Trigger problem

HI all,

I have 2 tables and 1 trigger,

So, if i do

insert into abreviations(smot,mot,abreviation,pays) select
smot,mot,abreviation,pays from a;

the Trigger is executed for each row ONLY after all rows have been
inserted, so the
"   id    := currval(''abr_id'');"
in my trigger have false value (always the last value after 53000 insert
...)

Any way to fire a trigger really when a row is inserted ?

thx

drop trigger TAB_PAYS ON abreviations;
