ClickHouse Union 全部例外
ClickHouse Union All exception
我写了用 union all 创建视图表达式。

请求的视图中的所有列都存在。我对这个例外一无所知
Code: 386, e.displayText() = DB::Exception: There is no supertype for types String, DateTime because some of them are String/FixedString and some of them are not (version 19.15.3.6 (official build))
哪里会出错？像 select 1 as one union all select 2 as one 这样的简单联合效果很好。我唯一发现的是错误是由于 Array Join 引起的，当类型转换时。
最初，我认为这是由于 EventFlag 的 NULL 转换造成的，e.t.c，同时合并并用 '' 替换 NULL。但一切都没有改变
求助，求助
p.s。对不起我的英语
select now() union all select ''
Code: 386. DB::Exception: Received from localhost:9000.
DB::Exception: There is no supertype for types DateTime, String
because some of them are String/FixedString and some of them are not.
