前言

记录学习成果，以便温故而知新

---

1.建模

（1） physical data model（物理数据模型）

如图新建“physical data model”，model name可以填项目1，选择DBMS。重命名“PhysicalDiagram_1”为基础数据。

（2）建表

如图，在项目上右击，选择“New”，再选“Table”，弹出窗口。

在表的基本属性中输入基本信息。

如图，编辑字段属性，如数据类型，是否主键等。有些字段属性默认是不显示的，如“默认值”属性，需要自行设置，点击图中漏斗状图标设置。

双击字段行，弹出字段详情窗口，如图，可以设置字段备注，字段自增等。

如图预览SQL。

如图，选中表后点击油漆桶图标，可以更改表的填充色；右侧的表格状图标也可以来建表。同时还可以建视图、外键关联等

2.执行脚本

如图，通过菜单“Tools”=>“Execute Commands”=>“Edit/Run Script”来执行脚本。

（1）导出Excel

      SheetList.Columns(3).ColumnWidth = 30
     SheetList.Columns(4).ColumnWidth = 60
   output "end"
End Sub

（2）字段模型名称（name）到备注（Comment）

对于字段没有备注的表，执行以下脚本可以生成备注

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

3.报告（导出Word文档）

如图，通过菜单“Report”=>“Report Wizard”，生成RTF格式报告

4.更改DBMS

如图，通过菜单“Database”=>“ChangeCurrent DBMS”更改DBMS

5.逆向工程（由数据库建模）

（1）SQL脚本方式

先准备好SQL脚本，然后如图，通过菜单“File”=>“Reverse Engineer”=>“Darabase”，弹出新建物理模型窗口，输入模型名称，选择DBMS。


点击“确定”按钮后，弹出逆向工程选项窗口，如图，选“Using script files”选项，点击添加文件按钮，添加SQL脚本文件，点击“确定”按钮，模型与表生成成功。

Options页的File encoding如图设置，防止中文备注乱码。

（2）数据源方式

如图选择数据源，设置登录用户，之前的操作与SQL脚本方式一致。


登录用户的权限一定要恰当，如果用了root用户，则在下图中连系统表都出现了，勾选起来比较麻烦。点击“OK”按钮则开始逆向建模。

本次所用的PowerDesigner匹配的是32位的MySQL ODBC，一开始安装的是64位的，在配置里没有找到选项，改成32位后才出现MySQL选项。
