Answer 1

試試這個使用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

有數據的非常samll樣品，所以我不知道我這樣做是正確的，但與工會的幫助下聯接我得到這個：

創建並填充示例表（請保存我們這一步在你未來的問題）：

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

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

查詢：

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 

結果：

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