Title: RE: [SQL] How does postgres handle non literal string values

I'm guessing it would have to be more like:
<%
                        String insertString =
                        "INSERT INTO  \"login\" (\'user\', \'password\')
VALUES ('"+username+"', '"+password+"')";
%>
to actually concatonate a string including the username & password variables, however I've not really used Java much so you might want to ask on the [EMAIL PROTECTED] list.
