Invalid Table Name error in EXECUTE IMMEDIATE

Question

Hi there.
I am trying to truncate few debug tables I created a used ago. Refer the code
declare
lv_sql varchar2(100) := 'truncate table :b1';
begin
for i in (select object_name
             from all_objects
            where object_type = 'TABLE'
              and object_name like 'DEBUG_%'
              and owner = user)
loop             
   dbms_output.put_line('Table Name: '||i.object_name);
   execute immediate lv_sql using i.object_name;
end loop;
end;Seems to be correct (unless I messed something big). And, I get an error message:
ORA-00903: invalid table name
ORA-06512: at line 13Any idea? Thanks in advance.

you can't bind table or column names... try this instead:
declare lv_sql varchar2(100);
begin for i in (select object_name
              from all_objects
            where object_type = 'TABLE'
              and object_name like 'DEBUG_%'
              and owner = user) loop
                 dbms_output.put_line('Table Name: '||i.object_name);
   lv_sql := 'truncate table '||i.object_name;
   execute immediate lv_sql;
end loop;
