Subj:   Confused By Block
 
From:   Hassinger, Bill

We have a user using an Alter Table to drop a column. It is a 300 Million row table. It appears that this statement is blocking all other queries on the system. Session Info shows that the other users are blocked because user 1 has a write lock on DBC.Accessrights for the duration of the query.

Why does the Alter Table have a write lock on DBC.AccessRights for more then seconds?

Is there a way around this lock? Locking for access does not seem to work.

Will killing this query cause a long rollback?
