Hi,
It seems like a too obvious omission to not be intentional. But I wonder why a 
query like

SELECT SUM(A)
FROM TABLE
GROUP BY B
HAVING A <> 0

Is not rejected. MS SQL server gives you this error message in this case:

Column ?A? is invalid in the HAVING clause because it is not contained in 
either an aggregate function or the GROUP BY clause.

It's not even clear to me what SQLite does with a query like that.
