I'm looking for a way to create a postgres table from a pandas dataframe, and then read the postgre table directly in pgAdmin.
I've found a way to do that thanks to this link : How to write DataFrame to postgres table? .
The command is :
from sqlalchemy import create_engine
engine = create_engine('postgresql://username:password@host:port/database')
df.to_sql('table_name', engine)
However, I don't know what is 'table_name'. Do I have to create a table in my Data Base?
Thanks for your help!

Ok, the thing is that I have an error :NameError: name 'bat_prediction_rf' is not defined. The last lign of my code isbaonotnull_test.to_sql(bat_prediction_rf, engine). Maybe it's because of the schema. I explain ; I would like to create a table names 'bat_prediction_rf' in the schema p_baobat itself in the database db. I don't understand why I have this error...

@Pollux should that bebaonotnull_test.to_sql('bat_prediction_rf', engine)(note here'bat_prediction_rf'is a string) or isbat_prediction_rfa variable defined somewhere else in your code?

@Pollux should that be
baonotnull_test.to_sql('bat_prediction_rf', engine) (note here 'bat_prediction_rf' is a string) or is bat_prediction_rf a variable defined somewhere else in your code?– Rob Bricheno
