前提

要做数据源的整理,需要将Mysql数据库表的结构导出到Excel表里面做文档记录;

第一个Sheet是所有表格的列表,其他的Sheet是每一个表格的详细字段以及注释说明.

打开PowerDesigner的数据库结构导出Excel脚本页面

选择好连接的数据库以后,ctrl+shift+x 弹出执行脚本界面，输入如下代码就会生成 Excel

Option Explicit   
   Dim rowsNum
   Dim splitTabName
   rowsNum = 0

  MsgBox "The current model is not an PDM model."

      '设置背景颜色  
      sheet.Range(sheet.cells(1, 1),sheet.cells(1, 3)).Interior.ColorIndex = "19"  
  
      rowsNum = rowsNum + 1  
      sheet.cells(rowsNum+1, 1) = rowsNum   
      sheet.cells(rowsNum+1, 2) = tab.code  
      sheet.cells(rowsNum+1, 3) = tab.comment  
      '设置边框  
      sheet.Range(sheet.cells(rowsNum+1,1),sheet.cells(rowsNum+1,3)).Borders.LineStyle = "2"  
  
      '增加Sheet  
      BOOK.Sheets.Add , BOOK.Sheets(BOOK.Sheets.count)
	  '截取右边开始的31个字符
	  splitTabName = Right(tab.code, 31)
      BOOK.Sheets(rowsNum+1).Name = Right(tab.code, 31)   
  
      Dim shtn  
      Set shtn = EXCEL.workbooks(1).sheets(splitTabName)  
      '设置列宽和换行  
       shtn.Columns(1).ColumnWidth = 20     
       shtn.Columns(2).ColumnWidth = 20     
       shtn.Columns(3).ColumnWidth = 20  
       shtn.Columns(4).ColumnWidth = 20     
  
       shtn.Columns(1).WrapText =true   
       shtn.Columns(2).WrapText =true   
       shtn.Columns(3).WrapText =true  
       shtn.Columns(4).WrapText =true  
  
       '设置列标题  
       shtn.cells(1, 1) = "字段中文名"   
       shtn.cells(1, 2) = "字段名"  
       shtn.cells(1, 3) = "字段类型"
       shtn.cells(1, 4) = "注释"  
       '设置边框   
       shtn.Range(shtn.cells(1, 1),shtn.cells(1, 2)).Borders.LineStyle = "1"  
       shtn.Range(shtn.cells(1, 3),shtn.cells(1, 4)).Borders.LineStyle = "1"  
       '设置背景颜色  
       shtn.Range(shtn.cells(1, 1),shtn.cells(1, 2)).Interior.ColorIndex = "19"  
       shtn.Range(shtn.cells(1, 3),shtn.cells(1, 4)).Interior.ColorIndex = "19"  
  
      Dim col ' running column   
      Dim colsNum  
      Dim rNum   
      colsNum = 0  
      rNum = 0   
            for each col in tab.columns   
              rNum = rNum + 1   
              colsNum = colsNum + 1   
  
            shtn.cells(rNum+1, 1) = col.name   
            shtn.cells(rNum+1, 2) = col.code   
            shtn.cells(rNum+1, 3) = col.datatype
	    shtn.cells(rNum+1, 4) = col.comment			
            next   
            shtn.Range(shtn.cells(rNum-colsNum+2,1),shtn.cells(rNum+1,3)).Borders.LineStyle = "2"           
            rNum = rNum + 1   
  
            Output "FullDescription: "       + tab.Name  
  
   End If     
End Sub

核心代码段是:

      sheet.cells(1, 1) = "序号"   
      sheet.cells(1, 2) = "表名"  
      sheet.cells(1, 3) = "表含义"  
      '设置边框   
      sheet.Range(sheet.cells(1, 1),sheet.cells(1, 3)).Borders.LineStyle = "1"  
      '设置背景颜色  
      sheet.Range(sheet.cells(1, 1),sheet.cells(1, 3)).Interior.ColorIndex = "19"  
  
      rowsNum = rowsNum + 1  
      sheet.cells(rowsNum+1, 1) = rowsNum   
      sheet.cells(rowsNum+1, 2) = tab.code  
      sheet.cells(rowsNum+1, 3) = tab.comment

这是设置第一个Sheet的每一列都是什么内容;

'设置列宽和换行  
       shtn.Columns(1).ColumnWidth = 20     
       shtn.Columns(2).ColumnWidth = 20     
       shtn.Columns(3).ColumnWidth = 20  
       shtn.Columns(4).ColumnWidth = 20     
  
       shtn.Columns(1).WrapText =true   
       shtn.Columns(2).WrapText =true   
       shtn.Columns(3).WrapText =true  
       shtn.Columns(4).WrapText =true  
  
       '设置列标题  
       shtn.cells(1, 1) = "字段中文名"   
       shtn.cells(1, 2) = "字段名"  
       shtn.cells(1, 3) = "字段类型"
       shtn.cells(1, 4) = "注释"  
       '设置边框   
       shtn.Range(shtn.cells(1, 1),shtn.cells(1, 2)).Borders.LineStyle = "1"  
       shtn.Range(shtn.cells(1, 3),shtn.cells(1, 4)).Borders.LineStyle = "1"  
       '设置背景颜色  
       shtn.Range(shtn.cells(1, 1),shtn.cells(1, 2)).Interior.ColorIndex = "19"  
       shtn.Range(shtn.cells(1, 3),shtn.cells(1, 4)).Interior.ColorIndex = "19"

这是设置数据库导出的内容,我的这里只是设置了字段中文名,字段名,字段类型和注释,如果有其他的要求,可自行设置

'增加Sheet  
      BOOK.Sheets.Add , BOOK.Sheets(BOOK.Sheets.count)
	    '截取右边开始的31个字符
	    splitTabName = Right(tab.code, 31)
      BOOK.Sheets(rowsNum+1).Name = Right(tab.code, 31)

这一段代码是由于Excel中每一个Sheet的名称长度限制为31个字符,在这里我做了一个截取,从每一个数据表名称的右边开始截取31个字符.
