What's blocking “Select top 1 * from TableName with (nolock)” from returning a result?

Question

I\'m currently running the following statement

select * into adhoc..san_savedi from dps_san..savedi_record

It\'s taking a painfully long time a

Answer 1

Find the session_id that is performing the select into:

SELECT r.session_id, r.blocking_session_id, r.wait_type, r.wait_time
  FROM sys.dm_exec_requests AS r
  CROSS APPLY sys.dm_exec_sql_text(r.plan_handle) AS t
  WHERE t.[text] LIKE '%select%into%adhoc..san_savedi%';

This should let you know if another session is blocking the select into or if it has a wait type that is causing a problem.

You can repeat the process in another window for the session that is trying to do the select. I suspect Martin is right and that my earlier comment about schema lock is relevant.
