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
