我尝试将管理员在用户管理资料页面上看到的“信任等级 3 要求”报告重构为一个数据探索器（Data Explorer）查询。
这样做的动机是，借助 允许将查询限制为当前用户 ID 的新功能，TL2 用户现在可以自行查看进度，而无需再向工作人员询问。
该查询使用了站点设置中配置的值，并与用户的统计数据进行比较。我注意到管理视图与查询结果之间存在一些细微差异，这可能是由四舍五入造成的。TL3 晋升的逻辑相当复杂，因此 SQL 语句必然略显繁琐，可能仍存在错误。我非常希望能收到任何反馈，以便我纠正这些错误。
以下是当前的查询：
目前，此查询并未限制为 current_user_id，因为为了测试方便，需要能够选择要运行查询的用户。若要更改这一点，只需将第二行改为 -- current_user_id :user_id 即可。
-- [params]
-- user_id :user_id
