library ble 功能 com like -- ren target acl

當Oracel的一個新功能出來的時候，我們可能不知道所有與此功能關聯的數據字典名稱，
那麽如何才能得到這些 meta data 的 meta data 呢？

可以通過 dicitonary 來查看：

例如，查找所有 名字裏帶有 memory 的 數據字典名字列表：

SQL> col table_name for a30
SQL> col comments for a80
SQL>select table_name,comments from dictionary where table_name like ‘%MEMORY%‘;
