使用ODBC连接SQL Server数据库

建立ODBC数据库时要设置默认数据库，我这设置的默认数据库是mrxt

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, DB, DBTables, Grids, DBGrids, StdCtrls;

type
  TForm1 = class(TForm)
    DBGrid1: TDBGrid;
    Query1: TQuery;
    DataSource1: TDataSource;
    Label1: TLabel;
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
  with Query1 do
  begin
    close;
    SQL.clear;
    SQL.Add('select * from cj');
    Open;
  end;
end;

end.
