Connect to AWS RDS Postgres database with python
Thank's John Rotenstein for your comment.
As he pointed out, my-rds-table-name is the database instance name, not the database name, the default database name is postgres.
import psycopg2engine = psycopg2.connect( database="postgres", user="my_user_name", password="abc123def345", host="my-rds-table-name.123456.us-east-1.rds.amazonaws.com", port='5432')
Using sqlalchemy you can do the following:
engine = create_engine('postgresql://postgres:postgres@<AWS_RDS_end-point>:5432/postgres')Then you can update your database.For example:
df = pd.DataFrame({'A': [1,2], 'B':[3,4]})df.to_sql('tablename', engine, schema='public', if_exists='append', index=False)
