Unable to import CSV file data to mysql table

Question

I am using the code below-

import mysql.connector
import csv

mydb = mysql.connector.connect(host='xxxxx', user='xxxx', passwd='xxxxxx')

cursor = mydb.cursor()
cursor.execute("SHOW DATABASES")
l = cursor.fetchall()

cursor.execute("USE DB ")

with open('details.csv','rt')as f:
    csv_data = csv.reader(f)

   for row in csv_data:
       cursor.execute ('INSERT INTO student (id,name,age,course) VALUES (%s,%s,%s,%s)',row)
cursor.close()
mydb.commit()
mydb.close()

I am getting the following error- "ProgrammingError: Not all parameters were used in the SQL statement" python 3.x,windows7,Mysql 2012 version.

Answer 1

In this case, the main problem is the string format. I did't know what object is row , in your error it is a list, so using each element will solve the issue.

for row in csv_data:
       cursor.execute ('INSERT INTO student (id,name,age,course) VALUES (%s,%s,%s,%s)',
row[0], row[1], row[2], row[3])

Answer 2

for row in csv_data:
    listval = []
    for col in row:
        listval.append(col)

    cursor.execute ('INSERT INTO student (id,name,age,course) VALUES (%s,%s,%s,%s) ', listval)

This will work :))
