Sorry, I should have RTFM(!!!). I found it under 4.2.4 Field selection. Apparently it works just as I want, but I should have put parenthesis around the row-name like this:
> select result,(resulting_row).name from verify_record(1234);
name | result
-------|--------
"Test" | "OK"
I also discovered you can do a
> select result,(resulting_row).* from verify_record(1234);
to combine the both results to a single returning row if needed... sweet!

Hi,i'm defining a function in plpqsql and would like it to return one varchar and one row from another table. I have defined it like this (this is only a test and does not really make sense yet, but it's the principle i'm after):CREATE OR REPLACE FUNCTION verify_record(IN number_to_verify bigint, OUT resulting_row logbook, OUT result character varying)
RETURNS record AS
$BODY$
BEGIN
SELECT * INTO resulting_row FROM logbook WHERE id_number=number_to_verify::varchar;
SELECT 'OK' INTO result;
END
$BODY$
LANGUAGE 'plpgsql' VOLATILE SECURITY DEFINER
COST 100;It works fine and i can do a select like this:> select * from verify_record(1234);resulting_row | result------------------------------|--------(1,"Test","Registered",.....) | "OK"So far so good, but how do I use the the resulting_row further, say if i would like to select only a few columns or perhaps define a view that returns the 'result' column and only column 2 "Test" from the resulting_row?What I'd like to do is a select and sub-address the individual columns of the resulting_row, like writing (given 'name' is the name of some column in resulting_row):> select returned_row.name, result from verify_record(1234);or perhaps> select returned_row['name'], result from verify_record(1234);and have it return something like:name | result-------|--------"Test" | "OK"Is this possible or am I on the wrong track here?//Kenneth
