No, but its not all that expensive and relatively easy to find at bookstores.  It's also been around a while, so there's a chance that you may be able to borrowa copy from a library, friend, coworker, etc.

Of course the publisher will not give away their contents for free. But they do supply program code. Download http://examples.oreilly.com/lex/progs.zip and study sql1.y, sql2.y and sqltext.c

There is also a Perl based SQL parser at http://www.cpan.org/modules/by-module/SQL/SQL-Statement-1.003.tar.gz
