'这是个简单的单机型数据库入门代码,可以从中学习数据库操作的初级知识
'这里面的添加删除表和添加删除字段在添加记录和删除记录这个版块中没有实际作用
'只是作为演示的一个用途,一般情况下先就设定好表和字段了,不需要实时开通表和记录功能的
'在数据库中进行SQL操作，看子程序list里面有打开数据库时执行SQL的语句
Public Function Add() '公用的添加数据子程序
'程序在ACCESS2003 MDB下通过,并在ACCESS2000中建立了MDB数据库文件
'声明变量
Dim DB As Database '声明DB变量用于数据库
Dim RS As Recordset '声明RS变量用于记录集
Dim WS As Workspace '声明WS变量用于工作空间
'这儿设置用于定义工作空间
Set WS = DBEngine.Workspaces(0)
'这儿设置数据库连接语句,指向MDB文件
Set DB = WS.OpenDatabase(App.Path & "\dbtut.mdb")
'这开是打开数据库MDB,并打开里面的表Email
Set RS = DB.OpenRecordset("email", dbOpenTable)
'添加一个空的新记录
RS.AddNew
'把text1.text的内容写入name
'把text2.text的内容写入e-mail

RS("E-Mail") = Text2.Text
'更新update,也就是添加记录进去
RS.Update
'关闭数据库
DB.Close
