How to find the logins,program name and databases for a session id?

Question

I used the following the following query.
select pr.spid ,pr.dbid,pr.program_name,pr.loginame,ss.session_id,ss.host_name,ss.login_time,db.name from master.dbo.sysprocesses pr,sys.dm_exec_sessions ss,sys.databases db
where pr.spid = ss.session_id and pr.dbid = db.database_id
order by ss.login_time desc
Is spid in master.dbo.sysprocesses the same as session_id in sys.dm_exec_sessions and dbid in master.dbo.sysprocesses the same as database_id in sys.databases?
My intention is to get the active sessions with the program name,login Name and database name corresponding to the session?

Answer 1

1)Why you included the clause session_id > 50?
Sessions with session_id <= 50 are system processes.
2)Is there any problem with the query I used?
You query was better than Latheesh's. To wit, his query will only show the database for sessions who are actually running something.
On SQL 2005 and SQL 2008, this is the best solution:
SELECT  des.session_id, des.[status], des.login_name,
        d.name AS database_name, des.program_name
FROM    sys.dm_exec_sessions des
JOIN    sys.sysprocesses p ON des.session_id = p.spid
LEFT JOIN sys.databases d ON p.dbid = d.database_id
WHERE   des.session_id > 50
  AND   p.ecid =0
ORDER BY des.session_id;
The condition p.ecid = 0 is needed to weed out extra rows when there are parallism in force.
On SQL 2012, you don't need sysprocesses, but this works:
SELECT  des.session_id, des.[status], des.login_name,
        d.name AS database_name, des.program_name
FROM    sys.dm_exec_sessions des
LEFT JOIN sys.databases d ON des.database_id = d.database_id
WHERE   des.session_id > 50
ORDER BY des.session_id;
