To check if there is any table has lock use the following query:
Abobe query gave us a table names which were present in our query
Now find out the spid (process id) so that we can kill that process manually. Use the following system view:
Find out the session_id (which is our spid) having status as "suspended". In our case it was 77 but it can be different in your case. Now, we can kill this process by kill commnad as follow:
Voila, now our query runs and completes as usually.
