Passing sequence number to queue table

Question

Hi anyone,
I am very new to the advance queue. Have a user_info table. I would like to pass the userid sequence to the queuence table up on insert or update on to the usere_info table.. Here is the step I did so far.
create type user_id as object(userid number, login varchar2(100));
execute dbms_aqadm.create_queue_table(queue_tale => 'user_fque_tab', queue_payload_type => 'user_id');
execute dbms_aqadm.create_queue(queue_name => 'user_que', queue_table => 'user_que');
execute dbms_aqadm.start_queue(queue_nama => 'user_que');
Now I am trying to create the trigger on the user_info table to pass the next sequence id to the queue table but not sure what to do.
so far I created on the trigger
create or replace trigger user_infor_queue after insert on user_info
for each row
declare
p_userid number;
enqueue_options dbms_aq.enquue_options_t;
message_properties dbms_aq.message_properties_t;
login varchar2(100);
v_message userdata.user_id;
begin
v_message:= userdata.user_id( p_userid =>new.id, login =>:new.login)
Please help on the creating the trigger...
thanks

Hi Bob,
In TestStand 3.0 and later you can pass the sequence context as a CAObjHandle in CVI. The easiest way to get an example of this is to create a blank sequence and insert an Action step. Right-click on the step and select specify module. On the module tab specify a name for the function. Next on the Source Code tab click Create Code... This will prompt you for a location and name for a project file and a c file. It will then create code for you that demonstrates how to pass the sequence context and use it.
If you're using an older version of TestStand then the parameters you can pass are fixed. I would suggest looking at one of the shipping examples. The Register step in the following example demonstates how to pass the sequence context and use it: C:
\Program Files\National Instruments\TestStand 3.1\Examples\Demo\C\cpu.seq
(This path will be different depending on your version of TestStand.)
I hope this helps!!
