PL/SQL: FOR r IN (SELECT ... INTO ) ... Hmm?

Today, I came across a funny piece in some sort of legacy code that I think should not compile:

for r in ( select i, t into rec.i, rec.t -- Hmm??? from tq84_foo ) loop .... end loop;

My understanding is that the INTO clause should not be valid because the select statement is embeded in a FOR r IN (SELECT...) loop. Yet, it compiles, at least in Oracle 11i.

Here's a little test script for demonstration purposes:

create table tq84_foo ( i number, t varchar2(10) ); insert into tq84_foo values (1, 'abc'); insert into tq84_foo values (2, 'def'); declare rec tq84_foo%rowtype; begin for r in ( select i, t into rec.i, rec.t -- Hmm??? from tq84_foo ) loop dbms_output.put_line('rec: i= ' || rec.i || ', t=' || rec.t); end loop; end; / drop table tq84_foo purge;

The output is

rec: i= , t= rec: i= , t=
