#description: 该case是为了验证内部表是否符合规范
## 规范: 1.基础系统表保持OB既有风格，以’__all_’开头，统一用单数、主动、第一人称一般时（不搞ing、ed、s等）
## 2.虚拟表保持OB既有风格，以’__all_virtual’或者’__tenant_virtual’开头，统一用单数、主动、第一人称一般时（不搞ing、ed、s等）。__all_virtual为展示系统内部信息的虚拟表，支持直接查询，可基于此建立兼容其他数据库的视图；__tenant_virtual虚拟表为支持特定操作（如show）而创建的，一般不支持直接查询。
## 3.基础系统表和虚拟表属OB系统内部实现，其定义要考虑版本平滑升级和扩展性的需要，不建议DBA及普通用户直接使用这两类对象。后续会增加对该类对象可见性的控制，在通常的show table等外部命令的一般性输出中不显示内部对象。
## 4.明确_all_table对象的类型，区分基础系统表、用户表、虚拟表、系统视图、用户视图，同时确认各种对象table_id的范围符合设计。
## 5.提供给DBA普通用户的信息，通过定义相应的视图来实现。视图的命名规则及模式按照需要兼容的目标数据库的相应视图来确定，保持定义的稳定。除MySQL兼容的视图外，系统诊断信息相关的视图，命名统一采用类Oracle的方式。
## 6.虚拟表的名称和字段进行局部调整，如对于需要展示集群所有节点信息的虚拟表，统一使用server的唯一标识(`svr_ip`, `svr_port`)为分区键，部分特定的字段名称也加以统一（当前某些地方用host/port，有些用svr_ip/svr_port）；如果虚拟表包含`tenant_id`, `svr_ip`, `svr_port`字段，则主键包含这些字段。
