在 Clickhouse 中按备选方案进行滞后/领先分区和排序
[英]Lag/lead partition by and order by alternatives in Clickhouse
问题描述
我有一个看起来像这样的表：
对于每一行，我想为相同的 trans_type、channel 和 country 计算前面的 event_date Gross_sum 值。 新的数据片段：
channel="Affiliate", country="CA" and trans_type="conversion"
应该是这样的：
event_date trans_type channel country gross_sum prev
'2021-12-02' conversion AFFILIATE CA 120 100
'2021-12-01' conversion AFFILIATE CA 100 900
'2021-11-30' conversion AFFILIATE CA 900 800
也就是我要执行标准滞后function，现在我不可用：
select lag(gross_sum) over(partition by event_date, trans_type, channel, country order by event_date desc) from table
我需要一个聚合 function 例如数组 function 但不是邻居 function。 邻居或类似的非聚合函数不能很好地处理分组变量，我需要聚合，以便将来我可以删除 trans_type、channel。 表中的国家列，并查看每个日期的总和（总和）及其前面的值。
感谢您的帮助！
