I don't think this is correct. WITH ROLLBACK AFTER | IMMEDIATE specifies when any [B]other[/B] transactions in the database should be rolled back, eg when setting the db to single user mode. NO_WAIT specifies that if the ALTER DATABASE command cannot complete, ie other open transactions exist, then the ALTER command itself should rollback/fail. The NO_WAIT command has the same effect as ROLLBACK IMMEDIATE.
