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。
