oracle pl sql how to see dbms output put line

1By default, most tools do not configure a buffer for dbms_output 
2to write to and do not attempt to read from that buffer after code executes. 
3Most tools, on the other hand, have the ability to do so. In SQL*Plus, 
4you'd need to use the command set serveroutput on [size N|unlimited]. 
5
6So you'd do something like
7
8SQL> set serveroutput on size 30000;
9SQL> exec print_actor_quotes( <<some value>> )
10;
11In SQL Developer, you'd go to View | DBMS Output to enable the DBMS Output 
12window, then push the green plus icon to enable DBMS Output for a particular 
13session.

15Additionally, assuming that you don't want to print the literal 
16"a.firstNamea.lastName" for every row, you probably want
17
18FOR row IN quote_recs
19LOOP
20  DBMS_OUTPUT.PUT_LINE( row.firstName || ' ' || row.lastName );
21END LOOP;
