Thank you!
May be I have to try something like:

   FORALL e IN 1..1000 -- bulk-bind first part of varray

     DELETE PUSH_LIST_DELIVERY
     WHERE ID_MSG_LIST=t_ID_MSG_LIST(e);

   FORALL e IN 1001..cont_tot -- bulk-bind the rest of varray
     DELETE PUSH_LIST_DELIVERY
     WHERE ID_MSG_LIST=t_ID_MSG_LIST(e);


But I have to control the number of recors returned, so for example, if it's 3000, then it should be:

   FORALL e IN 1..1000

     DELETE PUSH_LIST_DELIVERY
     WHERE ID_MSG_LIST=t_ID_MSG_LIST(e);

  FORALL e IN 1001..2000
     DELETE PUSH_LIST_DELIVERY
     WHERE ID_MSG_LIST=t_ID_MSG_LIST(e);

   FORALL e IN 2001..cont_tot -- bulk-bind the rest of varray
     DELETE PUSH_LIST_DELIVERY
     WHERE ID_MSG_LIST=t_ID_MSG_LIST(e);

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=t_ID_MSG_LIST(e);

then

   ...
   FORALL e IN 1001..2000 -- bulk-bind second part of varray

     DELETE PUSH_LIST_DELIVERY
     WHERE ID_MSG_LIST=t_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
