PowerDesigner多用来进行数据库模型设计,具有SQL语句自动生成等功能。当然,也有不少缺点,比如团队分享。
一、设置PowerDesigner模型视图中数据表显示列
1、Tools-Display Preference…
2、窗口左边Category中General Settings下选择Table
3、窗口右边Advanced…
4、窗口左边选择Columns
5、窗口右边List columns中,选择要显示的列
二、设置PowerDesigner设计表时,自动将name列值中的一部分复制到code列
1、把name/code自动复制功能打开。默认是打开的。
Tool-Genneral-Options Dialog-Name to Code mirroring
2、Tools->Model Options....->Naming Convention
3、选中Name,并勾选Enable name/code conversions.
4、选择Name To Code
粘贴脚本代码
脚本1: .set_value(_First, true, new) .foreach_part(%Name%, "‘#‘") .if (%_First%) .delete(%CurrentPart%) .enddelete .set_value(_First, false, update) .else %CurrentPart% .endif .next 这个例子是把Name内容的#号后边的内容当作Code. 脚本2: .set_value(_First, true, new) .foreach_part(%Name%, "‘#‘") .if (%_First%) %CurrentPart% .set_value(_First, false, update) .endif .next 这个例子是把Name内容的#号前边的内容当作Code.
三、从数据库导入数据到PowerDesigner中后,将comment列值复制到name列
运行脚本 Tools->Execute Commands->Edit/Run Scripts(Ctrl Shift X)
‘****************************************************************************** ‘* File: comment2name.vbs ‘* Purpose: 在PowerDesigner的PDM图形窗口中显示数据列的中文注释 ‘* Title: 将字段的comment赋值到字段的name中 ‘* Category: 打开物理模型,运行本脚本(Ctrl+Shift+X) ‘* Copyright:[email protected],2006/07/25 . ‘* Author: foxzz ‘* Created: ‘* Modified: ‘* Version: 1.0 ‘* Comment: 遍历物理模型中的所有表,将字段的comment赋值到字段的name中。 ‘ 在将name置换为comment过程中,需要考虑的问题 ‘ 1、name必须唯一,而comment有可能不唯一。 ‘ 处理办法是如果字段的comment重复,则字段的name=comment+1、2、3... ‘ 2、comment值有可能为空,这种情况下对字段的name不处理。 ‘ 针对oracle数据库,将comment on column 字段名称 is ‘‘;添加到C:/pdcomment.txt文件中。 ‘ 在补充comment完毕后,便于在数据库中执行 ‘****************************************************************************** Option Explicit ValidationMode = True InteractiveMode = im_Batch Dim system, file Set system = CreateObject("Scripting.FileSystemObject") Dim ForReading, ForWriting, ForAppending ‘打开文件选项 ForReading = 1 ‘ 只读 ForWriting = 2 ‘ 可写 ForAppending = 8 ‘ 可写并追加 ‘打开文本文件 Set file = system.OpenTextFile("C:/pdcomment.txt", ForWriting, true) ‘判断当前model是否物理数据模型 Dim mdl Set mdl = ActiveModel If (mdl Is Nothing) Then MsgBox "处理对象无模型" ElseIf Not mdl.IsKindOf(PdPDM.cls_Model) Then MsgBox "当前模型不是物理数据模型" Else ProcessFolder mdl,file End If file.Close ‘****************************************************************************** Private sub ProcessFolder(folder,file) Dim i,j,k i=0:j=0:k=0 ‘列数组,记录字段里不重复的comment Dim ColumnComment() Dim ColumnCommentNumber() ReDim Preserve ColumnComment(i) ReDim Preserve ColumnCommentNumber(i) Dim tbl ‘当前表 Dim col ‘当前字段 dim curComment ‘当前字段comment ‘处理模型中的表 for each tbl in folder.tables if not tbl.isShortcut then if len(trim(tbl.comment))<>0 then ‘可以在这里显示table的comment ‘tbl.name = tbl.name+"("+trim(tbl.comment)+")" end if ‘处理表中的列 for each col in tbl.columns k = 0 curComment = trim(col.comment) if len(curComment)<>0 then ‘遍历相异的comment数组 for j = 0 to i if ColumnComment(j) = curComment then ‘如果找到相同的comment,则相关计数器加1 ColumnCommentNumber(j) = ColumnCommentNumber(j) + 1 k = j end if Next ‘如果没有相同的comment,则k=0,此时ColumnCommentNumber(0)也为0 ‘否则ColumnCommentNumber(k)不为0 if ColumnCommentNumber(k) <> 0 then col.name = curComment & cstr(ColumnCommentNumber(k)) else col.name = curComment ‘ColumnComment(0)、ColumnCommentNumber(0)永远为空 ‘将相异的comment记录添加到数组中 i = i + 1 ReDim Preserve ColumnComment(i) ReDim Preserve ColumnCommentNumber(i) ColumnComment(i) = curComment ColumnCommentNumber(i) = 0 end if else ‘写入文件中 file.WriteLine "comment on column "+ tbl.name+"."+col.code+" is ‘‘;" end if next end if ‘由于不同表的name允许相同,因此此时重新初始化。 ‘因为ColumnComment(0)、ColumnCommentNumber(0)为空,可以保留 ReDim Preserve ColumnComment(0) ReDim Preserve ColumnCommentNumber(0) i=0:j=0:k=0 next Dim view ‘当前视图 for each view in folder.Views if not view.isShortcut then ‘可以在这里显示view的comment ‘view.name = view.comment end if next ‘对子目录进行递归 Dim subpackage ‘folder For Each subpackage In folder.Packages if not subpackage.IsShortcut then ProcessFolder subpackage , file end if Next end sub
四、将name列值复制到comment列
运行脚本 Tools->Execute Commands->Edit/Run Scripts(Ctrl Shift X)
‘把pd中那么name想自动添加到comment里面 ‘如果comment为空,则填入name;如果不为空,则保留不变,这样可以避免已有的注释丢失. Option Explicit ValidationMode = True InteractiveMode = im_Batch Dim mdl ‘ the current model ‘ get the current active model Set mdl = ActiveModel If (mdl Is Nothing) Then MsgBox "There is no current Model " ElseIf Not mdl.IsKindOf(PdPDM.cls_Model) Then MsgBox "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 if trim(tab.comment)="" then ‘如果有表的注释,则不改变它.如果没有表注释.则把name添加到注释里面. tab.comment = tab.name end if Dim col ‘ running column for each col in tab.columns if trim(col.comment)="" then ‘如果col的comment为空,则填入name,如果已有注释,则不添加;这样可以避免已有注释丢失. col.comment= col.name end if next end if next Dim view ‘running view for each view in folder.Views if not view.isShortcut and trim(view.comment)="" then view.comment = view.name end if next ‘ go into the sub-packages Dim f ‘ running folder For Each f In folder.Packages if not f.IsShortcut then ProcessFolder f end if Next end sub
