I try insert in database new entry in sale order :

    def test_mdel(self, cr, uid, id, vals, default=None, context=None):
    #val['name'] =self.pool.get('ir.sequence').get(cr, uid, 'sale.order') 
    #return super(sale_order, self).create(cr, uid, val, context=context)
    #self.write(cr, uid, ids, {'name': 'ffdfdd'})
    #val2 = vals.get('x_num_devis')


    cr.execute("SELECT nextval('sale_order_id_seq') FROM sale_order")
    next_id = cr.fetchone()[0]

    cr.execute("INSERT INTO sale_order (id,name,shop_id,date_order,partner_id,partner_invoice_id,partner_shipping_id,pricelist_id,currency_id,invoice_quantity) VALUES (%s,%s,%s,(now() at time zone 'UTC'),%s,%s,%s,%s,%s,%s)",(next_id,'test',1,6,6,6,1,'order'))
    msg = "Test " +str(next_id) 
    #new_id = self.pool.get('sale.order').create(cr, uid, {'name': 'New Name'})
    #cr.execute("Insert into sale_order (id) values (%s) where id=%d",(id))
    #INSERT INTO sale_order (write_date) VALUES ( (now() at time zone 'UTC'))
    _logger.error(msg)
    return True

But when i try this, i have a error :
