powerDesigner 從資料庫匯出表結構，並生產excel ，有效
將資料庫中的表匯入到PowerDesigner中並轉為excel文件
1、開啟PowerDesigner12，在選單中按照如下方式進行操作
file->Reverse Engineer->DataBase
點選後，彈出 New Physical Data Model 的對話方塊
2、在General選項卡中
Model name:模板名字，自己命名。
DMBMS ：根據需要選擇，我選擇的是ORACLEVersion 10g
點確定後彈出 Database Reverse Engineering Option 對話方塊
3 Selection選項卡中，選中Using a data source選項
注意如果是第一次匯入資料，需要你先自己配製ODBC資料來源，方法如下：
1）點選 下面 右側的資料庫 連線按鈕，彈出 Connect to a Data Source 的對話方塊
2）選中 ODBC machine data source 選項，點選 Modify按鈕右邊的 Configure 按鈕 彈出Configure Data Connections
3）在 ODBC Machine Data Sources選項卡 下面的工具欄中點選 第二個 資料庫 配置按鈕(Add Data Source(Ctrl+N)) 彈出建立新資料來源視窗 ，選擇檔案資料來源， 選擇相應的資料來源驅動程式（我選Oracle），點下一步（Modify），給資料來源起個名字，選擇伺服器，下一步，輸入相應的密碼
配置完畢 後 點選確定
4，選擇剛剛配置的資料來源，輸入相應的使用者名稱和密碼 即可。 、
選擇需要匯入的表
在PowerDesigner中，shift+ctrl+X，開啟指令碼執行，指令碼如下：
