//我修改之，能正常运行，测试环境为mysql5.0,xp
//关键是设置对字符集，设置gbk,gb2312测试通过,utf8测试未通过
//在运行程序前先建立数据库jj,注意下面几个参数(修改为你自己的)
复制代码 代码如下:
// char *host = "localhost";
// char *user = "root";
// char *pass = "674800";
// char *db = "jj";
#include <windows.h>
#include <iostream>
#include <mysql.h>
#include <stdio.h>
#include <string.h>
using namespace std;
#pragma comment(lib,"libmysql.lib")
int connDB();
int create_table();
int insert_table();
int select_table();
int disconnDB();
MYSQL *mysql;
MYSQL_RES *res;
MYSQL_FIELD * fd;
MYSQL_ROW row;
char szSqlText[500]="";
int i;
int main()
{
connDB();
// create_table();
insert_table();
select_table();
disconnDB();
return 0;
}
///////////////子函数
int connDB()//连接数据库

char *pass = "674800";
char *db = "jj";
mysql = mysql_init((MYSQL*) 0);
mysql_real_connect( mysql, host, user, pass, db,3306, NULL, 0 ) ; //链接到服务器
mysql_set_character_set(mysql,"gb2312"); //设置字符集
cout<<"conn OK!"<<endl;
return 0;
}
//关闭数据库
int disconnDB()
{
mysql_close( mysql ) ;
cout<<"disconn OK!"<<endl;
return 0 ;
}
//创建表
int create_table()
{
mysql_set_character_set(mysql,"gb2312");
sprintf(szSqlText, \

if(mysql_query( mysql, szSqlText))

return 0;
}
int insert_table()
{

sprintf(szSqlText,

values('2000-3-10 21:01:30',\

'清风寒剑',\

for ( i = 0 ; fd = mysql_fetch_field( res ) ; i++ )

我机器上的运行结果：
