thanks in advance

usually use such checking , if not exists doesnt work on oracle (as far know)

declare  cnt number(4); begin   select count(1) cnt             carp.table1             fk_tab1  =ps.id_tab1             , dic_type = compteur    if cnt = 0 insert               carp.table1                 (                   id,                   fk_tab1,                   dic_type                 )                 values                 (                   id.nextval ,                   ps.id_tab1 ,                   compteur                  )  end if;     end; / commit /
