SQL server connection and blocking finding script

 

-- For SQL 2000
select db_name(dbid),* from master.dbo.sysprocesses where spid> 51 and status <>'sleeping' -- and blocked <>0


-- To find the spid and connections which are all running
select db_name (r.database_id),r.command,r.wait_resource,s.status,s.session_id,
r.blocking_session_id,r.last_wait_type,r.open_transaction_count,sql_handle,
* from sys.dm_exec_sessions s  join sys.dm_exec_requests r
on s.session_id =r.session_id 
--where s.status <>'sleeping'
and s.session_id >=51 
and s.session_id  <>@@SPID -- exclude your session

-- to find the blockings
select db_name (r.database_id),r.command,r.wait_resource,s.status,s.session_id,
r.blocking_session_id,r.last_wait_type,r.open_transaction_count, 
* from sys.dm_exec_sessions s join sys.dm_exec_requests r
on s.session_id =r.session_id 
where r.blocking_session_id<>0 -- list blocking

select *  FROM sys.dm_exec_requests

-- to find the code which is run by spid connections
SELECT T.TEXT As Query,
R.session_id,
R.status,
R.command
FROM sys.dm_exec_requests R
CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS T
WHERE session_id = (54)

-- OR (going to be deprecated)
