Hi Roland,

Jus change the after trigger to before and the code works!!..

logically after insret is used to replicate data and not for data cleansing . When data cleansing is required use before insert trigger( before the data is actually inserted)

Cheers
Roopesh

Subject: Trigger question

Hallo,

What is wrong with this trigger:

I want the trigger to fire(to run the statement : UPPER(SUBSTR(:OLD.namn, 1, 1)) || SUBSTR(:OLD.namn,2); after new record is inserted in this table.

The thing to happen should be this:

I want that script to be run on the same record that has been inserted in the table. So the UPPer command should run on the namn field that has been inserted in the table. Hope anyone can´help me.

CREATE OR REPLACE TRIGGER AFTER_INSERT_ROWins_ON_test after insert

      ON test
     REFERENCING NEW AS NEW OLD AS OLD
     FOR EACH ROW

BEGIN :NEW.namn :=UPPER(SUBSTR(:OLD.namn, 1, 1)) || SUBSTR(:OLD.namn,2);

:NEW.namn := UPPER(SUBSTR(:OLD.namn, 1, 1) || SUBSTR(:OLD.namn), 2); EXCEPTION WHEN OTHERS THEN raise_application_error(-20000, 'ERROR IN TRIGGER AFTER_INSERT_ROWins_ON_test: ' || SQLERRM);

END; /

Thanks in advance

Roland S
