問題分析：
參考：ORA-1031 While Creating A View On A Table On Which The Select Privilege Is Granted Via A Role (文檔 ID 271587.1)
In order to create a view in a schema, that schema must have the privileges necessary to either select, insert, update, or delete rows from all the tables or views on which the view is based. The view owner must be granted these privileges directly, rather than through a role. The reason is that privileges granted to roles cannot be inherited via objects, this is explained also in referenced note 168168.1.
解決方法：
Grant the select privilege on the base table directly rather than through a role: 19:30:36 lc0019999@FS> conn lc0029999/aaaaaa Connected. 19:34:22 lc0029999@FS> grant select on t1 to lc0019999; Grant succeeded.
