Hi Dimitre,

The "limit" is associated with the "bulk collect".

If you try this out, change your syntax (below) around a bit.

The "bulk collect" would be placed inside your "forall" (since your
forall is your iteration scheme, as it were.)

Personally, I haven't tried placing a bulk collect inside a forall,
however, you *can* control the number of collection indices that you
iterate through with a forall.

Using this technique, you may be able to break up your forall into
chunks without having to  include a bulk collect clause.

For example:

   ...
   FORALL e IN 1..1000  -- bulk-bind first part of varray
     DELETE PUSH_LIST_DELIVERY
     WHERE ID_MSG_LIST=3Dt_ID_MSG_LIST(e);

then

   ...
   FORALL e IN 1001..2000  -- bulk-bind second part of varray
     DELETE PUSH_LIST_DELIVERY
     WHERE ID_MSG_LIST=3Dt_ID_MSG_LIST(e);

and so on.  The indices interated over in your FORALL statement will
match the index values in your collection, t_id_msg_list.

HTH,
Melanie
