Naba,
I think you need something like this
CREATE OR REPLACE TRIGGER triggername
AFTER INSERT OR UPDATE OR DELETE
ON tablename
FOR EACH ROW
WHEN (NVL(new.fldname1,old.fldname1)is not null and
NVL(new.fldname2,old.fldname2)is not null)
DECLARE
BEGIN
processing goes here
END;
hth,
Chaim

Hi all,
I have row level table trigger to fire on DELETE or INSERT or UPDATE
Mode .
It has to fire on certain condition, meaning I have a WHEN condition also.
WHEN Condition is like :
when ( NEW.CR_ACCOUNT is not null and NEW.CHQ_DT is not null )
Since, in DELETE mode NEW value contains null , it does not fire.
This Problem would have solved if could write WHEN Condition as
when ((INSERTING or UPDATING) and NEW.CR_ACCOUNT is not null
and NEW.CHQ_DT is not null ) OR
(DELETING and OLD.CR_ACCOUNT is not null and OLD.CHQ_DT
is not null )
But in WHEN condition one can not write INSERTING or UPDATING.
How do i go about it ? Any round about way
Thanks & Regards.
Naba
