Reference Manual says that WHEN clause has no meaning in releases prior
to 10.11:

I get the same behavior. I will give it a try on earlier releases and
report the results

Hello,
In the below example, I expect trigger to fire and update the
'done_date' column after update of 'status', but it doesn't. The
database is a freshly created 10.11. Is this a bug in derby, or am I
doing something wrong?
ij version 10.11
ij> connect 'jdbc:derby:MyDbTest;create=true';
ij> CREATE TABLE t1 (id INTEGER, done_date DATE, status CHAR(1));
0 rows inserted/updated/deleted
ij> CREATE TRIGGER tr1 AFTER UPDATE OF status ON t1 REFERENCING NEW
AS newrow FOR EACH ROW WHEN (newrow.status='d') UPDATE t1 SET
done_date=current_date WHERE id=newrow.id <http://newrow.id>;
0 rows inserted/updated/deleted
ij> insert into t1 values (1, null, 'a');
1 row inserted/updated/deleted
ij> SELECT * FROM t1;
ID |DONE_DATE |STA&
---------------------------
1 |NULL |a
1 row selected
ij> UPDATE t1 SET status='d';
1 row inserted/updated/deleted
ij> SELECT * FROM t1;
ID |DONE_DATE |STA&
---------------------------
1 |NULL |d
1 row selected
ij> exit;
