Running a python with MySQL insert command getting an error on parameters

Question

I am trying to do an insert from Python to MySQL and I am getting

mysql.connector.errors.ProgrammingError: Not enough parameters for the SQL statement;

I have had a bit of a look online and I know its got something to do with tuble but I can't work out what to change, I have looked around and at my code, there are 10 items in the responce_data, 10 in the SQL and I have 10 %s so I don't know where I am going wrong

 import urllib.parse
import requests
import mysql.connector


mydb = mysql.connector.connect(
  host="localhost",
  user="root",
  passwd="**",
  database="flightdata"
)

mycursor = mydb.cursor()


main_api = 'https://www.sydneyairport.com.au/_a/flights/?query=&flightType=departure&terminalType=domestic&date=2019-11-10&sortColumn=scheduled_time&ascending=true&showAll=true'

address = 'lhr'
url = main_api + urllib.parse.urlencode({address: address})

response_data = requests.get(url).json()
for element in response_data['flightData']:
    flight_id = element['id']
    airline = element['airline']
    destination = element['destinations']
    flightNumbers = element['flightNumbers']
    scheduledTime = element['scheduledTime']
    estimatedTime = element['estimatedTime']
    scheduledDate = element['scheduledDate']
    latestTime = element['latestTime']
    status = element['status']
    statusColor = element['statusColor']

    sql = "INSERT INTO flightinfo (id, airline, destinations, flightNumbers, scheduledTime, estimatedTime, scheduledDate, latestTime, status, statusColor) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)"

    #sql = "INSERT INTO flightinfo (flight_id, airline, destination, flightNumbers, scheduledTime, estimatedTime, estimatedTime, scheduledDate, latestTime, status, statusColor ) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s ,%s))"
    val = [(flight_id, airline, " ".join(destination), ", ".join(flightNumbers), scheduledTime, estimatedTime,
            scheduledDate, latestTime, status, statusColor)]

mycursor.executemany(sql, val)

mydb.commit()

print(mycursor.rowcount, "was inserted.")


print(airline, destination, flightNumbers, scheduledTime, "Estimated Time:" + " " + estimatedTime, "Scheduled Date:" + " " + scheduledDate, "Latest Time:" + " " + latestTime, "Status:" + " " +status, "Status Color:" + " " + statusColor)

You sql is wrong it has 11 table columns instead of 10 because of duplicate entry of estimatedTime — dennohpeter

Remove the trailing , in val and change val to be

val = [(flight_id, airline, destination, flightNumbers, scheduledTime, estimatedTime, scheduledDate, latestTime, status, statusColor)]

And don't forget to fix your sql to

sql = "INSERT INTO flightinfo (flight_id, airline, destination, flightNumbers, scheduledTime, estimatedTime, scheduledDate, latestTime, status, statusColor) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)"

UPDATE: And to avoid getting

TypeError: Python 'list' cannot be converted to a MySQL type

You can convert the relevant fields to string for instance in your case you can do.

val = [(flight_id, airline, " ".join(destination), ", ".join(flightNumbers), scheduledTime, estimatedTime, scheduledDate, latestTime, status, statusColor)]
