I have the following query:

	SELECT cast( sum(amount) AS NUMERIC(9,2) ) ... 
	WHERE postdate < $startdate 

(where $startdate is replaced with the user's entry at runtime) which returns
the balance forward of the amount column for the user-suplied date correcly
unless the user supplies a $startdate such that no culumns are being added.
In this case NULL is returned. I want to receive 0.00 in this case instead of
NULL, so I added the cast above, but NULL is still returned. Any ideas?
