For completeness, it's worth mentioning in passing that % is only special when you're doing string formatting. It's not otherwise special in strings. > However, as Alan said, the method with the question mark to construct > the query is more safe than this. Way way way way way safer. In fact, forget that you can even use string formatting to put values into SQL queries. At all. Unless you know precisely what you're doing. And even then don't do it. Really. That way lies madness. And more, larger, and more disastrous SQL database problems than possibly any other error. If your library supports specifying a SQL query string using placeholders (and supplying those values in a tuple which the database module will paste in on its own), it will know to properly quote or escape special characters in those data values. Some modules use ? as the place holder, others use %s (even for numeric values, interestingly enough). Check with your documentation. --steve _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
