That's not the problem. The problem is that MySQLdb IS indeed using Python 
format substitution to do its argument substitution. Python expects the 
value for "%d" to be an integer. But MySQLdb has already converted all the 
argument values to strings. Hence the error.

If MySQLdb were doing its own parsing of the format string, it could produce 
a more meaningful error message when it sees "%d" (e.g. "only %s 
substitutions allowed").
