There is actually nothing wrong with this particular example.  I realize
you are pointing out an issue that can happen, so this is a just "for the
record" post.  In this case the concatenation is done at compile time.
See:

http://www.java-performance-portal.org/article6.html

Further the usage of string concatenation is easier to read/write so you
need to actually consider wether the code in question is actually a
hotspot and worth StringBuffer(ifying).  Again your example is pointing to
a database query in which case so many other things are going on it's
unlikely to make any performance difference.
