嘿我在PHPstorm中连接FTP时遇到问题.我知道我有正确的参数,因为它适用于其他FTP客户端.
我得到的错误是:无法列出文件夹" ftp://real-meal.com/ "的内容
端口设置为21,应该是.我知道我有正确的用户名/密码.任何想法可能是什么问题？
这是日志文件:

有没有办法避免为此查询使用临时表：
SELECT url,count(*) as sum
FROM `digital_pageviews` as `dp`
WHERE `publisher_uuid` = '8b83120e-3e19-4c34-8556-7b710bd7b812'
GROUP BY url
ORDER BY NULL;
这是我的表架构：
create table digital_pageviews
(
id int unsigned auto_increment
primary key,
visitor_uuid char(36) null,
publisher_uuid char(36) default '' not null,
property_uuid char(36) null,
ip_address char(15) not null,
referrer text null,
url_delete text null,
url varchar(255) null,
url_tmp varchar(255) null,
meta text null, …
