I have 2 tables which are my_school and my_class
And "my_school" table has 'info_id' column and also "my_class" table has 'info_id' then I want to get a query that automatically generate "info_id" then I found solution..
Here are my working TRIGGER on "my_school" table...
--------------------------------------------------------------
CREATE OR REPLACE TRIGGER info_id
before insert on my_direction
for each row
begin
if :NEW.WAY_ID is null then
:NEW.WAY_ID := example_id_seq.nextval;
end if;
end;
/
--------------------------------------------------------------
It works and it's generating auto id when inserting value. But now how to get this trigger when users insert value then take id with my_school's "info_id" same time?
