It seems like you can define "procedures" in org-mode and call them from
elsewhere, with args.
But I'm not sure how well-defined that process is; the documentation is not
completely perfect yet I think. Here's one thing I'm trying that seems not
to work.
I define a "procedure" as a named ref called recorddate with two args, ver
and order. The idea is I could later call that with different values of
those args.
#+NAME: recorddate(order="desc")
#+BEGIN_SRC sql :exports none :colnames no :results scalar
select Event.CreatedAt from Event join MachineInfo as MI on
Event.MachineInfoId=MI.Id
where Event.CreatedAt is not NULL order by CreatedAt $order limit 1;
#+END_SRC sql
(BTW, I really like how $ vars are substituted into SQL. Nice.) But when
I try to call it like this:
* earliest record is call_recorddate(ver="'.'", order="asc")
or like this:
#+CALL: recorddate(ver="'.'", order="asc")
and I try to export as LaTeX (or anything), I get
org-babel-ref-resolve: Reference 'recorddate' not found in this buffer
Is this supposed to work?
