在powerBuilder中建立一個Physical Data Model,在其中建立一個使用者表,資訊如所示:

 

 此時的SQL語句可從其中的Preview視圖中得到,如所示:

這個時候產生的sql語句是沒有注釋的,而且sql語句可能也不是適合自己所對應的資料庫語言。此時可以通過以下方法來產生注釋並且選擇所需的資料庫語言。

1、為sql產生注釋,操作如下,我用的是PowerDesigner12.5,在其中選擇Tools----》Excute commands-----》Edit/Run Script開啟的視窗中添加以下資訊

‘****************************************************************************** ‘*   File:           name2comment.vbs ‘*   Purpose:     Database   generation   cannot   use   object   names   anymore   ‘                         in   version   7   and   above. ‘                         It   always   uses   the   object   codes. ‘‘                         In   case   the   object   codes   are   not   aligned   with   your   ‘                         object   names   in   your   model,   this   script   will   copy   ‘                         the   object   Name   onto   the   object   Comment   for   ‘                         the   Tables   and   Columns. ‘‘*   Title:         ‘*   Version:     1.0 ‘*   Company:     Sybase   Inc.   ‘******************************************************************************Option ExplicitValidationMode   = TrueInteractiveMode   =   im_BatchDim   mdl   ‘   the   current   model‘   get   the   current   active   model Set   mdl   =   ActiveModel If   (mdl   Is Nothing)   ThenMsgBox "There   is   no   current   Model "ElseIf Not   mdl.IsKindOf(PdPDM.cls_Model)   ThenMsgBox "The   current   model   is   not   an   Physical   Data   model. "Else      ProcessFolder   mdl End If‘   This   routine   copy   name   into   comment   for   each   table,   each   column   and   each   view ‘   of   the   current   folder Private sub   ProcessFolder(folder) Dim   Tab   ‘running     table for each   Tab   in   folder.tables if not   tab.isShortcut   then                  ‘把表明作為表注釋,其實不用這麼做                  tab.comment   =   tab.name Dim   col   ‘   running   column for each   col   in   tab.columns                         ‘把列name和comment合并為comment                        col.comment=   col.name nextend ifnextDim   view   ‘running   view for each   view   in   folder.Views if not   view.isShortcut   then                  view.comment   =   view.name end ifnext‘   go   into   the   sub-packages Dim   f   ‘   running   folder For Each   f   In   folder.Packages if not   f.IsShortcut   then                  ProcessFolder   f end ifNextend sub

點擊run後,可以看到剛剛的preview視圖視窗中已經如所示

 

2、更換資料庫sql語句。

選擇Database---》change current DBMS,在DBMS中選擇對應的資料庫,如Microsoft SQL Server 2005,點擊確定後,然後選擇Database---》Generate Database選項,在彈出的視窗中選擇產生sql檔案的儲存路徑,點擊確定,則可看到產生的sql語言完全是按照sqlserver2005的標準。
