I THINK everything is right with this CTE query. Example data here: <https://termbin.com/9y2s> Now for the results: ``` ┌───────────┬───────────┬─────────────────┐ │ EventDate │ EventHour │ AccidentsInHour │ ├───────────┼───────────┼─────────────────┤ │ 4/16/2021 │ 2 │ 1 │ │ 4/16/2021 │ 3 │ 2 │ │ 4/16/2021 │ 5 │ 4 │ │ 4/16/2021 │ 6 │ 2 │ │ 4/16/2021 │ 7 │ 4 │ │ 4/16/2021 │ 8 │ 7 │ │ 4/16/2021 │ 9 │ 2 │ │ 4/16/2021 │ 10 │ 5 │ │ 4/16/2021 │ 11 │ 5 │ │ 4/16/2021 │ 12 │ 1 │ │ 4/16/2021 │ 13 │ 14 │ │ 4/16/2021 │ 14 │ 5 │ │ 4/16/2021 │ 15 │ 11 │ │ 4/16/2021 │ 16 │ 12 │ │ 4/16/2021 │ 17 │ 5 │ │ 4/16/2021 │ 18 │ 8 │ │ 4/16/2021 │ 19 │ 4 │ │ 4/16/2021 │ 20 │ 6 │ │ 4/16/2021 │ 21 │ 5 │ │ 4/16/2021 │ 22 │ 6 │ │ 4/16/2021 │ 23 │ 4 │ │ 4/16/2021 │ 24 │ 12 │ └───────────┴───────────┴─────────────────┘ ``` 24 seems to represent 12nooon. Can you explain which part of the substitution does that? These CTE things are really, really cool and powerful!
