Hmm that looks cleaner but gives me an error...
I left out the indexing for simplicity...
v= 123
periods= [:day, :week, :month, :year, :alltime]
DB[:stats].update_sql(periods.inject({}){|h, p| h[p] = p + v})
= NoMethodError: undefined method `[]=' for

Point taken, I've been bitten by that inject typo many times, and
still make the same mistake!!
Maybe I'll remove inject from my repertoire ;)

Ummm is there an alternative to the .update{ } syntax? which also
seems to have been deprecated? If there is it is not documented. (and
I use it extensively in my scripts).
Thanks

How do you use this? Using == for assignment feels weird:
DB[:table].update_sql{ :a == 1 and :b == 2 }
= UPDATE
I use it like this...
DB[:table].update{ :a :a + 1 }
- UPDATE table SET a = a + 1
(I never did like the syntax but it worked)
and I also use it to build up updates programatically there was a
thread on that
DB[:table].update{ :a :a + 1 }
- UPDATE table SET a = a + 1
These work:
DB[:table].update_sql( :a = (:a+1) )
= UPDATE `table` SET `a` = (`a` + 1)
DB[:table].update_sql( :a = 'a+1'.lit )
= UPDATE `table` SET `a` = a+1

Hi,
Perhaps my understanding is stale/wrong.
Parse-tree was removed since it used s-expressions and these aren't
available in some of the newer Ruby VM's.
A downside of this was losing Sequel filters.
I'm not Parse-tree guru so perhaps someone can comment on whether
cry could be an
