我正在尝试编写一个在执行插入时执行的触发器函数。条件是,如果 id 已经存在,那么 time_create 现在应该是 time_dead。
CREATE function archive_temp() returns trigger as '
begin
insert into temporary_archive
values
(
OLD.id,
OLD.time_create,
OLD.time_dead,
OLD.fname,
current_user,
now(),
now(),
TG_OP
);
return null;
end;
' LANGUAGE 'plpgsql';
-----------------------------
CREATE TRIGGER archive_temps
AFTER DELETE OR UPDATE
on temporary_object
FOR EACH ROW
DECLARE
temporary_archive temporary_object.id%type;
begin
if inserting then
select id into temporary_archive
from temporary_object
where id = :old.id;
if temporary_archive is not null then
EXECUTE PROCEDURE archive_temps();
end if;
end if;ins
