im using sys.dm_exec_sessions to show me all current sessions ( instead of using sp_who2). the problem is that sys.dm_exec_sessions doesnt have the database name or id. where can i map the spid to , to get the db name?

Hello Smith,

Can you check whether this query gives out the desired results you want?

select

es.session_id, sp.spid, sp.dbid, object_name(dbid)

from

sys.dm_exec_sessions es inner join sys.sysprocesses sp on es.session_id = sp.spid

Thanks

Lucky

Correction: you should use db_name(dbid), not object_name

But the question was, and is how to get it from sys.dm_exec_sessions. You are joining to the sysprocesses which in deprecated by MS SQL Server 2012 to the sys.dm_ ... views

How about this:

select

es.session_id,

er.session_id,

er.dbid,

db_name(er.dbid)

from

sys.dm_exec_sessions es

inner join sys.dm_exec_requests er on es.session_id = er.session_id;

Edit: Corrected a couple of aliases.

Nope. sorry but you have sp. in there and no AS for sp. GTry running it yourself

Also, didn't see you suggest any alternatives, so keep your snarkiness to yourself please.

This should do it

select

es.session_id,

er.database_id,

db_name(er.database_id) AS DBName

from

sys.dm_exec_sessions es

inner join sys.dm_exec_requests er on es.session_id = er.session_id;

This query (joining sys.dm_exec_sessions to sys.dm_exec_requests) is functionally different from querying sys.sysprocesses.

sys.sysprocesses has the current database context for every session (regardless of whether there are any currently-executing requests).

However, joining to sys.dm_exec_requests means that you will only get results for sessions with currently-executing requests.

You'll get fewer roes using sys.dm_exec_requests, and potentially filter out valid results.

As of now, I think that the dbid data in sys.sysprocesses is uniquely available in that view, and not available in any other 2012 DMV.

sys.dm_exec_requests will show only the currently executing processes not the one waiting for connections
