Multi Row DELETEs

[Quoted] Multi-row DELETEs

I am trying to do something conceptually very simple.

I have 2 tables. I want to delete the records in one table, that don't exist in the other table.

Initial queries are:

Select c.agt_ref
from agt3 c, agt b
where c.agt_ref = b.agt_ref (+)
and b.agt_ref is null

37 rows selected. Elapsed: 00:00:00.74

select c.agt_ref
from agt3 c
minus
select a.agt_ref
from agt a

37 rows selected. Elapsed: 00:00:00.77

You would figure that deleting these records would be very simple. Yet, nothing works.

delete from AGT
where AGT_REF IN
(select c.agt_ref

from agt3 c
minus
select a.agt_ref
from agt a )

0 rows deleted. Elapsed: 00:00:00.72

Delete from AGT
where AGT_REF IN
(select c.agt_ref

from agt3 c, agt b
where c.agt_ref = b.agt_ref (+)
and b.agt_ref is null )

0 rows deleted. Elapsed: 00:00:00.80

[Quoted] I DO have DELETE privileges on the AGT table.

[Quoted] Am I missing something? Any ideas?
