I am trying to write a function that updates the
date column to the current date. According to:
http://www.postgresql.org/docs/8.4/static/functions-datetime.html#FUNCTIONS-DATETIME-CURRENT
you can use CURRENT_DATE. When I try to use it in
the following pl/pgSQL function it gives the error:
ERROR: date/time value "current" is no longer supported
CONTEXT: PL/pgSQL function "merge_data" line 4 at assignment
Here is the code I am using:
CREATE FUNCTION merge_data(key INT, i INT) RETURNS
VOID AS
$$
DECLARE curtime date;
BEGIN curtime := 'CURRENT_DATE'; LOOP -- first try to update the key UPDATE data SET count = i, date =
curtimeWHERE k = key; IF found THEN RETURN; END IF; -- not there, so try to insert the key
-- if someone else inserts the same key concurrently, -- we could get a unique-key failure BEGIN
INSERT INTO data(k, count, date) VALUES (key, i, curtime); RETURN; EXCEPTION WHEN unique_violation
THEN -- do nothing, and loop to try the UPDATE again END; END LOOP;
END;
$$
LANGUAGE plpgsql;
It looks like it is keying on the CURRENT and dropping the _DATE piece.
I suspect that I am doing something wrong but I am not able to find a
pointer in the docs or mailing lists. Any help would be greatly appreciated.

Ken
