Hi, Luis:

Yes, the CLI is where we're working with this one. The issue here is that
the CLI doesn't support WITH. Or am I missing some underlying thing in your
post?

Besides Rob's excellent suggestion, I seem to remember that SEQUEL had
a CLI
interface. Have you checked that?

Create a view with that statement. Access the view with SEQUEL?

I didn't, but that's a very good idea.

However, it's not a complete solution since some uses of this,
against
my
fervent complaints, will be implemented using the SEQUEL product,
which
has
no support for the WITH statement (among many other things).
Don't

me
started.

Any response to the "is it expected behavior" part?

did you try to use an CTE?

With x as (Select TRNADAT, Amount
From MyTable
Where ...
Order By TRNDAT)
Select x.* MTD(Amount)
From x
;

Betreff: SQL row processing order for UDF

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?
