import sqlalchemy as sa

import datetime

import itertools

...

oracle_db = sa.create_engine('oracle://username:password@host:port/database')

connection= oracle_db.connect()

dat_ult_alt = datetime.datetime.now()

df_plano['DAT_ULT_ALT'] = pd.Series(list(itertools.repeat(dat_ult_alt, max)))

df_plano.to_sql('table_name', connection, if_exists='append', index=False)

I get DatabaseError: ORA-00904: "DAT_ULT_ALT": invalid identifier

How can I insert a datetime to a timestamp in oracle using to_sql from pandas with SQL Alchemy engine?
