你的位置： 鸟儿网络 > 菜鸟编程 > delphi连接access数据库示例 很简单的一组代码，假设我们有一个名字叫db1.mdb的数据库，里面有一个叫做table1的表。然后代码如下：

[code=delphi]

unit Unit1;

interface

uses

Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

Dialogs, Grids, DBGrids, StdCtrls, DB, ADODB;

type

TForm1 = class(TForm)

conn: TADOConnection;

Button1: TButton;

DBGrid1: TDBGrid;

ADOQuery1: TADOQuery;

DataSource1: TDataSource;

procedure FormCreate(Sender: TObject);

procedure Button1Click(Sender: TObject);

private

{ Private declarations }

public

{ Public declarations }

end;

var

Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);

begin

try

self.conn.Close;

self.conn.ConnectionString:='Provider=Microsoft.Jet.OLEDB.4.0;Data Source='+sysutils.ExtractFilePath(application.ExeName)+

'db1.mdb;Persist Security Info=False';

self.conn.Connected:=true;

except on e:exception do

application.MessageBox(Pchar(e.Message),'提示',32);

end;

self.ADOQuery1.Active:=true;

end;

procedure TForm1.Button1Click(Sender: TObject);

begin

self.ADOQuery1.Active:=not self.ADOQuery1.Active;

end;

end.[/code]

窗体代码:
