unable to insert into mysql table using python

Question

I'm trying to insert rows in my sql table using a csv file in python.

There are five columns (id(autoincrement, primary, int),Event(int), Edition(int), Subscription(varchar), Daystogo(varchar)

My csv has 4 columns (Event, Edition, Subscription, Daystogo). I want to insert these into the table and let id be assigned in autoincremental way.

mydb = mysql.connector.connect(
        user='user', password='password',
                              host='host',
                              database='opm')
mycursor = mydb.cursor()


csv_data=csv.reader("mycsvfile.csv")
for row in csv_data:
    print(row)
    mycursor.execute("INSERT INTO opm (Event, Edition, Subscription, Daystogo) VALUES (%s,%s,%s,%s)", (int,int,str, str))

This is the error that i have been receiving

csv_data=csv.reader("mycsvfile.csv")
for row in csv_data:
    print(row)
    mycursor.execute("INSERT INTO opm (Event, Edition, Subscription, Daystogo) VALUES (%s,%s,%s,%s)", (int,int,str, str))


['m']
Traceback (most recent call last):

    "Failed processing format-parameters; %s" % err)

ProgrammingError: Failed processing format-parameters; Python 'type' cannot be converted to a MySQL type

for code

mycursor.execute("INSERT INTO opm (Event, Edition, Subscription, Daystogo) VALUES (%s,%s,%s,%s)")

the error is

ProgrammingError: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s,%s,%s,%s)' at line 1

Please help me out how can I insert the rows in mysql table

Answer 1

Assuming your CSV has four columns,

mycursor.execute("INSERT INTO opm (Event, Edition, Subscription, Daystogo) VALUES (%s,%s,%s,%s)", row)

should work (the second parameter needs to be a list or a tuple with elements to be bound to the placeholders; since you have four placeholders, you need a four-element list or tuple of data (not data types !).
