[sqlalchemy] Re: Data Inheritance
Thanks Michael. I might not explain it well, but I've traying to make some kind of data ( rows ) inheritance, this is copying a table value and all it's related childrens, and modify it as necesary with new values in an automated way. ( not inherit Table structures ) It's looks weird i think, I'll acomplish some similar stuff mannually beacause i dont think this already exists, if it does i could not fint anything like this.

[sqlalchemy] Data Inheritance
Hi, I'm planning to implement Data inheritance for an os project i'm working on [1]. I have a model with a few tables and relationships between them ( not a complicated stuff ) and i was wandering if there is a way to accomplish data inheritance in an automated way ( i can eventually make a script to accomplish this ) I mind, given a Parent id, I'd like to copy it and get all child copied and modified too. Does it possible ? if not, i will be manually doing it.. just making the whole model introspection by hand.. ( grr ) Any light on it would by great ! ( I'm having problems to explain on English what I'm trying to do. sorry about it) Thanks ! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups sqlalchemy group.

[sqlalchemy] Order_by
Hi guys, I'm new to this list but I I'm using SA from a while ago. I'm wondering how to sort a query based on a child table attribute. Table A- Many to One - Table B. I need to make a query in A, then order those records by a property of B. query = session.query(A).order_by( B.something ) B has an B.a relation attribute to A. Any pointers on how to achieve this ?

[sqlalchemy] Re: Order_by
I found the solution using Joins. Thanks anyways. This is it: query = session.query(A).select_from(join(A, B)).order_by(B.some_attr) cheers --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups sqlalchemy group.
