先去那個(gè)網(wǎng)站下載個(gè)文件 7MB左右

VS 2017創(chuàng)建一個(gè)工程，工程名字隨便起，最好不要中文

從mysql 官網(wǎng)下載的文件解壓，把lib文件夾和include文件夾復(fù)制到項(xiàng)目工程文件里面，如圖

然后選中項(xiàng)目右擊一下，屬性設(shè)置依賴項(xiàng)

到mysql安裝的文件夾找到兩個(gè)dll文件復(fù)制到工程文件

添加一個(gè)頭文件 c_mysql.h

#pragma once #pragma comment(lib,"libmysql.lib") #ifndef C_MYSQL_H_ #define C_MYSQL_H_ #include <stdio.h> #include <stdlib.h> #include <winsock2.h> #include <windows.h> #include <mysql.h> void execute_sql(const char* sql);#endif

點(diǎn)CPP 文件代碼

#include "c_mysql.h" #define HOST "localhost" #define USERNAME "root" #define PASSWORD "root" #define DATABASE "test" int main() {const char *sql = "select * from tt_user";execute_sql(sql);return 0; }void execute_sql(const char* sql) {MYSQL connection;MYSQL_RES *result_pointer;MYSQL_ROW result_row;int result, row, column, i, j;mysql_init(&connection);if (NULL == mysql_real_connect(&connection, HOST, USERNAME, PASSWORD, DATABASE, 3306, NULL, CLIENT_FOUND_ROWS)){printf("Error:connection failed!\n");return;}mysql_query(&connection, "set names gbk");result = mysql_query(&connection, sql);if (result){printf("Error:query failed!\n");mysql_close(&connection);return;}result_pointer = mysql_store_result(&connection);if (result_pointer){row = mysql_num_rows(result_pointer);for (i = 1; i < row + 1; i++){result_row = mysql_fetch_row(result_pointer);printf("|%s|%s||%s|%s|\n", result_row[0], result_row[1], result_row[2], result_row[3]);}}mysql_close(&connection);system("pause"); }

sql建表語(yǔ)句

/* SQLyog Ultimate v10.00 Beta1 MySQL - 5.7.18-log ********************************************************************* */ /*!40101 SET NAMES utf8 */;create table `tt_user` (`id` int ,`name` varchar ,`age` int ,`address` varchar ); insert into `tt_user` (`id`, `name`, `age`, `address`) values('1','大軍','26','上海市'); insert into `tt_user` (`id`, `name`, `age`, `address`) values('2','小楊','24','云南'); insert into `tt_user` (`id`, `name`, `age`, `address`) values('3','趙劉','27','陜西'); insert into `tt_user` (`id`, `name`, `age`, `address`) values('4','李四','23','安徽'); insert into `tt_user` (`id`, `name`, `age`, `address`) values('5','老劉','30','安徽安慶'); insert into `tt_user` (`id`, `name`, `age`, `address`) values('6','王二','22','北京市'); insert into `tt_user` (`id`, `name`, `age`, `address`) values('7','123','213','213');
