>From a quick look at MySQLdb-1.2.2, it seems to be using the python std lib module warnings to report warnings. http://docs.python.org/library/warnings.html >From the warnings docs, it seems like warnings.simplefilter() is what you are looking for. Try this, perhaps in your wrapper module: import warnings import MySQLdb warnings.simplefilter("error", MySQLdb.Warning) I think that will tell the warnings module to treat MySQLdb.Warning as an error.
