Ok, it appears now I have an error.. Unless I'm going crazy, this started
after I had to do a restore because of one of those cache lookup errors.. I
changed nothing, still, this is what I get..
CREATE FUNCTION invoice_payment() RETURNS OPAQUE AS '
BEGIN
UPDATE invoice_master SET total = total - NEW.amount,updated = now(),
is_paid=(CASE WHEN (total - NEW.amount) = 0.00 THEN ''t'' ELSE ''f'' END)
WHERE invoice_id = NEW.invoice_id;
RETURN NEW;
END;
' LANGUAGE 'plpgsql';
Now I get
brw=# INSERT into invoice_payments VALUES
(1,1000,'now',100,'now',100,1,1,150.00);
ERROR: Unable to identify an operator '=' for types 'numeric' and 'float8'
You will have to retype this query using an explicit cast
DEBUG: Last error occured while executing PL/pgSQL function invoice_payment
DEBUG: line 2 at SQL statement
ERROR: Unable to identify an operator '=' for types 'numeric' and 'float8'
You will have to retype this query using an explicit cast
brw=#
--- amount and total are both numeric(9,2), I've tried casting everything
(total,amount and 0.00) to float and everything to numeric with the same
error popping up.. What needs casting here?
I can determine if an invoice has been paid or not a number of ways, really
what I should do there is NEW.amount >= total -- I tried and got the above
error again..
Thanks!
