Hi, I'm using SQLAlchemy 0.7.5 in a web application accessing several tables containing between 2.5 and 3.5 millions records; these tables are indexed correctly. Database is Oracle 10g (release 10.2.0.4).
My problem is quite simple : when querying the database through SQLAlchemy (via "session.query(MyClass).filter(...)"), the execution plan (when using indexed criterias) doesn't use table indexes but does a full scan which takes between 10 and 15 seconds; when querying the database through a simple SQL query (in Tora for example), indexes are normaly used and the result is immediate. I tried to play in SQLAlchemy with optimizer modes and hints, but it doesn't change anything. Any idea ?
