Re: [CDBI] How do I add a method to a loaded class?

> =20

The columns method with no arguments returns 'ALL' columns.  This
strangely does not return TEMP columns  in .96  (probably for good
reason though).  Maybe this has changed in .99.  Read the docs but im
guessing if you want TEMP columns to be lumped with ALL columns you
will have to call them explicitly . Try something like

my @all Unless it has been changed in .99,=20
