C语言连接mysql数据库实战

[code]#include <stdlib.h>
#include <stdio.h>
#include "/usr/local/mysql/include/mysql/mysql.h"#mysql的接口函数都在mysql.h中有定义，所以很多接口函数可以使用

int main()
{

    MYSQL mysql_link;
    int ret;
    MYSQL_RES *result;
    MYSQL_ROW sql_row;
    MYSQL_FIELD *fd;
    char sql_str[50] = "SELECT * FROM t2";
    mysql_init(&mysql_link);
    if(mysql_real_connect(&mysql_link,"127.0.0.1","root","123456","test",3306,NULL,0))
    {
        printf("connect success\n");
        ret = mysql_query(&mysql_link,sql_str);
        if(ret == 0)
        {
            result = mysql_store_result(&mysql_link);
            if(result)
            {
                printf("\n");
                while((fd=mysql_fetch_field(result)) !=NULL )
                {
                    printf("%s\t",fd->name);
                }
                printf("\n");
                while(sql_row=mysql_fetch_row(result))
                {
                    printf("%s\t%s\n",sql_row[0],sql_row[1]);
                }
            }
        }
    }
    else
    {
        printf("connect faile\n");
    }
    mysql_free_result(result);
    mysql_close(&mysql_link);
    return 0;
}
