我正在尝试使用Simple.OData.Client库从OData V2服务读取数据，但是经过数小时的梳理，我的成功率为零。
pacc_leapaccess_access_log运行此代码在控制台中仅产生SELECT al.* FROM `access_log` AS `al`
LEFT JOIN `pacc_leapaccess_rooms` AS `r` ON al.room_id = r.id
INNER JOIN (
SELECT user_id, room_id, min(created) AS min_date
FROM `access_log`
WHERE `user_id` != 0
GROUP BY user_id, room_id) AS al2
ON al.user_id = al2.user_id AND al.room_id = al2.room_id AND al.created = al2.min_date
WHERE `al`.`created` >= '2019-06-09 00:00:00' AND `al`.`created` <= '2019-06-12 23:59:59';
SELECT al.* FROM `access_log` AS `al`
LEFT JOIN `pacc_leapaccess_rooms` AS `r` ON al.room_id = r.id
INNER JOIN (
SELECT user_id, room_id, max(created) AS max_date
FROM `access_log`
WHERE `user_id` != 0
GROUP BY user_id, room_id) AS al2
ON al.user_id = al2.user_id AND al.room_id = al2.room_id AND al.created = al2.max_date
WHERE `al`.`created` >= '2019-06-09 00:00:00' AND `al`.`created` <= '2019-06-12 23:59:59';
，不打印其他任何内容，并且不会引发任何异常。由于某些原因，第二个打印语句也无法工作...但是为什么呢？
我完全不知道为什么它不起作用。
这实际上是《入门指南》中的代码的副本：https://github.com/simple-odata-client/Simple.OData.Client/wiki/Getting-started-with-Simple.OData.Client
有人可以帮我解决这个问题吗？
