如何在 HANA SQL 中编写 CASE WHEN COUNT

Question

The following column gives me counts:

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

However, I want to put the count totals into buckets. This is what I tried:

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',

and so on...

What am I doing wrong here?

Answer 1

I think you want a single case expression:

(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
