PowerDesigner支持VBScript脚本,帮助生成数据库模型中的对象。具体功能入口在菜单Tools-->Execute Commands-->Edit/Run Script,下面是我写的一个快速生成数据库表的脚本,在我的项目实践中,因为有太多的表要从需求调研报告中提取出来,在PD中一个字段一个字段的输入实在太费劲了,就想了这个办法偷赖。代码如下:

Option Explicit

'-----------------------------------------------------------------------------

' Initialization

'-----------------------------------------------------------------------------

Dim system, file

Set system = CreateObject("Scripting.FileSystemObject")

' Open mode constants...

Dim ForReading, ForWriting, ForAppending

ForReading = 1 ' Open a file for reading only. You can't write to this file.

ForWriting = 2 ' Open a file for writing.

ForAppending = 8 ' Open a file and write to the end of the file.

'-----------------------------------------------------------------------------

' Main function

'-----------------------------------------------------------------------------

Set file = system.OpenTextFile("D:\table.txt", ForReading)

Dim noLine

Dim Tab 'table

ValidationMode = True

Dim mdl ' the current model

Dim Col

dim dm, dmstr

Dim SSS

Dim isNewTable

' get the current active model

Set mdl = ActiveModel

For each dm in mdl.domains

If Not dm.isShortcut Then

If dm.code = "dm_pk" Then

Exit For

End If

End If

Next

For each dmstr in mdl.domains

If Not dmstr.isShortcut Then

If dmstr.code = "dm_string" Then

Exit For

End If

End If

Next

set Tab = mdl.Tables.CreateNew

set Col=tab.Columns.CreateNew

Col.name = "ID"

Col.Code = "ID"

col.domain=dm

Col.Primary = True

isNewTable = True

Do While file.AtEndOfStream <> True

SSS = file.ReadLine

if isNewTable = True then

if SSS <> "" then

isNewTable = False

tab.name = SSS

end if

elseif SSS = "" then

set Tab = mdl.Tables.CreateNew

set Col=tab.Columns.CreateNew

Col.name = "ID"

Col.Code = "ID"

col.domain=dm

Col.Primary = True

isNewTable = True

else

set Col=tab.Columns.CreateNew

Col.name = SSS

col.domain=dmstr

end if

Loop

file.Close

这样我只要将所需的实段名和表名放在文本文件中,不同的表以空行分开,就可以自动增加表了。

不过生成的字段名都是Column1...ColumnN,然后再一个一个改吧。
