Question

我需要帮助在Sql Server 2014中进行查询。我有下表

ID           Part
SP470PR 
SP470PR     181607
SP470PR     1030

我需要将结果显示如下：

ID           Part
SP470PR     181607
SP470PR     1030    
181607      SP470PR
181607      1030    
1030        181607
1030        SP470PR

有人可以帮我解决这个问题吗？我尝试使用Lead功能，但我无法得到我想要的结果？

谢谢

Answer 1

尝试使用CROSS JOIN： -

Select * from table
where part is not null
union all
Select distinct a.part as ID,b.ID as part from
(select part from table) a 
cross join
(select id from table) b
where part is not null
union all
Select a.part as ID,b.part from
(select part from table where part is not null) a
cross join
(select part from table where part is not null) b
where a.part<>b.part

有一个非常小的数据样本，所以我不确定我是否正确，但在联盟的帮助下，我得到了这个：

创建并填充样本表（请在将来的问题中保存此步骤）：

DECLARE @T AS TABLE
(
    ID nvarchar(10),
    Part nvarchar(10)
)

INSERT INTO @T VALUES
('SP470PR', NULL), 
('SP470PR', '181607'), 
('SP470PR', '1030')

查询：

SELECT ID, Part
FROM @T 
WHERE Part IS NOT NULL
UNION 
SELECT Part, ID
FROM @T 
WHERE Part IS NOT NULL
UNION 
SELECT t1.Part, t2.Part
FROM @T t1
INNER JOIN @T t2 ON t1.Id = t2.Id
WHERE t1.Part <> t2.Part
ORDER BY ID DESC, PART DESC

结果：

ID      Part
SP470PR 181607
SP470PR 1030
181607  SP470PR
181607  1030
1030    SP470PR
1030    181607
