使用ADO通过ODBC连接MYSQL >MFC工程
1.配置名字为myodbc的数据源
2.在stdafx.h中加上
#import "c:\program files\common files\system\ado\msado15.dll" no_namespace rename ("EOF", "adoEOF")
3.在程序初始化的方法中加上
AfxEnableControlContainer();
// 初始化COM,创建ADO连接等操作
AfxOleInit();
4.在合适的地方加上
public:_ConnectionPtr m_pConnection;
5.连接mysql
m_pConnection.CreateInstance(__uuidof(Connection));
// 在ADO操作中建议语句中要常用try...catch()来捕获错误信息,因为它有时会经常出现一些想不到的错误。
try
{
// 打开本地Access库student.mdb
m_pConnection->Open("myodbc","","",adModeUnknown);
}
catch(_com_error e)
{
AfxMessageBox(_T("数据库连接失败,!"));
return FALSE;
}

由于能直接在MYSQL数据库里添加中文数据,并且能正常显示,说明我的表都使用了正确的字符编码,经过查看后,确认了,我全部的表以及字段都使用了UTF-8的编码,但是为什么程序添加的中文数据就不行呢?
其实,原因在于MYSQL服务器使用的默认编码,以及数据库的默认编码,很多人已经很小心的在建立表时关注表的字符编码,却忽略了数据库 ......
了解了一些最基本的操作命令后，我们再来学习如何创建一个数据库和数据库表。
1、使用SHOW语句找出在服务器上当前存在什么数据库：

For our four-node, four-host MySQL Cluster, it is necessary to
write four configuration files, one per node host.
Each data node or SQL node requires a
my.cnf
file that provides two pieces of

Starting the cluster is not very difficult after it has been configured. Each cluster node process must be started separately, and on the host where it resides. The management node should be started first, followed by the data nodes, and then finally by any SQL nodes:
On the management host, issu ......
To shut down the cluster, enter the following command in a shell
on the machine hosting the management node:
shell> ndb_mgm -e shutdown
The -e
option here is used to pass a command to
the ndb_mgm
client from the shell. (See
Section 4.23, “ ......
