Oracle Trigger - display debug information

Just for my own reference:

(1) within trigger use DBMS_OUTPUT.PUT_LINE, e.g.

 DBMS_OUTPUT.PUT_LINE(REC_INSP.FID || ' ' || REC_INSP.FID_BAUM);  

to display text in SQL Developer:

(2a) - open DBMS output panel 
(2b) - in DBMS-output panel : choose active Oracle connection

or:

(3) - run:

 SET SERVEROUTPUT ON  




(4) execute SQL in SQL Developer which fires trigger


>> Debug information will be displayed either in DBMS-output or Script output panel

SQL Developer - DBMS output panel
