【问题描述】：
我正在移植一个 MySQL 数据库，我想迁移到一个 Oracle DB 12cRC2。问题是我的某些表的名称长度超过 30 个字符。
一切正常（在我的 schema.rb 文件有点混乱之后）。
我正在使用“全球化”gem 来本地化我的数据库。
当我运行种子时，我的翻译表出现错误，例如：
OCIError: ORA-04043: object "aaaaaaaa_bbbbb_cccc_translations" does not exist
但是当我使用 sqlplus 时，我可以看到我的表没有问题......无论是使用 DESC 还是 SELECT 查询。
我使用oracle-instantclient12.2连接。
我怀疑表名长度，因为其他名称较小的表不会引发执行
我的堆栈：
rails aborted!
ActiveRecord::ConnectionAdapters::OracleEnhanced::ConnectionException: "DESC aaaaaaaa_bbbbb_cccc_translations" failed; does it exist?
