本文實例講述了C語言實現訪問及查詢MySQL數據庫的方法。分享給大家供大家參考,具體如下:
1、添加頭文件路徑(MySQL安裝路徑中的include路徑)
2、添加庫文件(直接從MySQL安裝路徑中copy libmysql.lib即可)
3、編程操作數據庫
代碼
// AccessToMySQL.cpp : 定義控制臺應用程序的入口點。//#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;}
運行效果:
希望本文所述對大家C語言程序設計有所幫助。
