第一步：建立数据库

假设有一个sql文件

mysql>use dbname;                   //创建一个数据库名为dbname的数据库(空数据库)

mysql>set names utf8;              //编码，mysql>source D:/dbname.sql;  //导入一个数据库源文件创建数据库内容

我做的工程数据库名称是db_grain

第二步创建数据源

三、搭建数据源。

本项目中是用的是odbc(驱动)+mysql的数据源

1、安装相应的mysql-connector(分32，64位)。

我装的是mysql-connector-odbc-5.1.5-win32.msi驱动。

2、控制面板è管理工具(或{性能与…..})è数据源(odbc)è添加è你相应的odbc驱动。

(我的是5.1)è完成

3.完成后会跳出下面对话框。Name可以自己填，软件项目中会用到下面你填的内容

database在填写server,port,user,password后直接下拉得到,如果没有则前面的填写错误

4.

配置ado cpp文件

1、在项目中导入下面两个文件到相应包下面。

5.修改ado.cpp文件的OnInitADOConn()//不同驱的数据源只要改onInitADOConn()中的两个值(bstr_t strConnect,m_pConnection->Open)就行了，其他不要改

void ADO::OnInitADOConn()

{

::CoInitialize(NULL);

try

{

m_pConnection.CreateInstance("ADODB.Connection"); //这里不用改

_bstr_t strConnect="DRIVER={MySQL ODBC 5.1 Driver};//这里改成你的驱动名称(假如你的是access数据驱动改成你的access驱动如Microsoft Access Driver (*.mdb))

Server=localhost;

/*

Persist Security Info ----是否保存安全信息User ID-------------------用户名PassWord------------------密码Initial Catalog-----------数据库的名称或者数据库ip或者目录Data Source---------------数据源

*/

PassWord=123456;

Persist Security Info=False;

User ID=root;

Data Source=autoresour";

m_pConnection->Open(strConnect,"","",adModeUnknown); //

/* Open (

const _variant_t & Source,

const _variant_t & ActiveConnection,

enum CursorTypeEnum CursorType,//””

enum LockTypeEnum LockType,//一般为””

long Options ); }*/ //一般是 adModeUnknown

catch(_com_error e)

{

AfxMessageBox(e.Description()); //

}

}

以我工程的数据源名称为"autoresour"为例

1.adAffectCurrent Deletes only the current record 仅删除当前记录

2.adAffectGroup Deletes only records that satisfy the Filter setting (Filter must be set to a FilterGroupEnum value or an array of Bookmarks)

对满足当前 Filter 属性设置的记录取消挂起更新。使用该选项时，必须将Filter属性设置为合法的FilterGroupEnum常量之一或设置成一个书签数组
