嗨，上面我的結果集的複雜查詢。直到這裏我能夠實現。

請先看看前2條記錄。第一排的物品1 = 2行的SRID.if物品1反之亦然和ITEM2的SRID的ITEM2是任何順序相同的，我需要從itand造成的任何一條記錄應該是

SRID Interaction Flag Flag2 items1      items2 
    16222 abc B 4 1852311000001100 19836811000001100 
    18599 abc B 4 1852311000001100 10368611000001100 
    19518 abc A 2 1852311000001100 1592311000001100 
    19518 abc A 2 1852311000001100 19836811000001100

取決於其他人呢數據是這樣的，但這可能工作....

WITH SourceData AS 
(
    SELECT 
    * 
    FROM ( VALUES (16222, 'abc', 'B', 4, 1852311000001100, 19836811000001100) 
        ,(16222, 'abc', 'B', 4, 19836811000001100, 1852311000001100) 
        ,(18599, 'abc', 'B', 4, 1852311000001100, 10368611000001100)

) 
,CTE AS

    SELECT DISTINCT
