RE: Avoding Mutation of Table triggerHi 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
