hi

use thsi to calculate the size of long raw.

set serveroutput on

declare
length_var NUMBER;
cursor toy_cursor is
select * from TOY;
toy_val toy_cursor%ROWTYPE;
begin
open toy_cursor;
fetch toy_cursor into toy_val;
length_var := LENGTH(toy_val.Description);
DBMS_OUTPUT.PUT_LINE('Length of Description: '||length_var);
close toy_cursor;
end;

toy_val.Description is a column of long raw okay

regards
