【转】使用Mysql-connector-c++插入数据时乱码解决

// MySqlTest.cpp : 定义控制台应用程序的入口点。
//

#include <iostream>
using namespace std;

//MySQL Connector C++ 1.0.5,接口跟Oracle的OCCI长的很像(跟JDBC也像),Oracle-MySql官方网站可下载
//D:\Program Files\MySQL\MySQL Connector C++ 1.0.5\include
//D:\Program Files\MySQL\MySQL Connector C++ 1.0.5\lib\opt

#include <mysql_connection.h>
#include <cppconn/statement.h>
#include <cppconn/exception.h>
using namespace sql;
using namespace sql::mysql;

#pragma comment(lib,"mysqlcppconn.lib")

int main(int argc, char* argv[])
{
try
{
//数据库连接
MySQL_Connection MySqlConn("localhost","root","006355");

//选择数据库(模式)
MySqlConn.setSchema("test");

Statement *pStatement = MySqlConn.createStatement();

//在Mysql数据库中，我设置的编码是GB2312,但是这里读出的仍是UTF-8编码的字符
//所以需这句来解决乱码问题

//执行无记录集返回的语句
pStatement->execute("set names gb2312");

//执行有记录集返回的语句
//注意反引号 "`",呵呵
ResultSet* pRs=pStatement->executeQuery("Select * from `Users`");

while (pRs->next())
{
cout<<pRs->getInt("id")<<endl;

string sChineseText=pRs->getString(2);
cout<<sChineseText<<":";

//输出汉字的编码
//D5 C5 C8 FD               张三  ANSI/OEM936：GBK/GB2312
//E5 BC A0 E4 B8 89    张三  UTF8
for (size_t i=0;i<sChineseText.length();i++)
{
printf("%02X ",(unsigned char)sChineseText[i]);
}
cout<<endl;

cout<<pRs->getString("password")<<endl<<endl;
}

pRs->close();
pStatement->close();
MySqlConn.close();
}
catch (SQLException& ex)
{
cout<<"Error:"<<ex.what()<<endl;
}

return 0;
}

可惜的是：
22.5.12.2: Which MySQL Server version(s) is MySQL Connector/C++ compatible with?
MySQL Connector/C++ fully supports MySQL Server version 5.1 and later.[/align]
使用低版本MySQL服务器的话，还需MySQL C API。
