前几天研究了一下,然后已经可以正常开发了,今天突然生成出来的sql跟以前不一样了,各种问题。
发生的原因是因为从PDM逆向的生成CDM,然后好像是生成sql的配置也一起被设置了,怎么都调不回来,重装之后正常。
总的来说powerdesigner 设计结构还是很方便的可以直接导出。
1: 设置不自动同步
2:
在生成为物理数据模型时出现错误“The generation has been cancelled because errors have been found by the check model.”
其实也是设置问题,点击PowerDesigner工具栏中的 Tools -> Model Options ->
在Model Settings中按照如下图设置即可。
3:生成PDM
4:选中生成的PDM 选择上路的execute commands-》edit/run 运行下面代码NAME可以直接当作sql注释
‘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
5:然后拿到生成的sql 数据库运行就好了。
