redirecting stdout to mysql table

P: n/a

i would like to redirect stdout/err to a mysql table and would like a)
some peer review and b) suggestions for hardening the approach for a
general purpose class. thank you very much.
import sys
import MySQLdb

class DBLogger(object):
def __init__(self):
self.db_name = 'odb'
self.db_host = ''
self.db_table = 'sftp_manager_log'
self.db_uname = 'roo'
self.db_passwd = ''
self.db_port = 3306
self.db = None
self.cur = None
self.sql = 'INSERT INTO %s' %self.db_table + ' VALUES(null, NOW
(), %s)'
def openDb(self):
self.db = MySQLdb.connect(host = self.db_host,
user = self.db_uname,
passwd = self.db_passwd,
db = self.db_name,

self.cur = self.db.cursor()
return self.db, self.cur
except Exception, e:
sys.stdout = sys.__stdout__
sys.stderr = sys.__stderr__
print e[0], e[1]

def closeDb(self):

def write(self, string):
s = string.strip('\n')
if not s=='':
self.cur.execute(self.sql, (s))
dbl = DBLogger()
sys.stdout = dbl
sys.stderr = dbl

print 'a b c '
sys.stdout = sys.__stdout__
sys.stderr = sys.__stderr__
thanks again for taking the time.

n00b def openDb(self):
n00b try:
n00b self.db = MySQLdb.connect(host = self.db_host,
n00b user = self.db_uname,
n00b passwd = self.db_passwd,
n00b db = self.db_name,
n00b )
n00b self.cur = self.db.cursor()
n00b return self.db, self.cur
n00b except Exception, e:
n00b sys.stdout = sys.__stdout__
n00b sys.stderr = sys.__stderr__
n00b print e[0], e[1]
n00b sys.exit(1)
n00b def write(self, string):
n00b s = string.strip('\n')
n00b if not s=='':
n00b self.openDb()
n00b self.cur.execute(self.sql, (s))
n00b self.db.commit()
n00b self.closeDb()

You don't really want to open a new database connection for every write call
do you?
