Trapping MySQLdb warnings

[Tim Johnson]

Using Python 2.6.5 on linux.

When using MySQLdb I am getting warnings printed to stdout, but I would
like to trap, display and log those warnings.

In the past I have used _mysql_exceptions.Warning, but that approach
is not working in this case.

My cursor is created with the relevant following code:

## connection object
self.__conn = MySQLdb.connect(db = self.__db,
host = self.__host, user = self.__user,
passwd = self.__passwd)

## cursor object
self.__rdb = self.__conn.cursor()
## And implemented as :
try :
self.__rdb.execute(S)
except _mysql_exceptions.Warning,e:
raise e ## replace with log(e)

What else needs to be done?
TIA
