我无法理解All下面代码中的函数功能，我只想为下面的查询编写 SQL 存储过程..
IQueryable<Situation> situations = db.Situations
.Include("SituationHandicap")
.Include("SituationAttributes")
.Where(x =>
x.Deleted == false &&
x.Published == true &&
x.SituationCategory.Id == C
&& (A.All(a => x.SituationAttributes.Any(sa => a == sa.AttributesId)) ||
A.Any(a => x.SituationAttributes.Any(sa => a == sa.AttributesId)))
&& (H.All(a => x.SituationHandicap.Any(sa => a == sa.HandicapId)) ||
H.Any(a => x.SituationHandicap.Any(sa => a == sa.HandicapId)))
);
我只是混淆了在 SQL 中使用什么来代替 .All() 方法...请回答
我刚刚发现 Linq 查询的 Entity Framework Generated SQL 查询太长了，如下所示

它正在工作，但这不是一个好方法，请建议
