Subject: [Babel] Lisp error: (wrong-type-argument listp hline)
Date: Mon, 23 Sep 2013 16:16:37 +0200	[thread overview]
Message-ID: <86zjr3bp2y.fsf@somewhere.org> (raw)

Hello Eric,

This ECM does generate an error, when run with ":hlines yes".

#+name: table
| Key | Value |
|-----+-------|
| ABJ |     1 |
| DEK |     2 |

As you can see, there is one header and one horizontal line in the input
table.

* Set :hlines to "no"

Adding `:hlines no' strips the horizontal line, but does keep the header.

  #+begin_src emacs-lisp :var data=table :results output :hlines no
  (mapc (lambda (item) (princ (format "UPDATE dim SET val=%s WHERE code='%s'\n"
                                      (nth 1 item) (nth 0 item))))
   data)
  #+end_src

  #+results:
  #+begin_example
  UPDATE dim SET val=Value WHERE code = 'Key'              <<< LINE NOT WANTED
  UPDATE dim SET val=1 WHERE code = 'ABJ'
  UPDATE dim SET val=2 WHERE code = 'DEK'
  #+end_example

* Set :hlines to "yes"

`:hlines yes' should leave the horizontal line, but generates an error.

  #+begin_src emacs-lisp :var data=table :results output :hlines yes
  (mapc (lambda (item) (princ (format "UPDATE dim SET val=%s WHERE code='%s'\n"
                                      (nth 1 item) (nth 0 item))))
   data)
  #+end_src

* Ignore the table header

Finally, how am I then supposed to *ignore the header line*?  By adding

  #+begin_src emacs-lisp
  (setq table (cdr table))
  #+end_src

?

Do I have to do that explicitly in my code block, or is there an option for
telling that to Babel?

Best regards,
  Seb
