RE: Can I do this?

Posted By: Kennedy, Randy
Date: Tuesday, 3 May 2011, at 4:57 p.m.

In Response To: Re: Can I do this? (Jonathan Leffler)

I apologize if my question isn't clear. I will try a different
explanation.

I have several functions that are select queries from tables/views with
additional logic paths in them, ultimately returning hundreds or
thousands of rows. All of these functions are date ranged so they take
2 dates as input parameters.
These 'detail' functions work great and I use them for many things,
mostly in automated monthly scripting.

I now need to create 'summary' functions for the rows that are returned
from the 'detail' functions. The easiest way to normally create a
summary query is to do aggregates within my select query on a table/view
and use group by. Unfortunately, these detail functions are more than
just a simple query, which is why they are functions. This would allow
me to know that the summary is always based on the exact same result as
the detail and if I need to change any logic, I only need to update the
detail function(s).

I found info on using the TABLE() function so I can do a select from
function just as I would from a table/view, so I thought I had an easy
solution as it worked fine when I tested using specific dates in the
function in the FROM.

However, when I wrap that aggregate query into a function so it can
accept the dates as input parameters (and be called from automated
scripting), it fails with the -217 errors.

I hope this makes sense, if not, please let me know and I will elaborate
anyway I can.

Thanks,
Randy

I looked briefly at the original question when you sent it, found it
hard to
make head or tail of, and filed it (leaving it for someone else to
answer -
clearly, someone else is on vacation at the moment, or otherwise
distracted).

I've looked marginally less briefly at this repeat of the question, and
I
still find it hard to understand what is being asked.

This syntax isn't valid SPL.

Did you mean:

CREATE FUNCTION FilingsSummary(p_StartDate DATE, p_EndDate DATE)

RETURNING DATE AS r_xyz, CHAR(20) AS r_pqr, ...

(And yes, that is extremely weird syntax.)

If the parameters are declared correctly but do not get passed to the
function correctly, then you may have a bug. You should be able to
demonstrate that with a relatively simple piece of SPL - two functions,
the
'inner' one generating data from (say) the orders table in the stores
database and the outer summarizing by customer, or something like that,
or
it could use your own simple schema. If the problem doesn't reproduce in

the small scale but does on the large scale, that may be a different
sort of
bug.

It is most certainly sensible to reuse functions rather than have two
lots
of 'the same' code to maintain.

AFAIK, it should work. If it does not work, we need to find out why not.
