You could log begin/end transaction (along with any other statements) by installing sqlite3_trace hook. Another approach would be to use sqlite3_commit_hook, sqlite3_rollback_hook, sqlite3_get_autocommit. Call sqlite3_get_autocommit from inside your custom function to see whether the statement is part of an explicit transaction. sqlite3_commit_hook and sqlite3_rollback_hook tell you when a transaction ends. The first query that's part of an explicit transaction after a previous transaction (if any) has ended, starts a new one. By the way, see sqlite3_update_hook. Perhaps you could use that in lieu of your triggers. Igor Tandetnik
