How to put_line a big buffer ?

Question

I am constructing a select query in a stored procedure, depending on different cases . At the end I am executing that select query. This select query is buffered in a VARCHAR2(8000) buffer.
I want to output a this buffer, which is in fact a select query, just before the execution.
Here is my Code
dbms_output.enable(1000000);
DBMS_OUTPUT.PUT_LINE ('STATEMENT *** ' );
DBMS_OUTPUT.PUT_LINE (STATEMENT); -- Note that STATEMENT is my buffer name
OutpUt is as :
STATEMENT ***
Parse error: -20000 at position 0
i.e the word "STATEMENT ***" is displayed properly in dbms_output . My procedure also executes fine. However I am getting error as "Parse error: -20000 at position 0".
I am using TOAD 9.0.1.8 and oracle 9.
How can I get the complete sql constructed.

Answer 1

dbms_output has a limit of 255 characters per line
the complete error is
ERROR at line 1:
ORA-20000: ORU-10028: line length overflow, limit of 255 chars per line
ORA-06512: at "SYS.DBMS_OUTPUT", line 35
ORA-06512: at "SYS.DBMS_OUTPUT", line 115
ORA-06512: at line 1something (your pl/sql around the code, or toad) is suppressing the error message.
for i in 1 .. ceil(length(statement)/255) loop
dbms_output.put_line( substr( statement, (i-1)*255, 255) );
end loop;
