【产品名称】oceanbase-ce
【产品版本】3.1
【问题描述】
$ mysql -h 127.1 -u root@obmysql -P 2881 -p -c -A oceanbase -Ns
MySQL [oceanbase]> show databases;
oceanbase
information_schema
mysql
test
问题一：
这个-Ns是什么意思？
问题二：
MySQL [oceanbase]> use test
ERROR 1049 (42000): Unknown database
问题三：
MySQL [oceanbase]> select user,host from mysql.user;
ERROR 1146 (42S02): Table ‘mysql.user’ doesn’t exist
首先 加上-Ns后，登录直接进入命令行模式，没有如下信息：
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 19
Server version: 5.7.1 OceanBase 3.1.2 (r10000392021123010-d4ace121deae5b81d8f0b40afbc4c02705b7fc1d) (Built Dec 30 2021 02:47:29)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
然后 麻烦确认下test库是否存在
最后 麻烦确认下表mysql.user是否存在，建议退出重新登录试下。
