Question

我有2个表，我想编写一个查询来计算列结果，该列将第一张表中的每一列与第二张表进行比较。

DECLARE @result TABLE (A INT, B INT, C INT, D INT, E INT, F INT, G INT)
INSERT INTO @result ( A, B, C, D, E, F, G) 
VALUES ( 2, 14,19,20,35,41,15)

DECLARE @bet TABLE (A INT, B INT, C INT, D INT, E INT, F INT)
INSERT INTO @bet ( A, B, C, D, E, F) 
VALUES( 2, 14,19,20,35,41 ),
      ( 5, 14,15,20,33,46 ),

Answer 1

这应该可以完成工作：

SELECT STUFF((
    SELECT ','+CAST(X as varchar(4)) [*]
    FROM (VALUES (A),(B),(C),(D),(E),(F)) T(X)
    WHERE X IN (
        SELECT X
        FROM @result
        UNPIVOT (X FOR Y IN (A,B,C,D,E,F,G)) P
    )
    ORDER BY X FOR XML PATH('')), 1, 1, '') 
FROM @bet

结果：

Result
-------------------
2,14,19,20,35,41
14,15,20
NULL

我怎么写这样的结果
