Hi, I'm new to SQLAlchemy, and I was wondering if there's a way to test a condition while inserting. I'm trying to make my application use as few separate queries at the same time as possible. Here's a couple cases I have had issues with: Inserting something with a unique column if it doesn't exist. Right now, I am doing a select with a count() call. If I just insert it if it already exists I get an exception, but the exception doesn't propogate until the session is flushed. Also, I am having a tough time catching the SQLAlchemy exceptions. What's the best way to go about this? I have a join table where you have tags and things, and the join table tags the things. I want to test if it already exists and whatnot, and insert it in the same query if it doesn't.
Are there any good articles on optimizing your SQL queries and such?
