Hmmm. Maybe the bug that was fixed by commit
0fd29a5ee7d14c3695b22998196373b9a3637413
about two weeks back? Make sure ob-R.el is up to date and compiled (or
that ob-R.elc is deleted).
Anyway, your code works as expected for me - first time.

FWIW, I prefer to use :var headers to import strings, but it takes some
setup:
--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC emacs-lisp
(defun grab-src (name)
(save-excursion
(org-babel-goto-named-src-block name)
(nth 1 (org-babel-get-src-block-info 'light))))
#+END_SRC
#+BEGIN_SRC R :var y=(grab-src "sqlsource") :results output :exports both
y
#+END_SRC
#+RESULTS:
: [1] "select \n * \nfrom \n t \nlimit \n 10"
--8<---------------cut here---------------end--------------->8---
HTH,
