  In a sense, as long as the syntax is considererd, albeit with

  a general-purpose programming language:

  It is known that Lisp is a general purpose and Turing complete
  language, using only expression of the atom form or list form:

( f x y ... z )

  where each letter might be an atom or a list itself, such as in

( f ( g x ) y )

  Now, my idea was to write this (abusing SQL) as:

SELECT * FROM F
WHERE ARG =( SELECT * FROM G WHERE ARG = X )
AND ARG1 = Y;

  This would even be able to handle nicely the multiple return
  values, which are possible in Lisp. Some other features of the
  SQL syntax are useful as well.

  So one could implement a programming language based on SQL
  syntax.
           


  Remarkable idea!

  The SQL-syntax based notation could look like:

SELECT * FROM( SELECT NEW FROM GRID_BAG_CONSTRAINTS )
WHERE GRIDX = 0
AND GRIDY = 0
AND GRIDWIDTH = 2
AND GRIDHEIGHT = 1
AND ... ;
