstring(i_cnt,coltype))
?? if s_datatype = char(10) then
??? is_columnformat[i_cnt] = yyyy""年""m""月""d""日""
?? end if
??
?? //特別指定時間專用格式為 char(8)
?? s_datatype = lower(ds_excel.getitemstring(i_cnt,coltype))
?? if s_datatype = char(8) then
??? is_columnformat[i_cnt] = h""時""mm""分""ss""秒""
?? end if
?? //特別指定日期時間專用格式為 char(19)
?? s_datatype = lower(ds_excel.getitemstring(i_cnt,coltype))
?? if s_datatype = char(19) then
??? is_columnformat[i_cnt] = yyyy-m-d h:mm
?? end if
根據代碼，只有 char(8),10,19 才有啊，這是我設計日期，時間等的專用格式
