that's the only way we can tell if a table exists. We catch the exception for DESCRIBE, determine that its the exception we expect, and return True or False. There have already been issues in the gaerdbms dialect regarding Google's exception formatting here being inconsistent. you should emulate the approach here: http://hg.sqlalchemy.org/sqlalchemy/file/21043b66fe2e/lib/sqlalchemy/dialects/mysql/gaerdbms.py#l67
