TypeError when inserting a date
Posted by: Philippe Idlas

As far as I know I can insert a date into MySQL as long as the format corresponds to the date field attribute.
My date column in MySQL is declared as datetime.
So if I insert a date like '2013-04-21 11:29:00' into it it should work fine.
Indeed when I insert using phpmysql it works but when I insert from my python programm it fails with the following error message :

Traceback (most recent call last):
File "C:\Users\pidlas\Documents\", line 58, in <module>
File "C:\Users\pidlas\Documents\", line 46, in extract
cursor.execute(query, (serveur, etat, directive, regle, date,))
File "C:\Python27\lib\site-packages\MySQLdb\", line 183, in execute
query = query % db.literal(args)
TypeError: not all arguments converted during string formatting

I have tried different ways of formatting my python date variable but I could not until now found the right thing to do.

I would appreciate any ideas or thoughts.


My python code follows :

# -*- coding: utf-8 -*-
# modules nécessaires
from os import chdir
import MySQLdb as mdb
import sys
import datetime

# variables pour la BDD
serveur = ''
etat = ''
regle = ''
directive = ''

# répertoire où se trouve les logs

def extract(log):
for ligne in log:
debut_date = ligne.find('[')
fin_date = ligne.find(']')
date = ligne[debut_date+1:fin_date-5]
date = datetime.datetime.strptime(date, "%Y-%m-%d %H:%M:%S")
sep_N = ligne.find('N:')
serveur = ligne[ligne.find('[',sep_N)+1:ligne.find(']',sep_N)]
sep_S = ligne.find('S:')
etat = ligne[ligne.find('[',sep_S)+1:ligne.find(']',sep_S)]
sep_R = ligne.find('R:')
regle = ligne[ligne.find('[',sep_R)+1:ligne.find(']',sep_R)]
sep_D = ligne.find('D:')
directive = ligne[ligne.find('[',sep_D)+1:ligne.find(']',sep_D)]

db = mdb.connect('localhost', 'root', '', 'rudder');
cursor = db.cursor()
query = """INSERT IGNORE INTO serveur (nom_serveur) VALUES (%s)"""
cursor.execute(query, (serveur,))
query = """INSERT IGNORE INTO etat (nom_etat) VALUES (%s)"""
cursor.execute(query, (etat,))
query = """INSERT IGNORE INTO directive (nom_directive) VALUES (%s)"""
cursor.execute(query, (directive,))
query = """INSERT IGNORE INTO regle (nom_regle) VALUES (%s)"""
cursor.execute(query, (regle,))
query = """INSERT INTO serveur_etat_directive_regle (serveur, id_etat, id_directive, id_regle, date)
SELECT id_serveur, id_etat, id_directive, id_regle FROM serveur, etat, directive, regle
WHERE nom_serveur = %s AND nom_etat = %s AND nom_directive = %s AND nom_regle = %s"""
cursor.execute(query, (serveur, etat, directive, regle, date,))
except mdb.Error, e:
print "Error %d: %s" % (e.args[0],e.args[1])

return logfile
