PowerDesigner实用技巧小结

一、ORACLE数据库建模时,因为ORACLE的表名、字段名若是是小写会有必定的麻烦,须要将小写转化为大写?
(1)在打开pdm的状况下,进入Tools-Model Options-Naming Convention,把Name和Code的标签的Charcter case选项设置成Uppercase就能够!
(2)若是仅想在preview这一层实现,也能够选择Database->Edit current database->Script->Sql->Format,有一项CaseSensitivityUsingQuote,它的 comment为“Determines if the case sensitivity for identifiers is managed using double quotes”,表示是否适用双引号来规定标识符的大小写, 能够看到右边的values默认值为“YES”,改成“No”便可!
建议使用方法(1)。
二、在PDM里,发现某些字段的类型不可改?
这多是引用了DOMAIN的缘故,能够双击此列,进行更改。
三、PDM链接的数据库类型更改?
Database-Change/Edit Current Dbms...
四、PD中将Comment-Name拷贝VBS
在使用PowerDesigner对数据库进行概念模型和物理模型设计时,通常在NAME或Comment中写中文,在Code中写英文。Name用来显 示,Code在代码中使用,但Comment中的文字会保存到数据库Table或Column的Comment中,当Name已经存在的时候,再写一次 Comment很麻烦,可使用如下代码来解决这个问题:
代码一:将Name中的字符COPY至Comment中sql

'******************************************************************************

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

            if   not   tab.isShortcut   then 
                  tab.comment   =   tab.name 
                  Dim   col   '   running   column 
                  for   each   col   in   tab.columns 
                        col.comment=   col.name 
                  next 
            end   if 
      next 
      Dim   view   'running   view 
      for   each   view   in   folder.Views 
            if   not   view.isShortcut   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 
--------------------------------------------


         另外在使用REVERSE ENGINEER从数据库反向生成PDM的时候,PDM中的表的NAME和CODE事实上都是CODE,为了把NAME替换为数据库中Table或Column的中文Comment,可使用如下脚本:
代码二:将Comment中的字符COPY至Name中数据库

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 
Private   sub   ProcessFolder(folder) 
On Error Resume Next 
      Dim   Tab   'running     table 
      for   each   Tab   in   folder.tables 
            if   not   tab.isShortcut   then 
                  tab.name   =   tab.comment 
                  Dim   col   '   running   column 
                  for   each   col   in   tab.columns 
                  if col.comment="" then 
                  else 
                        col.name=   col.comment 
                  end if 
                  next 
            end   if 
      next 
      Dim   view   'running   view 
      for   each   view   in   folder.Views 
            if   not   view.isShortcut   then 
                  view.name   =   view.comment 
            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 
-----------------------------------------------------------------------


以上两段代码都是VB脚本,在PowerDesigner中使用方法为:
    PowerDesigner->Tools->Execute Commands->Edit/Run Scripts
将代码Copy进去执行就能够了,是对整个CDM或PDM进行操做
五、如何根据字段的中文NAME,以其汉语拼音首字母取得CODE英文名?
在tools--> execute command 下执行 run script 的VB脚本:
chn_to_ps.vbside

Option Explicit 
ValidationMode = True 
InteractiveMode = im_Batch 

' get the current active model 
Dim mdl ' the current model 
Set mdl = ActiveModel 
If (mdl Is Nothing) Then 
MsgBox "There is no Active Model" 
Else 
ListObjects(mdl) 
End If 

'----------------------------------------------------------------------------- 
' Sub procedure to scan current package and print information on objects from current package 
' and call again the same sub procedure on all children pacakge 
' of the current package 
'----------------------------------------------------------------------------- 
Private Sub ListObjects(fldr) '列出全部的对象 
output "Scanning " & fldr.code 
Dim obj ' running object 
For Each obj In fldr.children 
' Calling sub procedure to print out information on the object 
'DescribeObject obj 
TableSetNameToCode obj 
Next 

' go into the sub-packages 
Dim f ' running folder 
For Each f In fldr.Packages '递归调用列出全部的对象 
'calling sub procedure to scan children package 
ListObjects f 
Next 
End Sub 

'----------------------------------------------------------------------------- 
' Sub procedure to print information on current object in output 
'----------------------------------------------------------------------------- 
Private Sub DescribeObject(CurrentObject) 
if not CurrentObject.Iskindof(cls_NamedObject) then exit sub 
output "Found "+CurrentObject.ClassName+" """+CurrentObject.Name+""", Created by "+CurrentObject.Creator+" On "+Cstr(CurrentObject.CreationDate)   
End Sub 
'常数 值 描述

'vbCrLf Chr(13) & Chr(10) 回车符与换行符。

Private Sub TableSetNameToCode(CurrentObject) 
if not CurrentObject.Iskindof(cls_Table) then exit sub

if not CurrentObject.isShortcut then

CurrentObject.code = "T_"&GetPy( CurrentObject.name)

index1 = index1 + 1 
next 
end if   
    
End Sub 

'//生成汉字串首字母串 
function GetPy(strxx) 
dim i 
dim getpy1 
for i=1 to len(strxx)

output getpy1 
GetPy = getpy1

getpychar = char 
else

end if

output getpychar + "---->" + cstr(tmpp) 
End Function


注:能够根据实际状况须要,对脚本进行微调,如:根据名称生成注释等。
六、在查看编辑表时,能够一次选中多个列,而后对选中列的字段类型、主键等统一操做。
七、逻辑图形的显示
Tools/Model Options选项能够选择图形上是显示Name、Code;
Tools/Display Preferences能够选择图形上显示的项目,如数据类型等;
八、在修改name的时候,code的值将跟着变更
Tools/General Options 打开Dialog将Operating modes中的 Name To Code mirroring 將前面的勾去掉
九、sql语句中表名与字段名前的引号去除
  也能够选择Database->Edit current database->Script->Sql->Format,有一项CaseSensitivityUsingQuote,它的 comment为“Determines if the case sensitivity for identifiers is managed using double quotes”,表示是否适用双引号来规定标识符的大小写, 能够看到右边的values默认值为“YES”,改成“No”便可!,建议使用这种方法

进入Tools-Model Options-Naming Convention,把Name和Code的标签的Charcter case选项设置成Uppercase或者Lowercase,只要不是Mixed Case就行
十、批量生成测试数据
DataBase->Generation Test Data-> 在此项内,可自由选择、设置
十一、根据中文名生成注释(经过4修改一下也能够,但效率过低)
cat Create_Comment_src_chn.vbs测试

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 code 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 
tab.comment = tab.name 
Dim col 'running column 
for each col in tab.columns 
col.comment= col.name 
next 
end if 
next 

Dim view 'running view 
for each view in folder.Views 
if not view.isShortcut 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


十二、PDM或CDM连线添加或删除结点
CTRL+左键单击便可。this
