powerdesigner-从excel导入table模型

Posted 2020-07-16 y酒味i

近在使用pd过程中，遇到一个问题，就是类的字段，方法，类型在excel中整理好了，想导入到pd直接生成类图。网上有很多生成实体表的方法，于是自己模仿写了一个生成类图的，在pd中的工具--扩展--脚本，或者直接快捷键shift + ctrl + X 打开脚本窗口，执行以下代码即可

1.编写EXCEL:

 

2.打开PowerDesigner，创建物理模型(Physical Data Model)-因不同的pd模型在使用时 是不通的编码-所以这里测试使用Physical Data Model

 3.在PowerDesigner菜单栏中，依次点击“Tools ->Excute Commands->Edit/Run Script..”

 

 Option Explicit   
Dim mdl \' the current model 
Set mdl = ActiveModel 
If (mdl Is Nothing) Then   
  MsgBox "There is no Active Model" 
End If 
  
Dim HaveExcel 
Dim RQ  
RQ = vbYes \'MsgBox("Is Excel Installed on your machine ?", vbYesNo + vbInformation, "Confirmation") 
If RQ = vbYes Then  
   HaveExcel = True  
\' Open & Create Excel Document 
 Dim x1 \'  
  Set x1 = CreateObject("Excel.Application")
  x1.Workbooks.Open "C:\\Users\\huage\\Desktop\\test\\11.xlsx" 
  x1.Workbooks(1).Worksheets("Sheet1").Activate 
Else
   HaveExcel = False 
End If 
  
a x1, mdl 
  
sub a(x1,mdl) 
dim rwIndex 
dim tableName 
dim colname 
dim table 
dim col 
dim count 
  
\'on error Resume Next 
For rwIndex = 1 To 1000 step 1   
    With x1.Workbooks(1).Worksheets("Sheet1")
  \'MsgBox "生成数据表结构共计1 ="+CStr(.Cells(2,2).Value ), vbOK + vbInformation, "表" 
   If .Cells(rwIndex, 1).Value = "" Then 
       Exit For 
   End If  
  If .Cells(rwIndex, 3).Value = "" Then 
    set table = mdl.Tables.CreateNew 
        table.Name = .Cells(rwIndex , 1).Value 
        table.Code = .Cells(rwIndex , 2).Value 
        count = count + 1  
   Else   
    colName = .Cells(rwIndex, 1).Value 
    set col = table.Columns.CreateNew  
   \'MsgBox .Cells(rwIndex, 1).Value, vbOK + vbInformation, "列" 
    col.Name = .Cells(rwIndex, 1).Value 
    \'MsgBox col.Name, vbOK + vbInformation, "列"
     col.Code = .Cells(rwIndex, 2).Value 
    col.Comment = .Cells(rwIndex,1).Value  
    col.DataType = .Cells(rwIndex, 3).Value 
   End If 
  End With 
Next 
  
MsgBox "生成数据表结构共计" + CStr(count), vbOK + vbInformation, "表" 
 
Exit Sub 
End sub 

 

第二种-有解析版（但有写小bug）

\'开始
Option Explicit

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

Dim HaveExcel
Dim RQ
RQ = vbYes \'MsgBox("Is  Excel Installed on your machine ?", vbYesNo + vbInformation, "Confirmation")
If RQ = vbYes Then
HaveExcel = True
\' Open & Create  Excel Document
Dim x1 \'
Set x1 = CreateObject("Excel.Application")
x1.Workbooks.Open "C:\\Users\\huage\\Desktop\\test\\11.xlsx" \'指定 excel文档路径
x1.Workbooks(1).Worksheets("Sheet1").Activate \'指定要打开的sheet名称
Else
HaveExcel = False
End If

a x1, mdl

sub a(x1, mdl)
dim rwIndex 
dim tableName
dim colname
dim table
dim col
dim count

on error Resume Next

set table = mdl.Tables.CreateNew \'创建一个 表实体
table.Name = "Sheet1" \'指定 表名，如果在 Excel文档里有，也可以 .Cells(rwIndex, 3).Value 这样指定
table.Code = "Sheet1" \'指定 表名
count = count + 1

For rwIndex = 1 To 1000 \'指定要遍历的 Excel行标 由于第1行是 表头， 从第2行开始
With x1.Workbooks(1).Worksheets("Sheet1")
If .Cells(rwIndex, 1).Value = "" Then
Exit For
End If

set col = table.Columns.CreateNew \'创建一列/字段
\'MsgBox .Cells(rwIndex, 1).Value, vbOK + vbInformation, "列"
If .Cells(rwIndex, 3).Value = "" Then
col.Name = .Cells(rwIndex, 1).Value \'指定列名
Else 
col.Name = .Cells(rwIndex, 3).Value
End If
\'MsgBox col.Name, vbOK + vbInformation, "列"
col.Code = .Cells(rwIndex, 1).Value \'指定列名
col.DataType = .Cells(rwIndex, 2).Value \'指定列数据类型
col.Comment = .Cells(rwIndex, 5).Value \'指定列说明
If .Cells(rwIndex, 4).Value = "否" Then
col.Mandatory = true \'指定列是否可空 true 为不可空 
End If
If rwIndex = 2 Then
col.Primary = true \'指定主键
End If
End With
Next
MsgBox "生成数据 表结构共计 " + CStr(count), vbOK + vbInformation, " 表"

Exit Sub
End sub

 

5.测试
5.1用的EXCEL：C:\\Users\\huage\\Desktop\\test\\11.xlsx注意这个路径要与脚本中的路径一致

5.2运行脚本
5.3检查导入效果
