No. It uses the preprocessor to generate something like
metaparse::string<'s','e','l','e','c','t',' ','n',',...>
The downside is, that metaparse has a configurable maximum string length
and
increasing it also increases compile times. I am not sure, weather it
would be
possible to have reasonable compile times with SQL strings as they exist
in
real world applications.
doesn't it still makes impossible to have variables in the request?
Yes and no. That could be solved with positional parameters like 
boost::format:

db.run(QUERY("select name,salary from persons where id=%1" % 17));
