Pandas writing dataframe to other postgresql schema

Question

I am trying to write a pandas DataFrame to a PostgreSQL database, using a schema-qualified table.

I use the following code:

import pandas.io.sql as p         


        

Answer 1

Solved, thanks to joris answer. Code was also improved thanks to joris comment, by passing around sqlalchemy engine instead of connection objects.

import pandas as pd
from sqlalchemy import create_engine, MetaData

engine = create_engine(r'postgresql://some:user@host/db')
meta = sqlalchemy.MetaData(engine, schema='a_schema')
meta.reflect(engine, schema='a_schema')
pdsql = pd.io.sql.PandasSQLAlchemy(engine, meta=meta)

df = pd.read_sql("SELECT * FROM xxx", con=engine)    
pdsql.to_sql(df, 'test')
