Hi, I'm looking for a way to check for a table's existance. I know I can do it in 2 queries, once for checking the table and one for running the query, but I'd prefer to do it in one query with a try-except block.
What is the best way to do this? I'm using psycopg2 and I see that the raised error is "psycopg2.errors.UndefinedTable". However I cannot catch for this error, I can only catch for "sqlalchemy.exc.ProgrammingError". How can I catch specifically for psycopg2.errors.UndefinedTable inside sqlalchemy.exc.ProgrammingError? Or is there a better way to check for a table's existance? Since it'll be in an API I'd prefer to keep the query count low. -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
