If you try to export this document:
#+BEGIN_SRC sql :exports both
select 1 limit 0;
#+END_SRC
It fails to export with an error in *Messages*:
user-error: Empty table - created default table
It also stops processing the document at that point.
(That SQL code produces no output but is not a SQL error.)
I'd prefer if it would just leave that empty (missing) table out, and keep
going. Is there any way to do that?

Here's a simple patch to fix this, if people are interested.

Subject: [PATCH] Allow empty table creation on export, rather than giving
error.
This is useful with SQL which can produce no results sometimes.
