The MySQLdb adapter converts all parameters to > properly delimited STRINGS (I don't know of any SQL system that passes > /binary/ numerics). But MySQLdb also uses Python % formatting to then I'd say the opposite: only poorly implemented systems convert numeric arguments to text. *Real* bound variables are passed as pointers. The SQL sentence can be prepared and re-used with different sets of values several times, without having to re-parse it again and again. If the MySQLdb adapter actually converts and inserts the arguments itself into the supplied SQL sentence, generating a new string for each call, this advantage -and many others- are cancelled, defeating the purpose of bound variables. -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
