EXECUTE INTO on 8.2
I'm seeing some strange behavior with the following code. It compiles and
runs but returns an error on the Execute statement:
List index out of bounds(0)
DECLARE
srec record;
v_formula varchar;
v_result varchar;
BEGIN
v_formula = 'select 4 as val';
EXECUTE v_formula INTO srec;
END;
However, the old school version runs w/no problem:
BEGIN
v_formula = 'select 4 as val';
FOR srec IN EXECUTE v_formula LOOP
v_result = srec.val;
END LOOP;
END;
Any idea why the new syntax isn't working? (I'm running 8.2 on a Windows
dev box.)

Worksforme. Want to provide a complete example instead of a fragmentary
one?
regression$# create or replace function foo() returns int as $$
declare srec record;
v_formula varchar;
v_result varchar;
BEGIN
v_formula = 'select 4 as val';
EXECUTE v_formula INTO srec;
return srec.val;
end $$ language plpgsql;
CREATE FUNCTION
regression=# select foo();
foo
-----
4
(1 row)
regression=#
