r each individual metric - what I need to figure out how to do is to be
able to build a SQLAlchemy ORM query by parsing the formula string, and
evaluating each operation in the context of the query. `func.sum` would
work for formula1, but I'd need to iteratively build the formula wit
Hello all,
I am in the process of trying to create a dynamic expression query engine
in an application I'm working on.
So there is a formula that gets defined like so:
formula = '"metric:123" + "metric:456" + "metric:789"'
Each metric maps to a column in the database tables - long story
:facepalm: i should have seen that much sooner. Thank you so much for your
help. No longer need to do any of that crazy stuff I attempted!

I am relatively new to using SQLAlchemy for more complex use cases. I am in
the process of creating a time series query, but I am unable to reference a
column by its alias at the top level of the query.
This is the query that I am trying to address that SQLAlchemy is currently
