I created a UDF like a more complex version of this:
CREATE FUNCTION MTD(date, decimal(11,2)
RETURNS DECIMAL(13,2)
RETURNS NULL ON NULL INPUT
.
The select would like like:
SELECT TRNDATE, AMOUNT, MTD(AMOUNT)
ORDER BY TRNDATE
And ideally the result would be a running total of month-to-date values.
Pretty slick.
What I found, though, leads me to believe that the MTD function is being
called before the ORDER BY, and that's giving me wildly incorrect results,
even when the source table is already in that sequence. When the source
table is already in the correct sequence and I drop the ORDER BY, I
*seem*to* get the results that I want, but I doubt there's any guarantee of
that; besides, that's a requirement that'll be hard to meet. So my two-part
question is: Is this expected behavior? Is there a way around this?
