本文实例讲述了C语言实现访问及查询MySQL数据库的方法。分享给大家供大家参考,具体如下:
1、添加头文件路径(MySQL安装路径中的include路径)
2、添加库文件(直接从MySQL安装路径中copy libmysql.lib即可)
3、编程操作数据库

// AccessToMySQL.cpp : 定义控制台应用程序的入口点。
//
#include "stdafx.h"
#include <Windows.h>
#include <mysql.h>
#pragma comment(lib,"libmysql.lib")
MYSQL mysql;
MYSQL_RES* result;
MYSQL_ROW row;
int main( void )
{
//init the mysql parameter
mysql_init(&mysql);
//connect the database
if (!mysql_real_connect(&mysql, "127.0.0.1" , "root" , "111" , "mytest" ,3306,NULL,0))
{
printf (mysql_error(&mysql));
printf ( "\nCannot access to the database!!!\n" );
system ( "pause" );
exit (-1);
}
//construct the query SQL statements
char * sql= "select * from student where name='" ;
char dest[100]={ "" };
strcat (dest,sql);
printf ( "Please enter the student name:" );
char name[10]={ "" };
gets (name);
strcat (dest,name);
strcat (dest, "'" );
//excute the SQL statements
if (mysql_query(&mysql,dest))
{
printf ( "Cannot access the database with excuting \"%s\"." ,dest);
system ( "pause" );
exit (-1);
}
//deal with the result
result=mysql_store_result(&mysql);
if (mysql_num_rows(result))
{
while ((row=mysql_fetch_row(result)))
{
printf ( "%s\t%s\t%s\n" ,row[0],row[1],row[2]);
}
}
//release the resource
mysql_free_result(result);
mysql_close(&mysql);
system ( "pause" );
return 0;
}

运行效果:
希望本文所述对大家C语言程序设计有所帮助。
