You don't really need to go the full ORM route to do this safely --
constructing SQL from user input is not only wrong from a security point of
view, but it's actually just harder to do it that way then use the
mechanisms provided in PEP-249 compliant DB-API modules. Life's easier if
you use parameterized queries, really :)
You're probably connecting to your database via a DB-API compatible library,
I assume? Most are. If so, it's simply a matter of:
cur = con.cursor()
cur.execute("SELECT name FROM blah WHERE id = ? AND zone = ?", (my_id,
my_zone))
All DB-API compliant modules support this, though some mark the parameters
differently. That's qmark, some alternates are numeric (:1, :2, etc), some
named (:id, :zone), some format (%s, %d, etc), some pyformat, (%(id)d,
%(zone)s).
The module should provide a 'paramstyle' stating what is supported.
