How do I use `sys.dm_exec_connections` in combination with SUSER_SNAME()?
As others have already pointed out the info you want is in sys.dm_exec_sessions. However if you want to pull from both DMVs this would work:


SELECT c.connect_time
 , s.login_time
 , s.host_name
 , s.login_name
FROM sys.dm_exec_connections AS c
   JOIN sys.dm_exec_sessions AS s ON c.session_id = s.session_id
