Fine tuning Java Code

Question

If create a query in Java....something like
StringBuffer Test= new StringBuffer("SELECT order, status_date, sales_order_number,")
               .append(" site_no, project_no, customer_number")                    .append(" price_list, voc_date, bill_required, ship_to, bill_to")
                    .append(" FROM order_head")
                    .append(" WHERE order_no = ?");
String query = Test.toString();
If I use string concatenation here......<string>.concat() instead of StringBuffer......will it enhance the code performance ?

"We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil."
-- Donald Knuth
String test = "SELECT order, status_date, sales_order_number," +
        " site_no, project_no, customer_number" +
        " price_list, voc_date, bill_required, ship_to, bill_to" +
        " FROM order_head" +
        " WHERE order_no = ?";
