I have a view and update rule on it, which updates another table. Now I would like to call a function, after update of the table is done. Also the function must be called in the same transaction as update. I tried to define an additional update rule on the view, but doing a SELECT in update rule spoils the affected records count:
hekotek=# create table a(id integer); CREATE TABLE hekotek=# create view v as select * from a; CREATE VIEW hekotek=# create rule r as on update to v do instead update a set id = new.id where id = old.id; CREATE RULE hekotek=# create rule r1 as on update to v do select 1; CREATE RULE hekotek=# insert into a values (1); INSERT 1194985 1 hekotek=# update v set id = 2; ?column? ---------- 1 (1 row) hekotek=# drop rule r1 on v; DROP RULE hekotek=# update v set id = 3; UPDATE 1 It's important to me to have correct affected records count returned. I cannot use triggers, because views can't have triggers. I also cannot define the trigger on the table, because the function must be called only when updated through the view. I think I could define the rule to call the function in update query for some dummy table: update dummy set field = function(parameters). But is there a better way?
