拷贝C:/Program Files/MySQL/MySQL Server 8.0/lib下文件到可执行程序下

3.测试代码

#include <iostream>

#include"mysql.h"

using namespace std;

int main()
{
    cout << "mysq version:" <<mysql_get_client_info()<< endl;

    // 初始化MySQL连接对象
    MYSQL *conn = mysql_init(NULL);
    if (conn == NULL) {
        std::cerr << "mysql_init() failed" << std::endl;
        return 1;
    }
    // 连接到MySQL数据库
    if (mysql_real_connect(conn, "localhost", "root", "123456", "db01", 0, NULL, 0)== NULL) {
        std::cerr << "mysql_real_connect() failed: " << mysql_error(conn) << std::endl;
        mysql_close(conn);
        return 1;
    }
    // 执行查询语句
    if (mysql_query(conn, "SELECT * FROM tb_user")) {
        std::cerr << "mysql_query() failed: " << mysql_error(conn) << std::endl;
        mysql_close(conn);
        return 1;
    }
    // 获取结果集
    MYSQL_RES *result = mysql_store_result(conn);
    if (result == NULL) {
        std::cerr << "mysql_store_result() failed: " << mysql_error(conn) << std::endl;
        mysql_close(conn);
        return 1;
    }
    // 获取结果集中的行数和列数
    int num_fields = mysql_num_fields(result);
    MYSQL_ROW row;
    while ((row = mysql_fetch_row(result))) {\

        for (int i = 0; i < num_fields; i++) {
            std::cout << row[i] << " ";
        }
        std::cout << std::endl;
    }
    // 释放结果集内存
    mysql_free_result(result);
    // 关闭数据库连接
    mysql_close(conn);
    return 0;
}

4.结果
