Writing to MySQL database with pandas using SQLAlchemy, to_sql

Alternatively, use pymysql package...

import pymysql
from sqlalchemy import create_engine
cnx = create_engine('mysql+pymysql://[user]:[pass]@[host]:[port]/[schema]', echo=False)

data = pd.read_sql('SELECT * FROM sample_table', cnx)
data.to_sql(name='sample_table2', con=cnx, if_exists = 'append', index=False)

Using the engine in place of the raw_connection() worked:

import pandas as pd
import mysql.connector
from sqlalchemy import create_engine

engine = create_engine('mysql+mysqlconnector://[user]:[pass]@[host]:[port]/[schema]', echo=False)
data.to_sql(name='sample_table2', con=engine, if_exists = 'append', index=False)

Not clear on why when I tried this yesterday it gave me the earlier error.

Using pymysql and sqlalchemy, this works for Pandas v0.22:

import pandas as pd
import pymysql
from sqlalchemy import create_engine

user = 'yourUserName'
passw = 'password'
host =  'hostName'  # either localhost or ip e.g. '172.17.0.2' or hostname address 
port = 3306 
database = 'dataBaseName'

mydb = create_engine('mysql+pymysql://' + user + ':' + passw + '@' + host + ':' + str(port) + '/' + database , echo=False)

directory = r'directoryLocation'  # path of csv file
csvFileName = 'something.csv'

df = pd.read_csv(os.path.join(directory, csvFileName ))

df.to_sql(name=csvFileName[:-4], con=mydb, if_exists = 'replace', index=False)

"""
if_exists: {'fail', 'replace', 'append'}, default 'fail'
     fail: If table exists, do nothing.
     replace: If table exists, drop it, recreate it, and insert data.
     append: If table exists, insert data. Create if does not exist.
