> We have seen large number of orphan views in our production environments. The method
(doDropTable) that is used to drop tables and views drops only the first level child views
of tables. This seems to be the main root cause for orphan views. doDropTable() is recursive
only when the table type is TABLE or SYSTEM. The table type for views is VIEW. The findChildViews
method returns the first level child views. So, doDropTable ignores dropping views of views
(i.e., second or higher level views).
