Oracle - ORA-06502: PL/SQL: numeric or value error (DBMS_OUTPUT)

Question

I implemented a function that returns clob data-type, and I would like to print the result in DBMS Output. Unfortunately, I am getting

Answer 1

The following procedure will better:

• Oracle 10g has limitation on put_line (a maximum of 32767 characters), But Oracle before 10g has a maximum of 255 characters limitation.
• the 'put_line' adding end of line on every iteration loop during output clob. So we use put() better (and 'DBMS_OUTPUT.NEW_LINE' at end).

    PROCEDURE print_clob( p_clob in clob ) IS
        v_offset number default 1;
        v_chunk_size number := 255; 
      BEGIN
        LOOP
          EXIT when v_offset > dbms_lob.getlength(p_clob);
          dbms_output.put( dbms_lob.substr( p_clob, v_chunk_size, v_offset ) );
          v_offset := v_offset +  v_chunk_size;
        END LOOP;
        DBMS_OUTPUT.NEW_LINE;  
      END print_clob;
