Query plans possess vital information which can help a DBA to make optimization decisions.

The T-SQL below will retrieve the query plan for database of your choice. By extending the where clause in the sub query you can be more precise about the query plans you return based on particular commands for example. The sub query could even be replaced with your own SPID.

select query_plan
from sys .dm_exec_requests as er
cross apply sys. dm_exec_query_plan(er .plan_handle)
where session_id in ( select spid from sys. sysprocesses where dbid = DB_ID('database_name' ))

Happy viewing :)
