SQL support in Babel

SQL support in Babel

[Seb]

Hi,

The last code block in ob-doc-sql¹ suggests I should be able to place a
number of #+HEADER lines above my SQL source code to specify the
connection string.  I am trying to connect to a remote PostgreSQL
server, and after lots of experimentation, the only way this works for
me is to have a single #+HEADER line with a :cmdline with the entire
connection string.  All the other header arguments (:database, :dbuser,
etc.), whether in separate lines or in a single one, seem to be
completely ignored.  Using Org 8.2.10 and Emacs 24.4.1 from Debian Sid
packages.  Is this a problem with this version combination, or does the
functionality of the header arguments depend on the engine being used?
Thanks.

FWIW, the following worked fine for me:

#+name: my-query
#+header: :engine postgresql
#+header: :dbhost <host>
#+header: :dbuser <user>
#+header: :dbpassword <password>
#+header: :database sheetmusic
#+begin_src sql
  SELECT id, creator, title, category, boxnumber FROM music
  WHERE id > 300;
#+end_src

#+RESULTS: my-query

|                      id | creator | title                                                             | category  | boxnumber |
