from twisted.enterprise import adbapi
from twisted.internet import reactor
from twisted.spread import pb

DB_HOST = "localhost"
DB_USER = "root"
DB_PASSWD = "xxx"
DB_NAME = "account"

class DBException(pb.Error): pass

dbpool = adbapi.ConnectionPool("MySQLdb", host=DB_HOST, user=DB_USER, 
passwd=DB_PASSWD, db=DB_NAME)

# Database checking
def getClientsDBParams(username):
     _sql = """
     SELECT username, password, ip, netmask, mac FROM bunkernet_clients
         WHERE username='%s'
     """ % username
     return dbpool.runQuery(_sql)

def dbClientSucceeded(self, l):
     if l:
         print l
         print "no records"
         raise DBException("No records")

def dbClientFailed():
     print "Failed!"


The problem here is that when dbClientSucceeded is executed and i get 
"no records" - i don't get exception. Only when i press Ctrl + C on 
server i get those DBException. This code will be executed when remote 
client connects to server and i want those DBException be passed to 
remote client but i can't get it, can get it only with Ctrl + C

Your help is very appreciated.
Thanks in advance.

Best regards,
