Vertica 常用相关命令

1.命令行连接Vertica

 vsql -p port -U user -w password -h hostname

2.查询Vertica的所有session

   dbadmin  => SELECT * FROM sessions;

3.关闭session_id为 stress05-27944:0xc1a 的session

   dbadmin  => SELECT CLOSE_SESSION('stress05-27944:0xc1a');

4.关闭所有session

   dbadmin => SELECT CLOSE_ALL_SESSIONS();

5.关闭当前用户的session

  dbadmin  => SELECT close_user_sessions('u1');

6.命令行执行sql脚本

 dbadmin => \i /tmp/file.sql

案例1 当发生session死锁的时候解决方法：

          dbadmin用户登录，使用select * from sessions;命令查看session情况，死锁的记录通过SELECT CLOSE_SESSION('stress05-27944:0xc1a');方式关闭掉session;
