Thread: Possible to access value in RECORD without knowing column name?

In plpgsl, if I have a RECORD variable that is populated via some
dynamic SQL, is it possible to access the columns in that RECORD
object without knowing the column names?  I.e. Can I grab whatever
value is the 3rd column?

random_colname = 'foobar';
sql = 'SELECT col1, col2, ' || random_colname || ' FROM table';

FOR mviews IN EXECUTE sql LOOP  --possible to access 3rd column of mviews?  something like mviews[3]?
END LOOP;

Regards,
Collin

my_column = 'foo'
sql = 'select col1, col2, ' || my_column || ' as bar from mytable;
for myrecord in execute sql
loopmyvariable = myrecord.bar
end loop;
