You seem to be forgetting one important detail… if a Rollback is called, the
underlying data and undo tables will be rolled back automatically. They are,
after all “real” tables in the database, and will be managed as such. Unless
you’re storing data outside the SQLite database, there is
When the command line and an application do different things, it is usually a
versioning issue. I’d verify what version of the SQLite library your Python
application is using. My guess is something older, possibly with a bug or
edge-case in the way it handles aliasing of views.

The WHERE clause takes only one parameter. WHERE expects an expression, which
evaluates down to one value. That expression does not need to be a comparison.
It commonly is, but it can be anything, such as a CASE expression, an EXISTS
subselect, or a function.

Chapter 10 of Using SQLite covers virtual tables. One of the examples given
shows how to wrap a PRAGMA statement, so it can be used as system catalog and
used in normal SELECT statements. It would be pretty easy to expand the given
