DBI::fetchall_arrayref returns an array of arrays. You need two indexes to dereference a data element. Let your code read, 

if ( $data->[0][1] eq "large" ) {    #something like this or...
   $data->[0][1] = uc ( $data->[0][1] );
}

Note that ucase is spelled uc, and does not modify its argument in-place.
