Detecting a schema change requires starting a read transaction. The sqlite3_step() interface (usually) starts a read transaction, and so it will detect the schema change, and will cause the statement to automatically adjust to the new schema. But sqlite3_column_count() does *not* start a new transaction. The sqlite3_column_count() bases its answer on whatever schema was current during last transaction for that connection. -- D.
