locks with select

Hey I have a terrible problem !!

I have a query, and It doesn't matter if it has finished, the table is still locked. Is there any clause to unlock the share mod lock (force) when the query has finished or any way to ensure that table has no locks to continue with another query or transaction ?

Could you give me any sentence ?

Thanks you !!Also, see if there are any open transactions in your database, or in tempdb if your query references temporary objects:
DBCC OPENTRAN('<your_database>')|||Is there any way to turn the data base in optimistic mode, or to execute that in optimistic mode ?|||Yes (http://www.dbforums.com/showpost.php?p=3690898&postcount=13).

-PatP|||Well, but I have a concurrency problem: Update sentence has been thrown while a select is being executed (of the same table), so the select is locking the update, and the query takes a lot of time, what I want to do, is to execute the query and not to wait a long time to be able to execute the update sentence, guaranteeing that I won't have many transactions stuck, and guaranteeing the resulset (of the query) won't have uncommited data.

Any Suggestion ?
