Hi there,
I want to put a number of records (variable number
depending on a attribute of a table) into a certain
table with a trigger statement.
I have created the follwing trigger:
CREATE FUNCTION vullalles() RETURNS trigger AS '
BEGIN
FOR i in 0..7 LOOP
INSERT INTO lessons (select
dayofweek,startdate,endate,startime,endtime,teacher,location,roomnr
from courseschedule);
startdate := startdate + i*7;
EXECUTE startdate;
RETURN NEW;
END LOOP;
END;
' LANGUAGE plpgsql;
When I insert a record into courseschedule, I get the
following error:
insert has more expressions than target column
WHAT AM I DOING WRONG?
The function should insert 8 records into lessons when
I insert one record in courseschedule. Now it is done
with a hardcoded for loop but eventually it should be
done based on a attribute in courseschedule.
How can I fix this?
I'm using postgresql 7.4.3 under Freebsd.
