``` create table log(name,dt,time_in,time_out); insert into log values('Noname','2021-03-15','00:12','00:24'); select name, dt, time_in, time_out from log where dt > '2021-03-13' group by dt,time_in having max(time_out); ``` The above `SELECT` returns nothing when I expect one row. If I comment out the `HAVING` clause it works.
