Hello,
When returning results from a postgresql database, if the first value is
NULL then no results are returned.
Versions: orgmode git commit c01c2ad Fri Mar 18, postgresql 9.0.3.
This works as expected:
#+begin_src sql :engine postgresql :cmdline -d postgres
SELECT 1 as A, NULL as B;
#+end_src
#+results:
| a | b |
| 1 | |
#+begin_src sql :engine postgresql :cmdline -d postgres
SELECT 1 as A, 1 as B;
#+end_src
#+results:
| a | b |
| 1 | 1 |
When the first value is NULL then only the column names are returned:
#+begin_src sql :engine postgresql :cmdline -d postgres
SELECT NULL as A,1 as B;
#+end_src
#+results:
| a | b |
|---+---|
whereas I would have expected this:
#+begin_example
| a | b |
| | 1 |
#+end_example
A slightly unsatisfactory workaround using coalesce, is:
#+begin_src sql :engine postgresql :cmdline -d postgres
SELECT coalesce(NULL,'NULL') as A,1 as B;
#+end_src
#+results:
| a | b |
| NULL | 1 |
Also, this may be unrelated, when trying to return tuples only, using
"-t", this happens:
#+begin_src sql :engine postgresql :cmdline -d postgres -t
SELECT NULL as A,1 as B;
#+end_src
#+results:
| | | | | |
|---+---+---+---+---|
| | | | | |
Thanks,
Myles
