I'm using Python with pywin32's adodbapi to write a script to create a SQL Server database and all its associated tables, views, and procedures. The problem is that Python's DBAPI requires that cursor.execute() be wrapped in a transaction that is only committed by cursor.commit(), and you can't execute a drop or create database statement in a user transaction. Any ideas on how to get around that?
EDIT:
There does not seem to be anything analogous to an autocommit parameter to either the connect() method of adodbapi or its cursor() method. I'd be happy to use pymssql instead of adodbapi, except that it truncates char and varchar datatypes at 255 characters.
I did try this before posting; here's the traceback.
