CREATE TABLE [dbo].[Conditionid](
[Id] [int] NOT NULL,
[ScreenId] [int] NULL,
[ConditionId] [int] NULL,
)


insert into Conditionid（Id,ScreenId,ConditionId）values(1,1,1);
insert into Conditionid（Id,ScreenId,ConditionId）values(2,4,1);
insert into Conditionid（Id,ScreenId,ConditionId）values(3,2,2);
insert into Conditionid（Id,ScreenId,ConditionId）values(4,5,2);
insert into Conditionid（Id,ScreenId,ConditionId）values(5,1,3);
insert into Conditionid（Id,ScreenId,ConditionId）values(6,4,3);

id ScreenId ConditionId
1 1 1
2 4 1
3 2 2
4 4 2
5 1 3
6 4 3


我要的意思是 根据ScreenID查询ConditionID 在ScreenID中包含（1,4） 的ConditionID （1,3）


------解决方案--------------------
你觉得结果应该是什么样，给个手算结果
------解决方案--------------------

SQL code

SELECT DISTINCT ConditionId FROM Conditionid WHERE ScreenId IN (1,4)
------解决方案--------------------
select * ftom [ConditionID] where ScreenID in(1,4) and ConditionId in (1,3)
------解决方案--------------------

不不 理解的意思错了 条件 是ScreenID中有(1,4) 查询出的结果是ConditionID是1和3


3楼的结果是正确的

同时满足……

求交集
SQL code
SELECT ConditionidFROM ConditionidWHERE ScreenId = 1INTERSECTSELECT ConditionidFROM ConditionidWHERE ScreenId = 4
