Hi everybody, is it possible in DAL/GAE to aggregate values by several criteri? E.g. SELECT SUM(x) where z <= 100 and z > 0 and y <= 1000 and y >= 200;
I have done a simple OLAP engine using 'multidimensional hierarchical clustering' approach, it does not need joins and works pretty fast in MySQL. I wonder if it's possible to port it to GAE, this may be a hit for reports generation and data storage in web2py. But I guess I heard about GAE limitation for only one possible comparison term per query. Sergey -- To unsubscribe, reply using "remove me" as the subject.
