In addition to the reason for your error, which someone else has pointed out, this piece of code has another problem -- you never close your cursor. This will get you into no ends of trouble at some point in the future, so I though I should point it out. Also, a cursor for loop would be much cleaner, and you won't have to worry about closing the cursor. Like the following...

declare

     cursor c1 is
          select nm_enum_data
          from t_enum_data
          where id_enum_data in
               (select distinct id_view from t_acc_usage_1
               union
               select distinct id_view from t_acc_usage_2
               union
               select distinct id_view from t_acc_usage_3
          );
     --enum t_enum_data.nm_enum_data%type;    Don't need this variable

declaration any more
begin

     dbms_output.enable(900000);   -- This can be a value up to 999999
     for enumRec in c1 loop
          dbms_output.put_line(enumRec.nm_enum_data);
     end loop;

end;

Hi,

i am running following code

declare
cursor c1 is
select nm_enum_data from t_enum_data where id_enum_data in
(select distinct id_view from t_acc_usage_1
union
select distinct id_view from t_acc_usage_2 union
select distinct id_view from t_acc_usage_3 );
enum t_enum_data.nm_enum_data%type;
begin
open c1;
loop
fetch c1 into enum;
exit when c1%notfound;
dbms_output.put_line(enum);
end loop;
end;
/

i am getting error:
declare
*
ERROR at line 1:

ORA-20000: ORU-10027: buffer overflow, limit of 2000 bytes
ORA-06512: at "SYS.DBMS_OUTPUT", line 91
ORA-06512: at "SYS.DBMS_OUTPUT", line 58
ORA-06512: at line 16

What might be the reason????????

Thanks
Harvinder
