Hello,
I'm having a problem trying to cleanup sqlalchemy objects. My application
has a thread which handles DB connections. In some cases the thread dies
and I want to do a cleanup so, next time the thread is started it would be
able to reconnect again.
The steps I tried are:
Thank you!

Is there a way to do a batch insert and recover every rowid?
Thank you!!

Hello,
Using ORM, i'm inserting like that:
session.add(table_mapper(**datum))
And updating:
session.query(dest_table).filter_by(**filters).filter(filter_column >
from_date).update(datum, synchronize_session=False)
Is there a way to get returning rowid of the rows affected.

Hello!
Is there a way to redefine a table in metadata?
I'm trying to define a table without pk to create this way in the database,
and then trying to add the pk to the definition to use it.
But I'm always getting this error
sqlalchemy.exc.ArgumentError: Column object 'column' already assigned to
11 matches
