=item NULLABLE (array-ref) read-only
Returns a *reference* to an array indicating the possibility of each column
returning a null: 0 = no, 1 = yes.
Example:
print "First column may return NULL\n" if $sth->{NULLABLE}->[0];
=item CursorName (string) read-only
Returns the name of the cursor associated with the statement handle if
available.
=item Statement (string) read-only
Returns the statement string passed to the the prepare entry elsewhere in
this document method.
=item RowsInCache (integer) read-only, currently return undef.
If the driver supports a local row cache for select statements then this
