Thread: dropping partitioned table waits forever

dropping partitioned table waits forever

Hi

 

I have a table partitioned on a daily basis. Data is constantly inserted in this table. When I attempt to drop a partition that is not used(i.e previous day’s), the drop table waits for a loooong time.This is probably due to the fact that the old partitioned table is being referenced in a query plan(the insert into the parent table uses triggers).

 

How can I prevent the locking out of the drop table? I tried truncate table but it is worse. It locks out the inserts in the parent table and then it waits.(hence causing a deadlock)

What about dropping/changing the trigger?
