how to query closed session in vertica

Question

Is there a way to query closed session record in vertica database? It seem there is only a table store the current active sessions:

select * from sessions

Answer 1

您要查看dc_session_ends表。

SELECT * FROM dc_session_ends;

它显示了会话关闭的时间，会话所在的节点，session_id和user_id / user_name。

要对其进行测试，可以查询当前的session_id。

SELECT session_id FROM current_session;

如果使用该session_id查询dc_session_ends表，则不会显示任何内容，但是如果您关闭会话，然后重新连接，则会看到session_id出现。

SELECT * FROM dc_session_ends WHERE session_id = '<session_id>';
