INSERT TRIGGER

Hello, once again today I´m searching for help :-/ I need to create an INSERT-TRIGGER. CREATE TRIGGER t1INSERT ON test REFERENCING OLD AS pre NEW AS post FOR EACH ROW WHEN (test.nr = 1) (INSERT INTO test2 VALUES (1)); I want to add a row (with value=1) to the table test2 everytime a new row with nr=1 in table test is added. The error message tells me "Incorrect use of old or new values correlation name inside trigger." In the manual I read: [...] You cannot specify an old correlation name for an insert trigger. You cannot specify a new correlation name for a delete trigger. [...] But how can I make a condition an the "OLD" table ?? Thanks for your patience Regards, Stephan
