从Excel中设计好表结构导入到PowerDesiginer。
1、编写Excel模板(模板和后面的脚本需要一致)

2、打开PowerDesigner,创建物理模型(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 "E:\Temp\1.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
dim abc
on error Resume Next
'--------------------------------
'下面是读取excel,添加表实体属性
'--------------------------------
For rwIndex = 1 To 300 step 1 '指定要遍历的Excel行标 由于第2行是表头,从第1行开始,看你这个表设计多少行
With x1.Workbooks(1).Worksheets("Sheet1")'需要循环的sheet名称
'If .Cells(rwIndex, 1).Value = "" Then
'Exit For
' End If
'If .Cells(rwIndex,1).Value = "表" Then 'And .Cells(rwIndex,2).Value <> "" And .Cells(rwIndex,3).Value <> "" Then'Excel中表头的1列是表名,2表名中文,3是表注释
If rwIndex = 1 then '第一行取表信息
set table = mdl.Tables.CreateNew '创建一个表实体
table.Code = .Cells(rwIndex,2).Value'从excel中取得表名称和编码
table.Name = .Cells(rwIndex,3).Value'
table.Comment = .Cells(rwIndex,4).Value '指定列说明
'count = count + 1
Continue
End If
If .Cells(rwIndex,1).Value = "" or .Cells(rwIndex,1).Value = "字段" Then '第1列为空的都可以忽略
Continue '这里忽略空行和表名行、表头行
Else
set col =table.Columns.CreateNew '创建一列/字段
col.Code = .Cells(rwIndex, 1).Value '指定列code
col.DataType = .Cells(rwIndex, 2).Value '指定列数据类型
If.Cells(rwIndex, 3).Value = "Y" Then'指定主键
col.Primary =true
End If
If.Cells(rwIndex, 4).Value = "N" Then'指定列是否可空 true 为不可空
col.Mandatory =true
End If
col.Name = .Cells(rwIndex, 5).Value '指定列name
col.Comment = .Cells(rwIndex, 6).Value '指定列说明
count = count + 1
End If
'If (.Cells(rwIndex,1).Value = "" And .Cells(rwIndex,2).Value = "" And .Cells(rwIndex,3).Value = "") Or (.Cells(rwIndex,1).Value <> "" And .Cells(rwIndex,2).Value = "" And .Cells(rwIndex,3).Value <> "")Then
End With
Next
MsgBox "生成数据表结构共计 " + CStr(count), vbOK + vbInformation, "表"
Exit Sub
End sub
4、运行脚本
5、检查表进行微调整
