An SQLITE_TRACE_CLOSE callback is invoked when a database connection closes. The P argument is a pointer to the database connection object and the X argument is unused.

An SQLITE_TRACE_PROFILE callback provides approximately the same information as is provided by the sqlite3_profile() callback. The P argument is a pointer to the prepared statement and the X argument points to a 64-bit integer which is approximately the number of nanoseconds that the prepared statement took to run. The SQLITE_TRACE_PROFILE callback is invoked when the statement finishes.

An SQLITE_TRACE_ROW callback is invoked whenever a prepared statement generates a single row of result. The P argument is a pointer to the prepared statement and the X argument is unused.

An SQLITE_TRACE_STMT callback is invoked when a prepared statement first begins running and possibly at other times during the execution of the prepared statement, such as at the start of each trigger subprogram
