I'm working with different functions and following an example of iterating
through rows from a returned query. It's not a complicated function, but I
can't get past this parse error. I've tried numerous things and searched
for some help. I can't find any reason for the error below:
ERROR: syntax error at or near "$1" at character 30
CONTEXT: PL/pgSQL function "list_devices" line 6 at for over select rows
Any help would be greatly appreciated!
Thanks,
Ryan
CREATE FUNCTION list_devices(macaddr) RETURNS text AS '
DECLARE
macAddress ALIAS FOR $1;
rowval record;
devices text;
BEGIN
devices := '' '';
FOR rowval IN SELECT device_type_id FROM devices WHERE mac_address =
macAddress LOOP
devices := devices || ''\r'';
END LOOP;
RETURN devices;
END;
' LANGUAGE 'plpgsql';
