用DELPH写的DAO访问模块.有连接池.应用了各种模块,把数据库操作

unit uMssqlDaoFactory;

interface

uses
  uDaoFactory, DB, uMemberDAO, uMssqlMemberDAO, ADODB;

type
//==============================================================================
// Mssql数据库DAO工厂类

  TMssqlDaoFactory = class(TDaoFactory)
  private

  public
    constructor Create;
    destructor Destroy; override;
    function getMemberDAO : IMemberDAO; override;
    //function createConnection : TCustomConnection; reintroduce; overload;
  end;

function TMssqlDaoFactory.getMemberDAO: IMemberDAO;
begin
  result := TMssqlMemberDAO.create(fConn as Tadoconnection);
end;
