As a general rule it is best to use placeholders in your SQL. It avoids all kind of nasty surprises, there is no need to quote the parameters yourself and although in this particular example I see no problem, why not always using a "Best Practice"? Also it makes for easier code IMHO.

Using join and map further avoids to have to check explicitly for the "end" condition. And personally I like map: it is so powerful and compact, yet still it conveys its meaning in a very clear way.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
