Question

我需要将这个Linq OrderBy语句翻译成SQL：

list = list.OrderByDescending(x => x.Gender == "f" && x.IsCouple == 0)
           .ThenByDescending(x => x.ApprovalRejectedDate)
           .ThenByDescending(x => x.Id);

只需：

ORDER BY x.Gender, x.IsCouple, x.ApprovalRejectedDate, x.Id

返回不同的顺序，因为第一组标准需要匹配在一起。

我在SQL中如何做到这一点？

Answer 1

order by
 case when x.Gender = 'f' and x.IsCouple = 0 then 1 else 0 end,
 x.ApplrovalRejectedDate desc,
 x.Id desc

MS SQL OrderBy设置标准组
