In PL/pgSQL - SQL Procedural Language, 37.6.2. SELECT
INTO, is written:
Here is an example that handles the case where no rows
have been returned:
DECLARE
users_rec RECORD;
full_name varchar;
BEGIN
SELECT INTO users_rec * FROM users WHERE
user_id=3;
IF users_rec.homepage IS NULL THEN
-- user entered no homepage, return "http://"
RETURN ''http://'';
END IF;
END;
In the example before this no rows were returned. This
is an example of NULL result, not of NOT FOUND. The
comment says "-- user entered no homepage".
In "37.8.3.3. Returning Cursors" is written:
<unnamed cursor 1>
But I'm getting;
<unnamed portal 1>
