Hi,
When I set engine as below,
engine =
sa.create_engine('redshift+psycopg2://usern...@xxx-edm-oregon-prod02.cgdmyxu24bfx.us-west-2.redshift.amazonaws.com:5439/bdpdw?tcpKeepAlive=true&ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory')
it's no error. But when I try to
print(engine.table_names())
it gave me this error
ProgrammingError: (psycopg2.ProgrammingError) invalid dsn: invalid connection
option "tcpKeepAlive"
(Background on this error at: http://sqlalche.me/e/f405)
and then I try this way
engine =
sa.create_engine('redshift+psycopg2://usern...@xxx-edm-oregon-prod02.cgdmyxu24bfx.us-west-2.redshift.amazonaws.com:5439/bdpdw')
then print(engine.table_names())
it gave me this error message
OperationalError: (psycopg2.OperationalError) fe_sendauth: no password supplied
(Background on this error at: http://sqlalche.me/e/e3q8)
Not sure, how should i do?
