Error on insertion of data after successful opening of connection - database

Question

I'm inserting data from mysql table to postgres table and my code is:
from sqlalchemy import create_engine, MetaData, Table
from sqlalchemy.orm import mapper, sessionmaker
import psycopg2
class TestTable(object):
pass
class StoreTV(object):
pass
if __name__ == "__main__":
engine = create_engine('mysql://root#localhost:3306/irt', echo=False)
Session = sessionmaker(bind=engine)
session = Session()
metadata = MetaData(engine)
test_table = Table('test_1', metadata, autoload=True)
store_tv_table = Table('roku_store', metadata, autoload=True)
mapper(TestTable, test_table)
mapper(StoreTV, store_tv_table)
res = session.query(TestTable).all()
print res[1].test_1col
tv_list = session.query(StoreTV).all()
for tv in tv_list:
tv_data = dict()
tv_data = {
'title': tv.name,
'email': tv.business_email
}
print tv_data
conn = psycopg2.connect(database="db", user="user", password="pass", host="localhost", port="5432")
print "Opened database successfully"
cur = conn.cursor()
values = cur.execute("Select * FROM iris_store")
print values
cur.execute("INSERT INTO iris_store(title, business_email) VALUES ('title':tv_data[title], 'business_email':tv_data[business_email])")
print "Record created successfully"
conn.commit()
conn.close()
And I'm not able to get data from postgres data and insert into postgres table
while I'm successful to get data from Mysql table
ERROR is:
something
{'email': 'name#example.com', 'title': "Some Name"}
Opened database successfully
None
Traceback (most recent call last):

you have to check your data type for email to insert data.
because to insert data from mysql to postgres you have to both fields of same type.
click here and page no 28 will describe you aboout the data types of mysql and postgres

Answer 2

Your main problem is that you hava a sql syntax error in your insert query. It should look something like this:
cur.execute("INSERT INTO iris_store(title, business_email) VALUES (%(title)s, %(email)s)", tv_data)
For reference, see: Passing parameters to SQL queries
Also you probably don't want to create a new connection to your postgres db for each single value in tv_list, you should move the connect and close calls outside of the for loop, and printing the whole table each time also doesn't seem very useful
