Detailed Description

RAII wrapper around QSqlDatabase::transaction()/commit()/rollback().

Begins a transaction on construction; rolls back in destructor unless commit() was called. Check ok() before issuing queries — begin can fail (e.g. driver doesn't support transactions, or one is already open).
