Hi all,
I'm using sqlalchemy's reflection tools to get a Table object. I do this because these tables are dynamic and tables/columns can change. Here's the code I'm using:
def getTableByReflection(self, tableName, metadata, engine):
return Table(tableName, metadata, autoload = True, autoload_with = engine)
The problem is that when the above code is run twice it seems to return the same results regardless of whether or not the columns have changed. I have tried refreshing using the mysession.refresh(mytable) but that fails because the table is not attached to any metadata - which makes sense but then why am I seeing cached results?
Is there any way to tell the metadata/engine/session to forget about this table and let me load it cleanly?
