こんにちは、Sybase 16 を使用しています。
この CTE を実行すると、「更新の近くで構文エラーが発生しました」というエラーが表示されます...
With Remove_Dup_Nov13(pk_viewing_prog_instance_fact, Rank_instance)
As
(Select pk_viewing_prog_instance_fact,
row_number()over(partition by dk_programme_instance_dim, subscriber_id, account_number,
instance_start_date_time_utc, instance_end_date_time_utc, instance_duration
order by dk_programme_instance_dim, subscriber_id, account_number,
instance_start_date_time_utc, instance_end_date_time_utc, instance_duration) rank_instance
From Viewing_Cribs_Nov13
)
Update Viewing_Cribs_Nov13
Set a.Rank_instance = b.Rank_instance
from Viewing_Cribs_Nov13 as a
inner join
Remove_Dup_Nov13 as b
on a.pk_viewing_prog_instance_fact = b.pk_viewing_prog_instance_fact;
提案してください。
