subquery relationships?

[Dan Stromberg]

Hi folks.

I have a subquery that is selected from a table with 5 foreign keys,
and joined with another table with 3 foreign keys.

And then that subquery is used in a join with the table having the 3
foreign keys again.

I don't know how to tell what column(s) that join is happening on.

What goes into SQLAlchemy's "thought process" when it joins a table
with a subquery?

Thanks!

docs for this are at:

https://docs.sqlalchemy.org/en/20/orm/join_conditions.html

there are several approaches to relationships with subqueries, the most open ended is the one described at https://docs.sqlalchemy.org/en/20/orm/join_conditions.html#relationship-to-aliased-class
