It depends on the size of the table and the frequency of updates, deletes
but cold consider an audit table with triggers for update, delete and
truncate. At least you have a way to recover deleted records.

Hello Laurenz,
Thank you for you suggestion. I really want to aviod that someone
'accidentally' deletes too much by typing (programming) a not full qualified
DELETE ... statement. In your case one would have to always use the delete
function, but no restrictions on using the DELETE statem

Hi,
I am running PostgreSQL 9.3.4. I have a simple table with 3 fields:
CREATE TABLE devicegroup (
groupid integer NOT NULL,
ctrlid integer NOT NULL,
userid integer NOT NULL
);
ALTER TABLE ONLY devicegroup
ADD CONSTRAINT pk_devicegroup PRIMARY KEY (groupid, ctrlid, userid);

You can't return NEW in an ON DELETE trigger - there is no NEW record.
Since you're going with a STATE
Thank you very much, that answers my question.
And yes, I think you are right with the FOR EACH ROW/STATEMENT, I didn't
think that through for this example.
Thank you for your help!

Hello everyone,
I have this question regarding delete triggers and how it affects data
integrity.
So here goes: I have this trigger which deletes everything before I insert
new rows.
CREATE OR REPLACE FUNCTION delete_records()
RETURNS TRIGGER AS $$
BEGIN
delete from "TABLE";
RETU

There's no "NEW" row in a delete trigger (... and the error message
s
When I update, insert or delete to one table, I need a trigger to delete and
possibly insert into another table. The trigger I have works for insert and
update, but returns an error when I do a delete.
The is no explicit link between the tables, so I can't do 'DELETE CASCADE'
or anything like that
How do I get the values of parameters in the query?
e.g.
where x = 'op';
i.e. How do I get ?
field: x
value : op
any example, pointers will help.
thanks,
