我想將此 EF 代碼轉(zhuǎn)換為 SQL 命令：var parents = db.Fuels.Select(A => A.Parent).Distinct();var data = db.Fuels.Where(B => !parents.Any(A => A == B.ID)) .OrderBy(A => A.Type);我嘗試編寫SQL命令，但它不起作用：select *from Fuel as awhere id not in (select id from Fuel as b where a.ID = b.Parent)表結(jié)構(gòu)：ID INT PK,Name NVARCHAR(50) Checked,Parent INT FK表數(shù)據(jù)我想要這個輸出

這是您正在尋找的查詢：
;with parents as (select distinct parent as ID from @Fuel)
select * from @Fuel where id not in (select Id from @Fuel where Id in(select Id from
parents))
