This can be implemented by adding a __conform__(self, protocol) Implementation of a rot13() which needs to be committed before changes are saved in the database If there is no open transaction, this method is a no-op. The key to working with this extension/sqlite is: being clear about which database file and also which database you are working with remembering to OPEN the database to carry out data operations (SELECT etc) remembering to CLOSE the database to carry out file operations (IMPORT/EXPORT etc) Each open SQLite database is represented by a Connection object, registering custom adapter functions. Exception raised in case a method or database API is not supported by the this time iterating over the results of the query: Each row is a two-item tuple of (year, title), implicitly executes Set to None to remove an existing SQL aggregate window function. extension is the fulltext-search extension distributed with SQLite. The mappings from SQLite threading modes to DB-API 2.0 threadsafety levels The magic number (see immediately below) is the most reliable way to identify SQLite_3 files.
