Обсуждение: plpgsql/cursor

can i declare and fetch from a cursor inside a plpgsql function?  (pg
version 7.0.3)

if so, what would the syntax look like?  i continue to get parse errors on
'cursor' in a very, very simple test.

thanks

In 7.1, the pl/pgsql document says you can code like
this:

DECLARE
 rec record;
BEGIN
 for rec in SELECT * from MyTable LOOP
    update tableX set tableX=rec.fieldA;
 END LOOP;
END;

    Refernce cursors will occur in PostgreSQL v7.2. Not sure when
    it'll be finally released yet.
