parameters in functions and overlap with names of columns

I've

create or replace function(...

declare
  col1 varchar(32);
...

  create table pippo(
    col1 varchar(32),
...

Unfortunately I can't schema specify the column to avoid name
overlap.

Is there another way other than just simply rename the variable?

thanks
