Hello,
I have a table called X
it contains 3 fields of importance(amongst others).
time (timestamp), snooze (int) , inbox (int)

The time column sometimes has null values.
What I want is that every time a row is selected, if the time is a
null value, it is set to now() and snooze is set to 0 and inbox to 1

How would I go about doing this. I looked into Creating Rules, but I
am not sure if this will work.

Please Advice. Much thanks in advance.
