SQL LEFT OUTER JOIN與Where子句的問題

Question

我在數據庫中有兩個表。 包含產品信息的產品表和另一個表SiteProduct，其中包含名為ProductID的第一個表的ID以及存儲哪個站點在其目錄中具有哪些產品的附加SiteID。 我需要在網站上創建一個網格，該網格將顯示所有產品，然后選中或取消選中該網站是否在其目錄中包含該產品。 我需要在一個查詢中執行此操作。 請參閱下面的查詢，我正在嘗試使用左外連接來加入Product表和SiteProduct表。 但是，使用此查詢時，返回的唯一結果是在SiteProduct表中具有SiteID 100的記錄的產品。所以說有100個產品，SiteProduct表有50個產品用於SiteID 100，我只得到50個結果當我需要查看所有100.我需要查詢以顯示所有產品，然后顯示空值或者某些東西，如果SiteID100在SiteProduct表中沒有該條目。 同樣，這必須在一個查詢中完成，我不想為每個產品對SiteProduct表進行后續SELECT調用。 理想情況下，我希望這可以作為LEFT OUTER JOIN工作，但我願意接受其他可能性。

請在下面查看我的查詢，謝謝。

Answer 1

我最后在where子句中使用多個in語句來解決這個問題。
