Question

I get this error when I run the script bellow, I am able to connect to Instagram API and to print nr of followers: mysql.connector.errors.InterfaceError: Failed executing the operation; Could not process parameters

followers = str(followers)
followersdata = [followers]



conn = mysql.connector.connect(user='root', password='XXX',
                              host='127.0.0.1',
                              database='InstagramStore')

cursor = conn.cursor()

q = """INSERT INTO InstagramFollowers (followers) VALUES (%s)"""

cursor.executemany(q, followersdata)
conn.commit() 

Answer 1

You can insert into multiple values in one execute with giving a list into execute command. The problem is in query.

First you should format your query via

query = """INSERT INTO InstagramFollowers {0} VALUES ({1})""".format(followers, values)

Then you should give your values in a list

cursor.execute(query, list)

Answer 2

You have your query incorrectly formatted. I didnt know what the second %s stood for in your query, so I just used the variable values to hold its place.

It should look more like:

Python <2.6

q = """INSERT INTO InstagramFollowers (%s) VALUES (%s)""" (followers, values)

Python >2.6

q = """INSERT INTO InstagramFollowers {0} VALUES {1}""".format(followers, values)

Python >3.6

q = f"""INSERT INTO InstagramFollowers {followers} VALUES {values}"""

Answer 3

You can use convert the list to json and write the json into the table.

INSERT INTO InstagramFollowers(followers) VALUES(json.dumps(followersdata))

This should work.
