Bowzerという列を持つ というテーブルがありますType。

このクエリを実行しようとすると、SSMS は列を認識しませんType。

これが私のクエリです

update Bowzer
set inserted_by = ISNULL(inserted_by, 'Auto')
where (bowzer_id = 8 and inserted_by is null and type='CRUDE')

ここでは、列が認識されずType、エラーが発生します

列名のタイプが無効です

この列名は許可されてTypeいませんか?

また、Inserted_By列がnullかどうかを確認してから値に置き換えたいAuto

それ、どうやったら出来るの？

null かどうかを確認するには、Case を使用します

Update Bowzer set inserted_by  = Case When inserted_by IS NULL THEN 'Auto' Else inserted_by End
where (bowzer_id = 8 and inserted_by is null and [type]='CRUDE')
