I am trying to get the ranking or grouping to count like in the custom_ranking column:
I want it to count the rank like in the row custom_ranking, but everything I keep trying is counting it in the current_ranking row.
I am currently using this:
,row_number() OVER (partition by custID, propID ORDER BY trans_type desc, record_date desc) AS RANKING
根据您的样本数据,这将是:
dense_rank() over (partition by custid order by propid)
