PowerDesigner使用VBScript把表结构导出为Excel

前面有篇文章介绍了如何把Excel编写好的表结构导入到PowerDesigner（见链接：PowerDesigner从Excel导入表结构），在实际的工作中，这两者的互相转化，是经常的事情。

这里给出对应于那篇文章中约定好的Excel格式的导出脚本：

If (Model Is Nothing) Or (Not Model.IsKindOf(PdPDM.cls_Model)) Then
  MsgBox "The current model is not an PDM model."

 ' Get the tables collection

 DIM EXCEL, SHEET
 set EXCEL = CREATEOBJECT("Excel.Application")
 EXCEL.workbooks.add(-4167)'添加工作表

 '设置列宽和自动换行

   Dim tab
   For Each tab In mdl.tables
      ShowTable tab,sheet
   Next
   if mdl.tables.count > 0 then
        sheet.Range("A" & beginrow + 1 & ":A" & rowsNum).Rows.Group
   end if

      ' Show properties
      sheet.cells(rowsNum, 1) = tab.name
      sheet.cells(rowsNum, 2) = tab.code
	  sheet.Range(sheet.cells(rowsNum-colsNum+1,1),sheet.cells(rowsNum,2)).Borders.LineStyle = "1"
	  sheet.Range(sheet.cells(rowsNum,1),sheet.cells(rowsNum,2)).Font.Size=20

	  
	  rowsNum = rowsNum + 1
      sheet.cells(rowsNum, 1) = "字段含义"
      sheet.cells(rowsNum, 2) = "字段名称"
      sheet.cells(rowsNum, 3) = "字段类型"
      sheet.cells(rowsNum, 4) = "是否主键"
      sheet.cells(rowsNum, 5) = "默认值"
      sheet.cells(rowsNum, 6) = "是否可空"

      for each col in tab.columns
      rowsNum = rowsNum + 1
      colsNum = colsNum + 1
      sheet.cells(rowsNum, 1) = col.name
      sheet.cells(rowsNum, 2) = col.code
      sheet.cells(rowsNum, 3) = ""
      sheet.cells(rowsNum, 4) = ""
      sheet.cells(rowsNum, 5) = ""
      sheet.cells(rowsNum, 6) = ""
	  sheet.cells(rowsNum, 7) = col.name
      next
      sheet.Range(sheet.cells(rowsNum-colsNum+1,1),sheet.cells(rowsNum,7)).Borders.LineStyle = "2"      
 
      Output "FullDescription: "       + tab.Name
   End If
End Sub

只需要Crtl+Shift+X调出命令窗口，执行这段脚本就可以把PowerDesigner的表结构导出为约定好格式的Excel文件啦。

导出的Excel长这样：
