SQL Server-删除组中为空的结果

不确定标题是否恰当，但我有点不确定如何用词。我有一个

情况表

，我需要根据

情况组

给出传递的数据显示某些问题

我传入的数据如下所示：

----------------------------------------------------
| CircumstanceTypeGiven | CircumstanceValueGiven |
----------------------------------------------------
|      Equipment        |           X            |
----------------------------------------------------
|      Customer         |        BEEFORE         |
----------------------------------------------------

--------------------------------------------------
| ID | CircumstanceType  |  GroupID  |  Value    |
--------------------------------------------------
| 1  |    Equipment      |    1      |  Reefer   |
--------------------------------------------------
| 2  |    Customer       |    1      |  BEEFOR   |
--------------------------------------------------

--------------------------------------------------
| ID | CircumstanceGroupID  |    QuestionID      |
--------------------------------------------------
| 1  |         1            |         1          |
--------------------------------------------------

--------------------------------------------------
| ID | Question                                  |
--------------------------------------------------
| 1  |  This is my question for Reefer & BEEFOR  |
--------------------------------------------------

我的

环境主管

表如下所示：

----------------------------------------------------
| CircumstanceTypeGiven | CircumstanceValueGiven |
----------------------------------------------------
|      Equipment        |           X            |
----------------------------------------------------
|      Customer         |        BEEFORE         |
----------------------------------------------------

--------------------------------------------------
| ID | CircumstanceType  |  GroupID  |  Value    |
--------------------------------------------------
| 1  |    Equipment      |    1      |  Reefer   |
--------------------------------------------------
| 2  |    Customer       |    1      |  BEEFOR   |
--------------------------------------------------

--------------------------------------------------
| ID | CircumstanceGroupID  |    QuestionID      |
--------------------------------------------------
| 1  |         1            |         1          |
--------------------------------------------------

--------------------------------------------------
| ID | Question                                  |
--------------------------------------------------
| 1  |  This is my question for Reefer & BEEFOR  |
--------------------------------------------------

然后，我得到了一个表，其中包含这样的组的问题ID:

----------------------------------------------------
| CircumstanceTypeGiven | CircumstanceValueGiven |
----------------------------------------------------
|      Equipment        |           X            |
----------------------------------------------------
|      Customer         |        BEEFORE         |
----------------------------------------------------

--------------------------------------------------
| ID | CircumstanceType  |  GroupID  |  Value    |
--------------------------------------------------
| 1  |    Equipment      |    1      |  Reefer   |
--------------------------------------------------
| 2  |    Customer       |    1      |  BEEFOR   |
--------------------------------------------------

--------------------------------------------------
| ID | CircumstanceGroupID  |    QuestionID      |
--------------------------------------------------
| 1  |         1            |         1          |
--------------------------------------------------

--------------------------------------------------
| ID | Question                                  |
--------------------------------------------------
| 1  |  This is my question for Reefer & BEEFOR  |
--------------------------------------------------

我的问题表：

----------------------------------------------------
| CircumstanceTypeGiven | CircumstanceValueGiven |
----------------------------------------------------
|      Equipment        |           X            |
----------------------------------------------------
|      Customer         |        BEEFORE         |
----------------------------------------------------

--------------------------------------------------
| ID | CircumstanceType  |  GroupID  |  Value    |
--------------------------------------------------
| 1  |    Equipment      |    1      |  Reefer   |
--------------------------------------------------
| 2  |    Customer       |    1      |  BEEFOR   |
--------------------------------------------------

--------------------------------------------------
| ID | CircumstanceGroupID  |    QuestionID      |
--------------------------------------------------
| 1  |         1            |         1          |
--------------------------------------------------

--------------------------------------------------
| ID | Question                                  |
--------------------------------------------------
| 1  |  This is my question for Reefer & BEEFOR  |
--------------------------------------------------

所以，我通过了设备类型X和客户价值BEEFOR。我的情况表显示，如果我通过了冷藏和BEEFORE，那么我需要获得

groupID

1的问题。但是，如果只传递了1（我给出的场景），我不希望出现这些问题

下面是SQL：

CREATE TABLE CircumstanceMaster
(
    CircumstanceID INT NOT NULL PRIMARY KEY IDENTITY(1,1),
    CircumstanceGroupID INT NOT NULL,
    CircumstanceType INT NOT NULL,
    CircumstanceValue VARCHAR(MAX) NOT NULL
)
INSERT INTO CircumstanceMaster ( CircumstanceType, CircumstanceGroupID, CircumstanceValue ) VALUES ( 1, 1, 'R' )
INSERT INTO CircumstanceMaster ( CircumstanceType, CircumstanceGroupID,  CircumstanceValue ) VALUES ( 2, 1, 'DEEFOR' )


CREATE TABLE QuestionMaster
(
    QuestionID INT NOT NULL PRIMARY KEY IDENTITY(1,1),
    Question VARCHAR(MAX) NOT NULL
)
INSERT INTO QuestionMaster ( Question ) VALUES ( 'Reefer & DEEFOR question' )


CREATE TABLE CircumstanceQuestion
(
    ID INT NOT NULL PRIMARY KEY IDENTITY(1,1),
    CircumstanceGroupID INT NOT NULL,
    QuestionID INT NOT NULL
)
INSERT INTO CircumstanceQuestion ( CircumstanceGroupID, QuestionID  ) VALUES ( 1, 1 )

declare @given Table(CircumstanceTypeGivenID INT, CircumstanceValueGiven varchar(50))
insert into @given(CircumstanceTypeGivenID,CircumstanceValueGiven) VALUES ( 1, 'X')
insert into @given(CircumstanceTypeGivenID,CircumstanceValueGiven) VALUES ( 2, 'DEEFOR')



select *
from CircumstanceMaster cm
    left outer join @given g on cm.CircumstanceType=g.CircumstanceTypeGivenID and cm.CircumstanceValue=g.CircumstanceValueGiven

当我加入我的

环境主表时，我得到了这个结果。我期望得到结果，但我需要一种方式说“如果同一组中的任何行都有空值，请不要返回任何内容”：

试试这个：

select CircumstanceGroupID 
from CircumstanceMaster cm 
left join @given g on cm.CircumstanceType=g.CircumstanceTypeGivenID and cm.CircumstanceValue=g.CircumstanceValueGiven
group by CircumstanceGroupID
having sum(case when CircumstanceValueGiven is null then 0 else 1 end) = count(*)

回到您的数据库中，您可以找到另一种方法。
如果所有行都有一个偶数为空的值，那么不显示所有结果是什么意思？或者只显示行没有空值
