Hello
Every SELECT statement in PL/pgSQL have to be forward to variables. In
plpgsql you can you use select only like
select into variables columns from ...
propably better version is (i haven't installed dblink and can't to test it)
CREATE OR REPLACE FUNCTION GetReminderServices( varchar ) RETURNS
SETOF reminder_services AS'
DECLARE r record;
BEGIN
PERFORM dblink_connect(''dbname=''||$1);
FOR r IN SELECT * FROM dblink(''SELECT * FROM reminder_services'')
AS reminder_services( uid INT,
theme_uid INT,
activity_MT_amount INT,
activity_min_days INT,
activity_max_months INT,
inactivity_days INT,
limit_reminders INT,
limit_months INT,
scanning_time TIMESTAMP WITH TIME ZONE,
reminder_time TIMESTAMP WITH TIME ZONE,
message TEXT)
LOOP
RETURN NEXT r;
END LOOP;
PERFORM dblink_disconnect($1);
RETURN
END;
' LANGUAGE plpgsql;

2007/7/3, Loredana Curugiu <[EMAIL PROTECTED]>:
Hi everybody,
I created the following function:
CREATE OR REPLACE FUNCTION GetReminderServices( varchar ) RETURNS SETOF
reminder_services AS'
BEGIN
SELECT dblink_connect(''dbname=''||$1);
SELECT * FROM dblink(''SELECT * FROM reminder_services'')
AS reminder_services( uid INT,
theme_uid INT,
activity_MT_amount
INT,
activity_min_days
INT,
activity_max_months
INT,
inactivity_days INT,
limit_reminders INT,
limit_months INT,
scanning_time
TIMESTAMP WITH TIME ZONE,
reminder_time
TIMESTAMP WITH TIME ZONE,
message TEXT);
SELECT dblink_disconnect($1);
RETURN;
END;
' LANGUAGE plpgsql;
When I call this function as SELECT * FROM GetReminderServices('eu');
I get the following errors:
ERROR: query has no destination for result data
HINT: If you want to discard the results of a SELECT, use PERFORM instead.
CONTEXT: PL/pgSQL function "getreminderservices" line 2 at SQL statement
Does somebody know which is the problem?
Best,
Loredana
