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
代码
// AccessToMySQL.cpp : 定义控制台应用程序的入口点。
//
#include "stdafx.h"
#include
#include
#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。
