關於 ProductModel.CatalogDescription xml 資料行
以 Adventure Works 為例，腳踏車產品型號的型錄描述會以 XML 格式儲存在 CatalogDescription 資料行中。每一個產品型號都可包含數種個別的產品。例如，Road 450 是一個腳踏車產品型號，它包含了好幾種腳踏車，例如 Road 450 red 25 及 Road 450 Green 48。在腳踏車產品型號之間的主要差異是在顏色及尺寸。
您可以查詢這些產品的描述，將 XSL 轉換套用到這些描述，進而產生線上型錄。儲存在 CatalogDescription 資料行中的型錄資訊不會使用業界標準的結構描述。因此，若有需要，您可以撰寫查詢來建立業界標準的 XML 產品型錄。
這是 xml 類型的資料行。您可以在 Microsoft 網站檢視此資料行所使用的結構描述。此資料行使用 AdventureWorksProductModelDescription 及 ProductModelWarrAndMain XML 結構描述。
