SQL查詢的結果顯示使用的記錄設置

Question

我有一個表像下面

商品

現在我有另一個名爲表

工作表

而且還有一個多對多的關係BW工作列表和商品

Worklist_commodities

現在我想所有未排除的商品，但如果商品是使用在工作清單中，它也被標記爲排除，那麼我也想在結果集中加載結果。

那麼加載結果的最終查詢是什麼。問題可以通過工會輕鬆解決，但我不使用聯合，因爲我使用了某種不具有聯合功能的ORM。

SQL UNION查詢我用來獲取結果集，我想會得到相同的結果，而不UNION

`SELECT this_.ID as ID, 
     this_.Name AS Name, 
     this_.ParentID AS ParentID, 
     this_.IsExcluded AS IsExcluded 
     FROM INFO_Commodities this_ WHERE this_.IsExcluded = 0 
    UNION 
    SELECT this_.ID as ID, 
     this_.Name AS Name, 
     this_.ParentID AS ParentID, 
     this_.IsExcluded AS IsExcluded 
     FROM INFO_Commodities this_ WHERE this_.IsExcluded = 1 AND this_.ID IN 
    (SELECT wc.[CommodityID] 
    FROM SWF_WorkLists as w INNER JOIN SWF_WorkListCommodities AS wc on w.ID 
    = wc.WorklistID WHERE wc.[CommodityID] = this_. ID) 

`

Answer 1

您可以使用FULL JOIN（我的例子是UNION ALL，但可以更換1=0A.ID = B.ID AND A.Name=B.Nama AND ...）

WITH A AS(
    SELECT this_.ID as ID, 
    this_.Name AS Name, 
    this_.ParentID AS ParentID, 
    this_.IsExcluded AS IsExcluded 
    FROM INFO_Commodities this_ WHERE this_.IsExcluded = 0 
), B AS (
    SELECT this_.ID as ID, 
    this_.Name AS Name, 
    this_.ParentID AS ParentID, 
    this_.IsExcluded AS IsExcluded 
    FROM INFO_Commodities this_ WHERE this_.IsExcluded = 1 AND this_.ID IN 
    (SELECT wc.[CommodityID] 
    FROM SWF_WorkLists as w INNER JOIN SWF_WorkListCommodities AS wc on w.ID 
    = wc.WorklistID WHERE wc.[CommodityID] = this_. ID) 
) 
SELECT 
    ID  = COALESCE(A.ID, B.ID), 
    Name = COALESCE(A.Name, B.Name) 
FROM A 
FULL JOIN B ON 1 = 0
