C++对Mysql数据库的访问查询（基于Mysql5.0的API，vs2010中操作

右击项目名称-属性，配置引用Mysql数据库的库目录，见图： 添加附加包目录为C:\Program Files\MySQL\MySQL Server 5.0\include 拷贝libmySQL.dll(C:\Program Files\MySQL\MySQL Server 5.0\bin)和libmysql.lib（C:\Program Files\MySQL\MySQL Server 5.0\lib

拷贝libmySQL.dll(C:\Program Files\MySQL\MySQL Server 5.0\bin)和libmysql.lib（C:\Program Files\MySQL\MySQL Server 5.0\lib\opt）到运行目录下，如调试时放在Debug下

然后代码如下

#include "windows.h"
#include "winsock.h"
#include "stdio.h"
#include "mysql.h"
#pragma comment(lib,"libmySQL.lib")
#include <iostream>
using namespace std;
int main()
{

	char dbuser[30]="root";
	char dbpasswd[30]="password";
	char dbip[30]="localhost";
	char dbname[50]="temperature";
	MYSQL *con=mysql_init((MYSQL *)0);
	
	if (con!=NULL&&mysql_real_connect(con,dbip,dbuser,dbpasswd,dbname,3306,NULL,0))
	{
		printf("SUCCESSFULLY.");
		mysql_query(con,"select * from temperature");
		MYSQL_RES *result=mysql_store_result(con);
		unsigned int fieldcount=mysql_num_fields(result);
		cout<<fieldcount<<endl;
		MYSQL_FIELD *field=NULL;
		MYSQL_ROW row=NULL;
		while(row=mysql_fetch_row(result))
		{
			for (unsigned int i=0;i<fieldcount;i++)
			{
				field=mysql_fetch_field_direct(result,i);
				cout<<field->name<<":"<<row[i]<<"  ";
			}
			cout<<endl;
		}
		mysql_free_result(result);
		mysql_close(con);
		mysql_server_end();
		mysql_library_end();
	}
	else
	{
		printf("ERROR.");
	}
	while(1);
}
