> Here is the reproducible case. The following query is failing:
> SELECT entity_id,
> NTH_VALUE(user_id,1) WITHIN GROUP (ORDER BY last_read_date DESC) as nth1_user_id,
> NTH_VALUE(user_id,2) WITHIN GROUP (ORDER BY last_read_date DESC) as nth2_user_id,
> NTH_VALUE(user_id,3) WITHIN GROUP (ORDER BY last_read_date DESC) as nth3_user_id,
> count(*)
> FROM TEST.TEST
> WHERE id='00Dx000000091CU'
> AND entity_id in ('0D5x0000006ARCN','0D5x0000006AQrO')
> GROUP BY entity_id;
> Current Output:
> ============
