Hi,
I would like to implement a 1:n relation between two
tables.
An auto-generated number should be used as primary key
which connects both tables.
Example:
table 1:
name | number (prim_key)
table 2:
country | number_table1 (foreign key)
View:
number_table1 | name | country
I would like to insert into both tables in one step.
"Insert into view (name,
country)values('name','country');"
Oracle supports an instead-of-trigger but Postgres
doesn't do this.
CREATE or replace FUNCTION insertInto() RETURNS
trigger AS ' BEGIN insert into table1(name)values(NEW.name); insert into
table2(number,country)values(NEW.number,NEW.country); RETURN NEW; END;
' LANGUAGE plpgsql;
CREATE TRIGGER insert_TR BEFORE INSERT OR UPDATE ON
view FOR EACH ROW EXECUTE PROCEDURE insertInto();
I would like to implement something like this but I
don't know how to do.
Thank you for you help!
Jakob
