Change where clause filter based on prompt?

Question

Hi,
I am trying to change my where clause filter based on a prompt selected. What I want to do logically looks like this - although it doesn't work as it is not valid case statement syntax:
select *
from table t
where t.calc_result_info_key in (case when :product_prompt = 'GAS' then (310, 160, 4000)
                                 else (320, 330, 340, 350, 170, 180, 190, 200, 4010, 4020, 4030, 4040)  end)Is there any way to change filter logic like this?

Answer 1

The good old ugly OR statement.
select *
from table t
where
      t.calc_result_info_key in (310, 160, 4000)
         and
      :product_prompt = 'GAS'
   or
      t.calc_result_info_key in (320, 330, 340, 350, 170, 180, 190, 200, 4010, 4020, 4030, 4040)
   and
      (:product_prompt != 'GAS' or :product_prompt is null)
   )
