Many thanks to Stephan, Richard and George. When I was reading the
documentation about FOR loops, I didn't realize that I was in the plpgsql
section!
CREATE OR REPLACE FUNCTION rgio() RETURNS integer as $$
BEGIN
DECLARE lv RECORD;
FOR lv IN SELECT DISTINCT rg FROM ldevrg LOOP
SELECT ldev FROM ldevrg WHERE ldevrg='$lv';
END LOOP;
RETURN 1;
END;
$$ LANGUAGE plpgsql;
So I've made progress, but I'm running into the same thing.
psql:rgio.sql:16: ERROR: syntax error at or near "FOR" at character 86
psql:rgio.sql:16: LINE 6: FOR lv IN SELECT DISTINCT rg FROM ldevrg LOOP
psql:rgio.sql:16: ^
If I comment out the DECLARE statement above, I get the following:
psql:rgio.sql:16: ERROR: loop variable of loop over rows must be record or row
variable at or near "LOOP" at character 129
psql:rgio.sql:16: LINE 6: FOR lv IN SELECT DISTINCT rg FROM ldevrg LOOP
psql:rgio.sql:16:
^
Ideas?

Subject: [SQL] Error when trying to use a FOR loop
Sorry if this is in the archives, but I've done a search and couldn't find
anything relevant. I'm running HP's precompiled version of 8.1.3.1 as part of
their Internet Express offering, and I can't seem to run a for loop. Here's
what I'm seeing:
xp512-0715-0716=# FOR LV in 1..10 LOOP
xp512-0715-0716-# select * from ldevrg;
ERROR: syntax error at or near "FOR" at character 1
LINE 1: FOR LV in 1..10 LOOP
^
I'm still pretty new to postgres, but based on the documentation I'm not
picking up what I'm doing wrong.
Help much appreciated.
Thanks,
Kevin
