Hi Paul,
You Rocks !!!!!!!n Yes It is working as expected.
I would also like to know that if I need to learn Triggers and Stored
Procedures then what document should I refer, I am am new for triggers and SP.
Googling is random way I see. Would you refer any good books for this?
Corrected Trigger is as below:
SET TERM ^ ;CREATE TRIGGER MYTRIGGER FOR TABLE_NAME ACTIVE
BEFORE UPDATE POSITION 0
as
begin
if (new.col3 is distinct from old.col3)
then new.col5 = current_timestamp;
end^
SET TERM ; ^
Thanking You And With Best Regards.
Vishal

My fault! If forgot the trigger name. It should be:
create trigger MyTrigger before update on Table_Name ...
Instead of MyTrigger, you choose a more meaningful name of course.
