Whats the difference between sysprocesses and dm_exec_requests. I can see both showing different statuses at the same time. What would be the order of execution.
Say, sys process shows runnable and dm_exec_requests ahows running.
Help me to understand the order of the way it looked into...

Remark from BOL (2-nd ref)
This SQL Server 2000 system table is included as a view for backward compatibility. We recommend that you use the current SQL Server system views instead. To find the equivalent system view or views, see Mapping SQL Server 2000 System Tables to SQL Server 2005 System Views. This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

Thanks for your reply!!!
However, still not clear on the descrepancy of the results. Could you please correct me if my understanding is wrong...

you should use the DMVs to get the most reliable results.
sysprocesses itself is a backward compatibility view. It has more statuses documented in BOL than sys.dm_exec_requests.
sys.dm_exec_sessions also has a status column.
sysprocesses has been replaced by :
select *
from sys.dm_exec_requests ER
left join sys.dm_exec_sessions ES
on ES.session_id = ER.session_id
left join sys.dm_exec_connections EC
on EC.session_id = ER.session_id
--where ER.session_id = 51
order by ER.session_id
