如何在 HANA SQL 中編寫 CASE WHEN COUNT

Question

以下列給我計數：

COUNT("COMPLIANCE"."CD_ALL"."ProductCode") As "Active Contracts"

但是，我想將計數總數放入桶中。 這是我嘗試過的：

case when (COUNT("COMPLIANCE"."CD_ALL"."ProductCode")) between 0 and 10 then '10 or less',

case when (COUNT("COMPLIANCE"."CD_ALL"."ProductCode")) between 11 and 20 then '11-20',

等等...

我在這里做錯了什么？

Answer 1

我認為你想要一個單一的case表達：

(case when (COUNT("COMPLIANCE"."CD_ALL"."ProductCode")) <= 10 then '10 or less'

      when (COUNT("COMPLIANCE"."CD_ALL"."ProductCode")) <= 20 then '11-20'
      else 'That many!!!'
end) as count_bucket
