I've played with some self-join code but that's proving to be complicated.
The easiest approach is to maintain the window in your application code,
as you iterate over a simple SELECT statement.

Of course. You only ever call sqlite3_step step after prepare and before

I mean, you only ever call sqlite3_step *once* after prepare and before
to call sqlite3_step repeatedly, for as long as it
returns SQLITE_ROW. Every call fetches a new row. When sqlite3_step
returns SQLITE_DONE, there are no more rows.
