If i issue a rollback when recovery mode is bulk logged, will my bulk operations be rolled back?
I decided asking here was just being ultra-lazy so tested it myself. 

create table tmp_insert_in_txn ( something int not null primary key ) 
begin transaction 
    select 1 as something into tmp_created_in_txn
    -- show the value was inserted
    select something as in_txn from tmp_created_in_txn

    insert into tmp_insert_in_txn  with ( tablock )
    (   something   )
    select something from tmp_created_in_txn    

    -- show the value was inserted
    select something as in_txn from tmp_insert_in_txn
rollback
-- no rows after rollback:
select * from tmp_insert_in_txn
-- no table after rollback:
select * from tmp_created_in_txn


This shows that the rollback does remove the table tmp_test and the row from tmp_test2, so the answer is that minimally logged operations are still rolled back.

Hmm... so how come using them prevents the transaction log from getting really big?
