問這個問題的初衷是希望能夠在Oracle中通過視圖關聯多張表，然后將結果集緩存到TimesTen.

不過答案是不支持，在Cache User Guide第245頁，明確指出：

TimesTen supports views and materialized views, but it cannot cache an Oracle Database view. TimesTen can cache an Oracle Database materialized view in a user managed cache group without the AUTOREFRESH cache group attribute and PROPAGATE cache table attribute. The cache group must be manually loaded and flushed.

視圖是不支持的，物化視圖支持，但有太多限制條件。所以視圖之類的就別考慮的，原因應該是視圖不能保證主鍵或唯一索引
