hi everybody,

Sometimes I think it is useful to open a DB in readonly mode

eg. to avoid modifying by mistake

This is a patch to ob-sqlite.el to accomplish that

It adds support for opening a sqlite database in readonly only.

It does it by adding a babel parameter readonly. If present, the
database will be opened in readonly mode. Example:

#+begin_src sqlite :readonly :db /tmp/rip.db
insert into a values (1,2);
select * from a;
#+end_src

This will result in the following error:

Runtime error near line 2: attempt to write a readonly database (8)
[ Babel evaluation exited with code 1 ]
