I've used triggers before in another DB where the total functionality
was included in the CREATE TRIGGER statement, totally written in SQL. I
understand that postgresql can't do that (correct?).
I want to delete a row in table 2 when I update table 1, with something
along the lines of :
CREATE TRIGGER mytrigger AFTER UPDATE ON table1
FOR EACH ROW
DELETE FROM table2
WHERE table1.id = table2.id
Afterwards I will re-insert any necessary info into table 2.
Can anyone help me with this?
TIA
ps If I need to use a function to do this, pls show me how to do the
same with a function.
