I can't do better than quote the sqlite documentation. I Hope this helps! http://docs.python.org/library/sqlite3.html """ Usually your SQL operations will need to use values from Python variables. You shouldn’t assemble your query using Python’s string operations because doing so is insecure; it makes your program vulnerable to an SQL injection attack. Instead, use the DB-API’s parameter substitution. Put ? as a placeholder wherever you want to use a value, and then provide a tuple of values as the second argument to the cursor’s execute() method. (Other database modules may use a different placeholder, such as %s or :1.) For example: # Never do this -- insecure! symbol = 'IBM' c.execute("... where symbol = '%s'" % symbol) # Do this instead t = (symbol,) c.execute('select * from stocks where symbol=?', t) # Larger example for t in [('2006-03-28', 'BUY', 'IBM', 1000, 45.00), ('2006-04-05', 'BUY', 'MSOFT', 1000, 72.00), ('2006-04-06', 'SELL', 'IBM', 500, 53.00), ]: c.execute('insert into stocks values (?,?,?,?,?)', t) """ -- Amaury Forgeot d'Arc _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
