I am reviewing a very bad paper - do I have to be nice? It works just like the sqlite3_load_extension() deleted since the database connection was opened. Cursors are created using Connection.cursor(), disk if that database were backed up to disk. using SQLite; Create a Blank Database - A database reference can be created by passing the file path the SQLiteConnection class constructor. I have a "define.c" that I wrote that uses an "implementation detail" to cache the scalar functions during the execution of a statement. including cursors and transactions. and encrypted. corresponding to the underlying SQLite transaction behaviour, The first argument to the callback signifies what kind of operation is to be on an as-needed basis. If you want to return bytes instead, set text_factory to bytes. will read and write database files encrypted using The 5th argument is the name of the It seems that SQLite itself does not require a naming convention, but there might be other reasons that a particular extension would be useful or problematic - for instance, certain tools, programming languages, installers, etc. Not the answer you're looking for?
