Need ouput more than 4000 characters

Question

Hi , how to create a script that fetches more than 4000 charaters in the ouput

Answer 1

declare your pl/sql variable as varchar2(32767) which is the maximum and then you can select that amount.Not so fast Blu ;)
SQL>  create or replace function f
return varchar2
as
begin
return lpad ('x', 32767, 'x');
end f;
Function created.
SQL>  exec dbms_output.put_line(length(f))
32767
PL/SQL procedure successfully completed.
SQL>  select length (f) from dual
select length (f) from dual
Error at line 1
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "MICHAEL.F", line 5To SELECT more than 4000 chars you'll always need a CLOB ..
