如何利用MySQL和C++开发一个简单的批量解压功能

#include <mysql/mysql.h>

MYSQL* conn;

int main()
{
    conn = mysql_init(NULL);
    if (conn == NULL)
    {
        fprintf(stderr, "mysql_init() failed
");
        return 1;
    }

    if (mysql_real_connect(conn, "localhost", "user", "passWord", "database", 0, NULL, 0) == NULL)
    {
        fprintf(stderr, "mysql_real_connect() failed
");
        return 1;
    }

    // 连接成功，继续执行后续代码

    mysql_close(conn);
    return 0;
}

MYSQL_RES* res;
MYSQL_ROW row;

if (mysql_query(conn, "SELECT path FROM files")) // 替换为实际的查询语句
{
    fprintf(stderr, "mysql_query() failed
");
    return 1;
}

res = mysql_use_result(conn);

while ((row = mysql_fetch_row(res)))
{
    // 获取文件路径并进行解压操作
    // 为了简化示例，这里只打印文件路径
    printf("Unzipping file: %s
", row[0]);
}

mysql_free_result(res);

#include <iOStream>
#include <fstream>
#include <sstream>
#include <cstdlib>

void unzipFile(const std::string& filePath)
{
    std::string command = "unzip " + filePath;
    std::cout << "Executing command: " << command << std::endl;
    std::system(command.c_str());
}

// 在前面的代码中的while循环中调用该函数进行解压
unzipFile(row[0]);

    }

    if (mysql_query(conn, "SELECT path FROM files"))
    {
        fprintf(stderr, "mysql_query() failed
");
        return 1;
    }

    MYSQL_RES* res;
    MYSQL_ROW row;

    res = mysql_use_result(conn);

    while ((row = mysql_fetch_row(res)))
    {
        unzipFile(row[0]);
    }

    mysql_free_result(res);
    mysql_close(conn);
    return 0;
}
