You will not see my regex fault with your examples. My regex will stumble with this sql.

I expected to see SQL parser solution in this thread, like this 

my $p = SQLParser->new(type=>'mysql', sql=>$sql)
  or die SQLParser->error();

$p->prettyprint(1);
$p->without_comment(1);
print $p->sql;

At first I looked SQL::Parser. It seems quite near for such tasks, but I couldn't find good solution to rip off comments. Do you know such module?
