Lock a table until Package execution finishes

Hello,
I need to lock a table in startup of my package so that access calls from other applications are put on "wait" by sql server until I unlock.

Any idea how would I do it ?
Or is it possible or not ?

Thanks,
FahadIf you use MS Access database I think it will be locked automatically.|||You may want to jump over to the Transact-SQL forum to get help on this. I would imagine you can issue a table lock command in an Execute SQL task, and then when done processing release that lock in another Execute SQL task.
