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.
