Dear Monks

I've used the prepare statement (with placeholders) so I can call the execute sub now like
   $sth->execute(@cols) ;

In which @cols is the array with a value for each placeholder.
However, I think I noticed a problem. What if I would like to set a column to 'NULL' (not a string!!!).
I've tried a couple of possibilities, like 
   $cols[0] = undef ;  # gives default value of that column 
   $cols[1] = 'NULL' ; # interpreted as string...

[download]
....
How should I solve this ? did I miss something obvious ?

Thanks a lot
Luca
