ORA-01704 error while running dbms_sql for a clob

Question

Hi,
I'm running following code and getiing error ORA-01704: string literal too long
declare
cursor_name INTEGER;
t1 clob;
t2 clob;
r number;
begin
select a1 into t1 from temp
where n1 = 'test';
t2 := 'insert into temp (a1,n1) values (''' || t1 || ''',''test12'')' ;
cursor_name := dbms_sql.open_cursor;
DBMS_SQL.PARSE(cursor_name, t2, DBMS_SQL.NATIVE);
r := DBMS_SQL.EXECUTE(cursor_name);
DBMS_SQL.CLOSE_CURSOR(cursor_name);
dbms_output.put_line(r);
end;
clob t1 is 32598 butes long.
in temp table a1 is a clob.
Could anyone please tell me why the error and how to solve the problem.
Thanks

This is one of the many posts over here where the OP can not be bothered to include the four digit version number.
I can never understand why the version number is left out other than out of rudeness, arrogance and utter laziness.
Apparently the small lot here responding should be clairvoyant and/or remember all version numbers.
I'm going to call for a boycot of people posting without version number!!!!
As to the code:
There is no reason why you are using dbms_sql here, you are misusing Oracle, and it should have been static sql.
At least t2 should have been a bind variable, dbms_sql does support bind variables!
As far as I know the command string should be a varchar2, not a clob, and if t2 is a bind variable there is no need for t1 to be a clob.
