mysqldb interfaceError (3 replies)

Hi all,

I have a very weird probleme with mysqldb (mysql module for python). I have a file with queries for inserting records in tables. If I call the functions from the file, it works just fine. But when I try to call one of the functions from another file it throws me a

_mysql_exception.InterfaceError: (0, '')

I really don't get what I'm doing wrong here..

I call the function from buildDB.py :

import create

create.newFormat("HD", 0,0,0)

The function newFormat(..) is in create.py (imported) :

from Database import Database

db = Database()

def newFormat(name, width=0, height=0, fps=0):
format_query = "INSERT INTO Format (form_name, form_width, form_height, form_fps) VALUES ('"+name+"',"+str(width)+","+str(height)+","+str(fps)+");"
db.execute(format_query)

And the class Databse is the following :

import MySQLdb from MySQLdb.constants import FIELD_TYPE

class Database():
def __init__(self):
server = "localhost"
login = "seq"
password = "seqmanager"
database = "Sequence"
my_conv = { FIELD_TYPE.LONG: int }

self.conn = MySQLdb.connection(host=server, user=login, passwd=password, db=database, conv=my_conv)
# self.cursor = self.conn.cursor()

def close(self):
self.conn.close()

def execute(self, query):
self.conn.query(query)

(I put only relevant code)

Traceback :

Z:\sequenceManager\mysql>python buildDB.py

The warning has never been a problem before so I don't think it's related.
