SQL/HIVE - 解決の問題（小さな変更） - パーティション

Question

以下のコードがあります。これは主にテストしたいくつかのシナリオで正しく機能します。

しかし、私が完了するまで、N-CO（非補完）のための数をカウントしようとしていますが、それは代わりに3

の5を返すと私はカウントするように別の列を作成しようとしています下の例部分的には2です。

これまでどんな理由がありましたか？ 変更する必要があるのは何ですか？

Answer 1

select Identifier 
     ,COMP_id 
     ,count(case when SN_Status = 'N-CO'  then 1 end) as count_N_CO 
     ,count(case when SN_Status = 'PARTIALLY' then 1 end) as count_PARTIALLY 
     ,count(case when SN_Status = 'COMP'  then 1 end) as is_COMP 

from (select Identifier 
       ,SN_Status 
       ,count(case when SN_Status = 'COMP' then 1 end) over 
       (
        partition by Identifier 
        order by  CreatedDate, case when SN_Status = 'COMP' then 1 else 0 end, CompletedDate 
        rows   between unbounded preceding and 1 preceding 
       ) + 1 as COMP_id 

     from #temp 
     ) t 

group by Identifier 
      ,COMP_id
