vs2019配置连接数据库

  1. C/C++连接MySql数据库
  2. C++连接MySQL数据库
  3. C++实现对MySQL数据库的连接,以及增删改查

一.步骤

  1. 平台改为X64(win32的话配置后会不正确)

  2. 右键项目属性 -> C/C++ -> 常规->附加包含目录。
    添加你的mysql安装目录下的include目录,例如我的是:D:\WAMP\mysql8\include:vs2019配置连接数据库图1

  3. 项目属性 -> 链接器 -> 常规-> 附加库目录。添加MySQL安装目录下的lib目录,例如我的是 D:\WAMP\mysql8\libvs2019配置连接数据库图2

  4. 项目属性 -> 链接器 -> 输入 -> 附加依赖项。添加libmysql.lib文件vs2019配置连接数据库图3

  5. 将 D:\WAMP\mysql8\lib 下的libmysql.dll复制粘贴到C++项目.x64\DEBUG\中vs2019配置连接数据库图4

二.测试(注意将数据库密码等设置为自己本地的配置)

#include "stdio.h"
#include "mysql.h"

int main()
{
    MYSQL* con; //= mysql_init((MYSQL*) 0); 
    MYSQL_RES* res;
    MYSQL_ROW row;
    char tmp[400];
    //database configuartion
    char dbuser[30] = "root";
    char dbpasswd[30] = "20010502"; // it must be    changed
    char dbip[30] = "localhost";
    char dbname[50] = "buct";
    char tablename[50] = "user_approve";
    char* query = NULL;

    int x;
    int y;
    int rt;//return value  
    unsigned int t;

    int count = 0;

    con = mysql_init((MYSQL*)0);

    if (con != NULL && mysql_real_connect(con, dbip, dbuser, dbpasswd, dbname, 3306, NULL, 0)) {
        if (!mysql_select_db(con, dbname)) {
            printf("Select successfully the database!\n");
            con->reconnect = 1;
            query = (char*)(*"set names \'GBK\'");
            rt = mysql_real_query(con, query, strlen(query));
            if (rt) {
                printf("Error making query: %s !!!\n", mysql_error(con));
            }
            else {
                printf("query %s succeed!\n", query);
            }
        }
    }
    else {
        MessageBoxA(NULL, "Unable to connect the database,check your configuration!", "", NULL);
    }

    //sprintf(tmp, "insert into %s values(%s,%d,%d)", tablename, "null", x, y); //注意如何向具有自增字段的数据库中插入记录
    sprintf(tmp, "insert into bl values(null,'x','x','x','x')");


    rt = mysql_real_query(con, tmp, strlen(tmp));
    if (rt)
    {
        printf("Error making query: %s !!!\n", mysql_error(con));
    }
    else
    {
        printf("%s executed!!!\n", tmp);
    }

    sprintf(tmp, "select * from %s", tablename);
    rt = mysql_real_query(con, tmp, strlen(tmp));
    if (rt)
    {
        printf("Error making query: %s !!!\n", mysql_error(con));
    }
    else
    {
        printf("%s executed!!!\n", tmp);
    }
    res = mysql_store_result(con);//将结果保存在res结构体中

    while (row = mysql_fetch_row(res)) {
        for (t = 0; t < mysql_num_fields(res); t++) {
            printf("%s  ", row[t]);
        }
        printf(".............\n");
        count++;
    }

    printf("number of rows %d\n", count);
    printf("mysql_free_result...\n");
    mysql_free_result(res);
    mysql_close(con);
    system("pause");
    return 0;
}
