Mike,
I posted this RULE also on hackers
CREATE or replace RULE crypto_view_delete_rule
AS ON DELETE
TO crypto_view
DO INSTEAD
(
select func_delFromCrypto( OLD.id,OLD.crypted_content);
);

Hello there,
I have a View with a Delete rule and I would like the Delete rule to call a
function (and pass-in a few of the the underlying View's/Table's column
values). How do you do this?
When I do it, I keep getting the following error:
ERROR: function expression in FROM may not refer to ot

I figured it out:
Here's how to get an ID from the table below, based on input crypto data
(this essentially is the reverse of Jim's excellent cryto-to-ID solution
below):

Jim,
I was thinking... In your excellent solution below, we select/decrypt and
return the crypto column based on an input Integer ID. This is good. But
what if we wanted to do the reverse?
That is, what if I want to select an ID based on input crypto data?
i.e., given my original table data

I would change the return type to TEXT, I believe your original example had it
as a varchar and I didn't change it.
Also, I believe that "under the hood" text does equal varchar.
Glad I could help

Thank you, Jim. You rock!
This worked although I'm a bit confused:
Your function below says it returns VARCHAR, yet the variable that holds the
contents of my SELECT which we ultimately return is of type TEXT.
When I return the TEXT variable, it works. Does this mean TEXT = VARCHAR in

Hello there,
What's the preferred and most efficient way to obtain PGCrypto encrypted
data from a plpgsql function?
1. Imagine the following simple table:
CREATE TABLE crypto (
pid SERIAL PRIMARY KEY,
title VARCHAR(50),
crypted_content BYTEA
);
2. Now insert the following 3 rows
Sometimes using a temp table is a better idea:
e.g.
-- start by creating a temp table 'tids' that hold the to_ids that
-- we are interested in.
SELECT to_id
INTO TEMP TABLE tids
FROM correlation
WHERE from_id = 1234
ORDER BY val DESC limit 100;
-- The following temp table makes use of t
