1、连接postgres生成pdm
直接连postgres数据库生成的可以生成表名，但表结构为空，不知为何，后来直接用生成数据库sql脚本后转成pdm成功。但是列注释没有了。
2、sql语句生成的pdm时增加列注释
在PD的 tools-->resources-->dbms-->pg9.x 打开DBMS属性窗口，按下图
在comment on column %TABLE%.%COLUMN% is
%.q:COMMENT%
前添加 [%QUALIFIER%]，如上图保存后再重新生成即可。
3、pdm中列表和注释之间转换的脚本
在【Tools】-【Execute Commands】-【Edit/Run Script】 下。输入下面你要选择的语句即可。
需要注意的问题是：运行语句时必须在Module模式下，如果是导出报表时执行会出现错误提示。
（1）Name转到Comment注释字段。一般情况下只填写NAME，COMMENT可以运行语句自动生成。
'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
（2）将Comment内容保存到NAME中，语句为：
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
