Thread: arhiving rule

I have, what I think is a simple rule to arrive transactions:
create rule usageupdt as on update to usage          do insert into usageHistory             (lkey, jan, feb, mar,
bowner,penalty, prepay, bal, notes,
 
change)          values             (new.lkey, old.jan, old.feb, old.mar, old.bowner,              old.penalty,
old.prepay,old.bal, old.notes, 'now')
 


the only problem is that once is rule is created,  new rows in the
archive table all have the same date!        -the date when the rule was created....

   thanks   art

Try now() instead of 'now'.  The latter is coerced to a timestamp
constant as soon as the rule is parsed ...
